SuSE: New IBM Java packages fix remote code execution

IBM Java 6 SR 5 was released fixing various bugs and critical security issues. Among many others, a vulnerability in the Java Runtime Environment (JRE) with initializing LDAP connections may be exploited by a remote client to cause a denial-of-service condition on the LDAP service. A vulnerability in Java Runtime Environment LDAP client implementation may allow malicious data from an LDAP server to cause malicious code to be unexpectedly loaded and executed on an LDAP client. Buffer overflow vulnerabilities in the Java Runtime Environment (JRE) with unpacking applets and Java Web Start applications using the unpack200 JAR unpacking utility may allow an untrusted applet or application to escalate privileges. A buffer overflow vulnerability in the Java Runtime Environment with processing PNG or GIF images as well as fonts may allow an untrusted Java Web Start application to escalate privileges. A vulnerability in the Java Runtime Environment (JRE) with storing temporary font files may allow an untrusted applet or application to consume a disproportionate amount of disk space resulting in a denial-of-service condition. A vulnerability in the Java Runtime Environment (JRE) HTTP server implementation may allow a remote client to create a denial-of-service condition on a JAX-WS service endpoint that runs on the JRE. Updated packages are available from download.opensuse.org.

______________________________________________________________________________

1) Problem Description and Brief Discussion

  IBM Java 6 SR 5 was released fixing various bugs and critical security
  issues:

  CVE-2009-1093: A vulnerability in the Java Runtime Environment (JRE)
  with initializing LDAP connections may be exploited by a remote client
  to cause a denial-of-service condition on the LDAP service.

  CVE-2009-1094: A vulnerability in Java Runtime Environment LDAP
  client implementation may allow malicious data from an LDAP server
  to cause malicious code to be unexpectedly loaded and executed on an
  LDAP client.

  CVE-2009-1095
  CVE-2009-1096: Buffer overflow vulnerabilities in the Java
  Runtime Environment (JRE) with unpacking applets and Java Web Start
  applications using the unpack200 JAR unpacking utility may allow an
  untrusted applet or application to escalate privileges. For example,
  an untrusted applet may grant itself permissions to read and write
  local files or execute local applications that are accessible to the
  user running the untrusted applet.

  CVE-2009-1097: A buffer overflow vulnerability in the Java Runtime
  Environment with processing PNG images may allow an untrusted Java Web
  Start application to escalate privileges. For example, an untrusted
  application may grant itself permissions to read and write local
  files or execute local applications that are accessible to the user
  running the untrusted application.

  CVE-2009-1097: A buffer overflow vulnerability in the Java Runtime
  Environment with processing GIF images may allow an untrusted Java Web
  Start application to escalate privileges. For example, an untrusted
  application may grant itself permissions to read and write local
  files or execute local applications that are accessible to the user
  running the untrusted application.

  CVE-2009-1098: A buffer overflow vulnerability in the Java Runtime
  Environment with processing GIF images may allow an untrusted applet
  or Java Web Start application to escalate privileges. For example,
  an untrusted applet may grant itself permissions to read and write
  local files or execute local applications that are accessible to the
  user running the untrusted applet.

  CVE-2009-1099: A buffer overflow vulnerability in the Java Runtime
  Environment with processing fonts may allow an untrusted applet
  or Java Web Start application to escalate privileges. For example,
  an untrusted applet may grant itself permissions to read and write
  local files or execute local applications that are accessible to the
  user running the untrusted applet.

  CVE-2009-1100: A vulnerability in the Java Runtime Environment (JRE)
  with storing temporary font files may allow an untrusted applet
  or application to consume a disproportionate amount of disk space
  resulting in a denial-of-service condition.

  CVE-2009-1100: A vulnerability in the Java Runtime Environment (JRE)
  with processing temporary font files may allow an untrusted applet or
  application to retain temporary files resulting in a denial-of-service
  condition.

  CVE-2009-1101: A vulnerability in the Java Runtime Environment (JRE)
  HTTP server implementation may allow a remote client to create a
  denial-of-service condition on a JAX-WS service endpoint that runs
  on the JRE.

  CVE-2009-1103: A vulnerability in the Java Plug-in with deserializing
  applets may allow an untrusted applet to escalate privileges. For
  example, an untrusted applet may grant itself permissions to read and
  write local files or execute local applications that are accessible
  to the user running the untrusted applet.

  CVE-2009-1104: The Java Plug-in allows Javascript code that is loaded
  from the localhost to connect to any port on the system. This may
  be leveraged together with XSS vulnerabilities in a blended attack
  to access other applications listening on ports other than the one
  where the Javascript code was served from.

  CVE-2009-1105: The Java Plug-in allows a trusted applet to be launched
  on an earlier version of the Java Runtime Environment (JRE) provided
  the user that downloaded the applet allows it to run on the requested
  release. A vulnerability allows Javascript code that is present in
  the same web page as the applet to exploit known vulnerabilities of
  the requested JRE.

  CVE-2009-1106: A vulnerability in the Java Runtime Environment with
  parsing crossdomain.xml files may allow an untrusted applet to connect
  to any site that provides a crossdomain.xml file instead of sites
  that allow the domain that the applet is running on.

  CVE-2009-1107: The Java Plugin displays a warning dialog for signed
  applets. A signed applet can obscure the contents of the dialog and
  trick a user into trusting the applet.

2) Solution or Work-Around

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

3) Special Instructions and Notes

  Please close and restart all running instances of IBM Java after the update.

4) Package Location and Checksums

  The preferred method for installing security updates is to use the YaST
  Online Update (YOU) tool. YOU detects which updates are required and
  automatically performs 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.

  Our maintenance customers are notified individually. The packages are
  offered for installation from the maintenance web:

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.
