Package : openjdk-6 Vulnerability : several Problem type : remote Debian-specific: no CVE ID : CVE-2010-4351 CVE-2010-4448 CVE-2010-4450 CVE-2010-4465 CVE-2010-4469 CVE-2010-4470 CVE-2010-4471 CVE-2010-4472 CVE-2011-0025 CVE-2011-0706

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.
