SuSE: New IBM Java packages fix remote code execution

The IBM Java 1.4.2 JDK and JRE were brought to Service Release 13 and the IBM JDK and JRE 6 were brought to Service Release 4. Among other problems, a security vulnerability in the Java Runtime Environment (JRE) may allow an untrusted applet or application to list the contents of the home directory of the user running the applet or application. A security vulnerability in the Java Runtime Environment (JRE) with parsing zip files may allow an untrusted applet or application to read arbitrary memory locations in the process that the applet or application is running in. A vulnerability in Java Web Start and Java Plug-in may allow hidden code on a host to make network connections to that host and to hijack HTTP sessions using cookies stored in the browser. A vulnerability in the Java Runtime Environment (JRE) with applet classloading may allow an untrusted applet to read arbitrary files on a system that the applet runs on and make network connections to hosts other than the host it was loaded from. A buffer overflow vulnerability in the Java Runtime Environment (JRE) image processing code 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. Updated packages are available from download.opensuse.org.

1) Problem Description and Brief Discussion

  The IBM Java 1.4.2 JDK and JRE were brought to Service Release 13
  and the IBM JDK and JRE 6 were brought to Service Release 4.

  These updates fix lots of bugs and various security issues:

  CVE-2008-5350: A security vulnerability in the Java Runtime Environment
  (JRE) may allow an untrusted applet or application to list the contents
  of the home directory of the user running the applet or application.

  CVE-2008-5346: A security vulnerability in the Java Runtime Environment
  (JRE) with parsing zip files may allow an untrusted applet or
  application to read arbitrary memory locations in the process that
  the applet or application is running in.

  CVE-2008-5343: A vulnerability in Java Web Start and Java Plug-in may
  allow hidden code on a host to make network connections to that host
  and to hijack HTTP sessions using cookies stored in the browser.

  CVE-2008-5344: A vulnerability in the Java Runtime Environment
  (JRE) with applet classloading may allow an untrusted applet to read
  arbitrary files on a system that the applet runs on and make network
  connections to hosts other than the host it was loaded from.

  CVE-2008-5359: A buffer overflow vulnerability in the Java Runtime
  Environment (JRE) image processing code 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-2008-5339: A vulnerability in the Java Runtime Environment (JRE)
  may allow an untrusted Java Web Start application to make network
  connections to hosts other than the host that the application is
  downloaded from.

  CVE-2008-5340: A vulnerability in the Java Runtime Environment with
  launching Java Web Start applications 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-2008-5348: A security vulnerability in the Java Runtime Environment
  (JRE) with authenticating users through Kerberos may lead to a Denial
  of Service (DoS) to the system as a whole, due to excessive consumption
  of operating system resources.

  CVE-2008-2086: A vulnerability in Java Web Start may allow certain
  trusted operations to be performed, such as modifying system
  properties.

  CVE-2008-5345: The Java Runtime Environment (JRE) allows code loaded
  from the local filesystem to access localhost. This may allow code that
  is maliciously placed on the local filesystem and then subsequently
  run, to have network access to localhost that would not otherwise
  be allowed if the code were loaded from a remote host. This may be
  leveraged to steal cookies and hijack sessions (for domains that map
  a name to the localhost).

  CVE-2008-5351: The UTF-8 (Unicode Transformation Format-8) decoder in
  the Java Runtime Environment (JRE) accepts encodings that are longer
  than the "shortest" form. This behavior is not a vulnerability in Java
  SE. However, it may be leveraged to exploit systems running software
  that relies on the JRE UTF-8 decoder to reject non-shortest form
  sequences. For example, non-shortest form sequences may be decoded
  into illegal URIs, which may then allow files that are not otherwise
  accessible to be read, if the URIs are not checked following UTF-8
  decoding.

  CVE-2008-5360: The Java Runtime Environment creates temporary files
  with insufficiently random names. This may be leveraged to write JAR
  files which may then be loaded as untrusted applets and Java Web Start
  applications to access and provide services from localhost and hence
  steal cookies.

  CVE-2008-5353: A security vulnerability in the Java Runtime Environment
  (JRE) related to deserializing calendar objects 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-2008-5356: A buffer vulnerability in the Java Runtime Environment
  (JRE) 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-2008-5354: A buffer overflow vulnerability in the Java Runtime
  Environment (JRE) may allow an untrusted Java application that is
  launched through the command line to escalate privileges. For example,
  the untrusted Java application may grant itself permissions to read
  and write local files or execute local applications that are accessible
  to the user running the untrusted Java application.

  This vulnerability cannot be exploited by an applet or Java Web
  Start application.

  CVE-2008-5357: A buffer vulnerability in the Java Runtime Environment
  (JRE) 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-2008-5342: A security vulnerability in the the Java Web Start
  BasicService allows untrusted applications that are downloaded from
  another system to request local files to be displayed by the browser
  of the user running the untrusted application.

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 programs using 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.
