SuSE: New Linux kernel packages fix remote denial of service

The openSUSE 11.2 kernel was updated to fix lots of security issues. In the rose networking stack it was possible for a remote host to provide more digipeaters than expected, resulting in heap corruption. Local attackers could send signals to their programs that looked like coming from the kernel, potentially gaining privileges in the context of setuid programs. The epoll subsystem did not prevent users from creating circular epoll file structures, potentially leading to a denial of service (kernel deadlock).

The code for evaluating OSF partitions contained a bug that leaks data from kernel heap memory to userspace for certain corrupted OSF partitions. The code for evaluating LDM partitions contained a bug that could crash the kernel for certain corrupted LDM partitions. The code for evaluating Mac partitions contained a bug that could crash the kernel for certain corrupted Mac partitions.

Specially crafted requests may be written to /dev/sequencer resulting in an underflow when calculating a size for a copy_from_user() operation in the driver for MIDI interfaces. Due to a failure to validate user-supplied indexes in the driver for Yamaha YM3812 and OPL-3 chips, a specially crafted ioctl request could have been sent to /dev/sequencer, resulting in reading and writing beyond the bounds of heap buffers, and potentially allowing privilege escalation. A page allocator issue in NFS v4 ACL handling that could lead to a denial of service (crash) was fixed.

net/ipv4/inet_diag.c did not properly audit INET_DIAG bytecode, which allowed local users to cause a denial of service (kernel infinite loop) via crafted INET_DIAG_REQ_BYTECODE instructions in a netlink message that contains multiple attribute elements, as demonstrated by INET_DIAG_BC_JMP instructions. The dvb_ca_ioctl function did not check the sign of a certain integer field, which allowed local users to cause a denial of service (memory corruption) or possibly have unspecified other impact via a negative value. The ax25_getname function did not initialize a certain structure, which allowed local users to obtain potentially sensitive information from kernel stack memory by reading a copy of this structure.

net/packet/af_packet.c did not properly initialize certain structure members, which allowed local users to obtain potentially sensitive information from kernel stack memory by leveraging the CAP_NET_RAW capability to read copies of the applicable structures. The get_name function did not initialize a certain structure, which allowed local users to obtain potentially sensitive information from kernel stack memory by reading a copy of this structure. The sctp_auth_asoc_get_hmac function did not properly validate the hmac_ids array of an SCTP peer, which allowed remote attackers to cause a denial of service (memory corruption and panic) via a crafted value in the last element of this array.

A stack memory information leak in the xfs FSGEOMETRY_V1 ioctl was fixed. Multiple buffer overflows in the caiaq Native Instruments USB audio functionality might have allowed attackers to cause a denial of service or possibly have unspecified other impact via a long USB device name. The sctp_process_unk_param function allowed remote attackers to cause a denial of service (system crash) via an SCTPChunkInit packet containing multiple invalid parameters that require a large amount of error data. The uart_get_count function did not properly initialize a certain structure member, which allowed local users to obtain potentially sensitive information from kernel stack memory via a TIOCGICOUNT ioctl call.

The rs_ioctl function did not properly initialize a certain structure member, which allowed local users to obtain potentially sensitive information from kernel stack memory via a TIOCGICOUNT ioctl call. The ntty_ioctl_tiocgicount function did not properly initialize a certain structure member, which allowed local users to obtain potentially sensitive information from kernel stack memory via a TIOCGICOUNT ioctl call. A race condition in the __exit_signal function allowed local users to cause a denial of service via vectors related to multi threaded exec, the use of a thread group leader, and the selection of a new thread group leader in the de_thread function.

fs/exec.c did not enable the OOM Killer to assess use of stack memory by arrays representing the arguments and environment, which allows local users to cause a denial of service via a crafted exec system call. Fixed cryptographic weakness potentially leaking information to remote users in the Orinoco wireless driver. The OSS sound subsystem incorrectly expected that a certain name field ends with a ‘\0’ character, which allowed local users to conduct buffer overflow attacks and gain privileges, or possibly obtain sensitive information from kernel memory. The blk_rq_map_user_iov function allowed local users to cause a denial of service (panic) via a zero-length I/O request in a device ioctl to a SCSI device. A kernel buffer overflow in the cuse server module was fixed, which might have allowed local privilege escalation.

An integer overflow in the ib_uverbs_poll_cq function allowed local users to cause a denial of service or possibly have unspecified other impact via a large value of a certain structure member. The install_special_mapping function did not make an expected security_file_mmap function call, which allowed local users to bypass intended mmap_min_addr restrictions and possibly conduct NULL pointer dereference attacks via a crafted assembly-language application. An integer underflow in the irda_getsockopt function allowed local users to obtain potentially sensitive information from kernel heap memory via an IRLMP_ENUMDEVICES getsockopt call.

The aun_incoming function allowed remote attackers to cause a denial of service by sending an Acorn Universal Networking (AUN) packet over UDP. The econet_sendmsg function allowed local users to cause a denial of service via a sendmsg call that specifies a NULL value for the remote address field. A stack-based buffer overflow in the econet_sendmsg function allowed local users to gain privileges by providing a large number of iovec structures. The ec_dev_ioctl function did not require the CAP_NET_ADMIN capability, which allowed local users to bypass intended access restrictions and configure econet addresses via an SIOCSIFADDR ioctl call.

The backend driver in Xen 3.x allows guest OS users to cause a denial of service via a kernel thread leak, which prevents the device and guest OS from being shut down or create a zombie domain, causes a hang in zenwatch, or prevents unspecified xm commands from working properly. The ipc subsystem did not initialize certain structures, which allowed local users to obtain potentially sensitive information from kernel stack memory via certain vectors. The copy_shmid_to_user function did not initialize a certain structure, which allowed local users to obtain potentially sensitive information from kernel stack memory via vectors related to the shmctl system call and the “old shm interface.”

The copy_semid_to_user function did not initialize a certain structure, which allowed local users to obtain potentially sensitive information from kernel stack memory. Updated packages are available from download.opensuse.org.

______________________________________________________________________________

1) Problem Description and Brief Discussion

  The openSUSE 11.2 kernel was updated to fix lots of security issues.

  This will probably be the last 11.2 kernel update released by the
  SUSE Security Team, as our suppport for 11.2 ends in 1 month.

  Following security issues were fixed:
  CVE-2011-1493: In the rose networking stack, when parsing the
  FAC_NATIONAL_DIGIS facilities field, it was possible for a remote
  host to provide more digipeaters than expected, resulting in heap
  corruption.  Check against ROSE_MAX_DIGIS to prevent overflows,
  and abort facilities parsing on failure.

  CVE-2011-1182: Local attackers could send signals to their programs
  that looked like coming from the kernel, potentially gaining privileges
  in the context of setuid programs.

  CVE-2011-1082: The epoll subsystem in Linux did not prevent users
  from creating circular epoll file structures, potentially leading to
  a denial of service (kernel deadlock).

  CVE-2011-1163: The code for evaluating OSF partitions (in
  fs/partitions/osf.c) contained a bug that leaks data from kernel heap
  memory to userspace for certain corrupted OSF partitions.

  CVE-2011-1012: The code for evaluating LDM partitions (in
  fs/partitions/ldm.c) contained a bug that could crash the kernel for
  certain corrupted LDM partitions.

  CVE-2011-1010: The code for evaluating Mac partitions (in
  fs/partitions/mac.c) contained a bug that could crash the kernel for
  certain corrupted Mac partitions.

  CVE-2011-1476: Specially crafted requests may be written to
  /dev/sequencer resulting in an underflow when calculating a size for a
  copy_from_user() operation in the driver for MIDI interfaces. On x86,
  this just returns an error, but it could have caused memory corruption
  on other architectures. Other malformed requests could have resulted
  in the use of uninitialized variables.

  CVE-2011-1477: Due to a failure to validate user-supplied indexes in
  the driver for Yamaha YM3812 and OPL-3 chips, a specially crafted
  ioctl request could have been sent to /dev/sequencer, resulting in
  reading and writing beyond the bounds of heap buffers, and potentially
  allowing privilege escalation.

  CVE-2011-1090: A page allocator issue in NFS v4 ACL handling that
  could lead to a denial of service (crash) was fixed.

  CVE-2010-3880: net/ipv4/inet_diag.c in the Linux kernel did not
  properly audit INET_DIAG bytecode, which allowed local users
  to cause a denial of service (kernel infinite loop) via crafted
  INET_DIAG_REQ_BYTECODE instructions in a netlink message that contains
  multiple attribute elements, as demonstrated by INET_DIAG_BC_JMP
  instructions.

  CVE-2011-0521: The dvb_ca_ioctl function in
  drivers/media/dvb/ttpci/av7110_ca.c in the Linux kernel did not check
  the sign of a certain integer field, which allowed local users to cause
  a denial of service (memory corruption) or possibly have unspecified
  other impact via a negative value.

  CVE-2010-3875: The ax25_getname function in net/ax25/af_ax25.c in the
  Linux kernel did not initialize a certain structure, which allowed
  local users to obtain potentially sensitive information from kernel
  stack memory by reading a copy of this structure.

  CVE-2010-3876: net/packet/af_packet.c in the Linux kernel did not
  properly initialize certain structure members, which allowed local
  users to obtain potentially sensitive information from kernel stack
  memory by leveraging the CAP_NET_RAW capability to read copies of
  the applicable structures.

  CVE-2010-3877: The get_name function in net/tipc/socket.c in the
  Linux kernel did not initialize a certain structure, which allowed
  local users to obtain potentially sensitive information from kernel
  stack memory by reading a copy of this structure.

  CVE-2010-3705: The sctp_auth_asoc_get_hmac function in net/sctp/auth.c
  in the Linux kernel did not properly validate the hmac_ids array of an
  SCTP peer, which allowed remote attackers to cause a denial of service
  (memory corruption and panic) via a crafted value in the last element
  of this array.

  CVE-2011-0711: A stack memory information leak in the xfs FSGEOMETRY_V1
  ioctl was fixed.

  CVE-2011-0712: Multiple buffer overflows in the caiaq Native
  Instruments USB audio functionality in the Linux kernel might have
  allowed attackers to cause a denial of service or possibly have
  unspecified other impact via a long USB device name, related to (1)
  the snd_usb_caiaq_audio_init function in sound/usb/caiaq/audio.c and
  (2) the snd_usb_caiaq_midi_init function in sound/usb/caiaq/midi.c.

  CVE-2010-1173: The sctp_process_unk_param function in
  net/sctp/sm_make_chunk.c in the Linux kernel, when SCTP is enabled,
  allowed remote attackers to cause a denial of service (system crash)
  via an SCTPChunkInit packet containing multiple invalid parameters
  that require a large amount of error data.

  CVE-2010-4075: The uart_get_count function in
  drivers/serial/serial_core.c in the Linux kernel did not properly
  initialize a certain structure member, which allowed local users to
  obtain potentially sensitive information from kernel stack memory
  via a TIOCGICOUNT ioctl call.

  CVE-2010-4076: The rs_ioctl function in drivers/char/amiserial.c in the
  Linux kernel did not properly initialize a certain structure member,
  which allowed local users to obtain potentially sensitive information
  from kernel stack memory via a TIOCGICOUNT ioctl call.

  CVE-2010-4077: The ntty_ioctl_tiocgicount function in
  drivers/char/nozomi.c in the Linux kernel did not properly initialize
  a certain structure member, which allowed local users to obtain
  potentially sensitive information from kernel stack memory via a
  TIOCGICOUNT ioctl call.

  CVE-2010-4248: Race condition in the __exit_signal function in
  kernel/exit.c in the Linux kernel allowed local users to cause a denial
  of service via vectors related to multi threaded exec, the use of a
  thread group leader in kernel/posix-cpu-timers.c, and the selection
  of a new thread group leader in the de_thread function in fs/exec.c.

  CVE-2010-4243: fs/exec.c in the Linux kernel did not enable the OOM
  Killer to assess use of stack memory by arrays representing the (1)
  arguments and (2) environment, which allows local users to cause a
  denial of service (memory consumption) via a crafted exec system call,
  aka an "OOM dodging issue," a related issue to CVE-2010-3858.

  CVE-2010-4648: Fixed cryptographic weakness potentially leaking
  information to remote (but physically nearby) users in the Orinoco
  wireless driver.

  CVE-2010-4527: The load_mixer_volumes function in sound/oss/soundcard.c
  in the OSS sound subsystem in the Linux kernel incorrectly expected
  that a certain name field ends with a '\0' character, which allowed
  local users to conduct buffer overflow attacks and gain privileges,
  or possibly obtain sensitive information from kernel memory, via a
  SOUND_MIXER_SETLEVELS ioctl call.

  CVE-2010-4668: The blk_rq_map_user_iov function in block/blk-map.c
  in the Linux kernel allowed local users to cause a denial of service
  (panic) via a zero-length I/O request in a device ioctl to a SCSI
  device, related to an unaligned map. NOTE: this vulnerability exists
  because of an incomplete fix for CVE-2010-4163.

  CVE-2010-4650: A kernel buffer overflow in the cuse server module
  was fixed, which might have allowed local privilege escalation.
  However only CUSE servers could exploit it and /dev/cuse is normally
  restricted to root.

  CVE-2010-4649: Integer overflow in the ib_uverbs_poll_cq function
  in drivers/infiniband/core/uverbs_cmd.c in the Linux kernel allowed
  local users to cause a denial of service (memory corruption) or
  possibly have unspecified other impact via a large value of a certain
  structure member.

  CVE-2010-4346: The install_special_mapping function in mm/mmap.c in
  the Linux kernel did not make an expected security_file_mmap function
  call, which allowed local users to bypass intended mmap_min_addr
  restrictions and possibly conduct NULL pointer dereference attacks
  via a crafted assembly-language application.

  CVE-2010-4529: Integer underflow in the irda_getsockopt function in
  net/irda/af_irda.c in the Linux kernel on platforms other than x86
  allowed local users to obtain potentially sensitive information from
  kernel heap memory via an IRLMP_ENUMDEVICES getsockopt call.

  CVE-2010-4342: The aun_incoming function in net/econet/af_econet.c in
  the Linux kernel, when Econet is enabled, allowed remote attackers
  to cause a denial of service (NULL pointer dereference and OOPS)
  by sending an Acorn Universal Networking (AUN) packet over UDP.

  CVE-2010-3849: The econet_sendmsg function in net/econet/af_econet.c
  in the Linux kernel, when an econet address is configured, allowed
  local users to cause a denial of service (NULL pointer dereference
  and OOPS) via a sendmsg call that specifies a NULL value for the
  remote address field.

  CVE-2010-3848: Stack-based buffer overflow in the econet_sendmsg
  function in net/econet/af_econet.c in the Linux kernel when an econet
  address is configured, allowed local users to gain privileges by
  providing a large number of iovec structures.

  CVE-2010-3850: The ec_dev_ioctl function in net/econet/af_econet.c
  in the Linux kernel did not require the CAP_NET_ADMIN capability,
  which allowed local users to bypass intended access restrictions and
  configure econet addresses via an SIOCSIFADDR ioctl call.

  CVE-2010-3699: The backend driver in Xen 3.x allows guest OS users to
  cause a denial of service via a kernel thread leak, which prevents the
  device and guest OS from being shut down or create a zombie domain,
  causes a hang in zenwatch, or prevents unspecified xm commands from
  working properly, related to (1) netback, (2) blkback, or (3) blktap.

  CVE-2010-4073: The ipc subsystem in the Linux kernel did not
  initialize certain structures, which allowed local users to obtain
  potentially sensitive information from kernel stack memory via
  vectors related to the (1) compat_sys_semctl, (2) compat_sys_msgctl,
  and (3) compat_sys_shmctl functions in ipc/compat.c; and the (4)
  compat_sys_mq_open and (5) compat_sys_mq_getsetattr functions in
  ipc/compat_mq.c.

  CVE-2010-4072: The copy_shmid_to_user function in ipc/shm.c in the
  Linux kernel did not initialize a certain structure, which allowed
  local users to obtain potentially sensitive information from kernel
  stack memory via vectors related to the shmctl system call and the
  "old shm interface."

  CVE-2010-4083: The copy_semid_to_user function in ipc/sem.c in the
  Linux kernel did not initialize a certain structure, which allowed
  local users to obtain potentially sensitive information from kernel
  stack memory via a (1) IPC_INFO, (2) SEM_INFO, (3) IPC_STAT, or (4)
  SEM_STAT command in a semctl system call.

2) Solution or Work-Around

  There is no known workaround, please install the update packages.

3) Special Instructions and Notes

  Please reboot the machine after installing the update.

4) Package Location and Checksums

  The preferred method for installing security updates is to use the YaST
  "Online Update" module or the "zypper" commandline tool. The package and
  patch management stack will detect which updates are required and
  automatically perform the necessary steps to verify and install them.

  Alternatively, download the update packages for your distribution manually
  and verify their integrity by the methods listed in Section 6 of this
  announcement. Then install the packages using the command

    rpm -Fhv <file.rpm>

  to apply the update, replacing <file.rpm> with the filename of the
  downloaded RPM package.

6) Authenticity Verification and Additional Information

 - Announcement authenticity verification:

   SUSE security announcements are published via mailing lists and on Web
   sites. The authenticity and integrity of a SUSE security announcement is
   guaranteed by a cryptographic signature in each announcement. All SUSE
   security announcements are published with a valid signature.

   To verify the signature of the announcement, save it as text into a file
   and run the command

     gpg --verify <file>

   replacing <file> with the name of the file where you saved the
   announcement. The output for a valid signature looks like:

     gpg: Signature made <DATE> using RSA key ID 3D25D3D9
     gpg: Good signature from "SuSE Security Team <security@suse.de>"

   where <DATE> is replaced by the date the document was signed.

   If the security team's key is not contained in your key ring, you can
   import it from the first installation CD. To import the key, use the
   command

     gpg --import gpg-pubkey-3d25d3d9-36e12d04.asc

 - Package authenticity verification:

   SUSE update packages are available on many mirror FTP servers all over the
   world. While this service is considered valuable and important to the free
   and open source software community, the authenticity and the integrity of
   a package needs to be verified to ensure that it has not been tampered
   with.

   The internal rpm package signatures provide an easy way to verify the
   authenticity of an RPM package. Use the command

    rpm -v --checksig <file.rpm>

   to verify the signature of the package, replacing <file.rpm> with the
   filename of the RPM package downloaded. The package is unmodified if it
   contains a valid signature from build@suse.de with the key ID 9C800ACA.

   This key is automatically imported into the RPM database (on
   RPMv4-based distributions) and the gpg key ring of 'root' during
   installation. You can also find it on the first installation CD and at
   the end of this announcement.

 - SUSE runs two security mailing lists to which any interested party may
   subscribe:

   opensuse-security@opensuse.org
       -   General Linux and SUSE security discussion.
           All SUSE security announcements are sent to this list.
           To subscribe, send an e-mail to
               <opensuse-security+subscribe@opensuse.org>.

   opensuse-security-announce@opensuse.org
       -   SUSE's announce-only mailing list.
           Only SUSE's security announcements are sent to this list.
           To subscribe, send an e-mail to
               <opensuse-security-announce+subscribe@opensuse.org>.
