- More information:
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 timers.
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.
