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

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.

Malicious applets can perform DNS cache poisoning.

An empty (but set) LD_LIBRARY_PATH environment variable results in
a misconstructed library search path, resulting in code execution
from possibly untrusted sources.

Malicious applets can extend their privileges by abusing Swing

The Hotspot just-in-time compiler miscompiles crafted byte
sequences, resulting in heap corruption.

JAXP can be exploited by untrusted code to elevate privileges.

Java2D can be exploited by untrusted code to elevate privileges.

Untrusted code can replace the XML DSIG implementation.

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.

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.
