openjdk-6 - several

Several security vulnerabilities were discovered in OpenJDK, an
implementation of the Java platform.

• CVE-2010-4351
  The JNLP SecurityManager returns from the checkPermission method
  instead of throwing an exception in certain circumstances, which
  might allow context-dependent attackers to bypass the intended
  security policy by creating instances of ClassLoader.
• CVE-2010-4448
  Malicious applets can perform DNS cache poisoning.
• CVE-2010-4450
  An empty (but set) LD_LIBRARY_PATH environment variable results in
  a misconstructed library search path, resulting in code execution
  from possibly untrusted sources.
• CVE-2010-4465
  Malicious applets can extend their privileges by abusing Swing
  timers.
• CVE-2010-4469
  The Hotspot just-in-time compiler miscompiles crafted byte
  sequences, resulting in heap corruption.
• CVE-2010-4470
  JAXP can be exploited by untrusted code to elevate privileges.
• CVE-2010-4471
  Java2D can be exploited by untrusted code to elevate privileges.
• CVE-2010-4472
  Untrusted code can replace the XML DSIG implementation.
• CVE-2011-0025
  Signatures on JAR files are not properly verified, which allows
  remote attackers to trick users into executing code that appears
  to come from a trusted source.
• CVE-2011-0706
  The JNLPClassLoader class allows remote attackers to gain
  privileges via unknown vectors related to multiple signers and the
  assignment of an inappropriate security descriptor.

In addition, this security update contains stability fixes, such as
switching to the recommended Hotspot version (hs14) for this
particular version of OpenJDK.

For the oldstable distribution (lenny), these problems have been fixed in
version 6b18-1.8.7-2~lenny1.

For the stable distribution (squeeze), these problems have been fixed in
version 6b18-1.8.7-2~squeeze1.

For the testing distribution (wheezy) and the unstable distribution
(sid), these problems have been fixed in version 1.8.7-1.

We recommend that you upgrade your openjdk-6 packages.
