IcedTea 1.7 before 1.7.8, 1.8 before 1.8.5, and 1.9 before 1.9.5 does not properly verify signatures for JAR files that (1) are "partially signed" or (2) signed by multiple entities, which allows remote attackers to trick users into executing code that appears to come from a trusted source.

The remote host is affected by the vulnerability described in GLSA-201406-32 (IcedTea JDK: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in the IcedTea JDK. Please       review the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could possibly execute arbitrary code with the       privileges of the process, cause a Denial of Service condition, obtain       sensitive information, bypass intended security policies, or have other       unspecified impact.
  Workaround :

    There is no known workaround at this time.

This update improves the signature handling of jar-files.
(CVE-2011-0025)

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.

Multiple vulnerabilities has been identified and fixed in java-1.6.0-openjdk :

The JNLP SecurityManager in IcedTea (IcedTea.so) 1.7 before 1.7.7, 1.8 before 1.8.4, and 1.9 before 1.9.4 for Java OpenJDK 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-2010-4351).

Additionally the java-1.5.0-gcj packages were not rebuilt with the shipped version on GCC for 2009.0 and Enterprise Server 5 which caused problems while building the java-1.6.0-openjdk updates, therefore rebuilt java-1.5.0-gcj packages are being provided with this advisory as well.

Packages for 2009.0 are provided as of the Extended Maintenance Program. Please visit this link to learn more:

The updated packages have been patched to correct this issue.

It was discovered that IcedTea for Java did not properly verify signatures when handling multiply signed or partially signed JAR files, allowing an attacker to cause code to execute that appeared to come from a verified source. (CVE-2011-0025)

USN 1052-1 fixed a vulnerability in OpenJDK for Ubuntu 9.10 and Ubuntu 10.04 LTS on all architectures, and Ubuntu 10.10 for all architectures except for the armel (ARM) architecture. This update provides the corresponding update for Ubuntu 10.10 on the armel (ARM) architecture.

It was discovered that the JNLP SecurityManager in IcedTea for Java OpenJDK in some instances failed to properly apply the intended scurity policy in its checkPermission method. This could allow an attacker to execute code with privileges that should have been prevented. (CVE-2010-4351).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
