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.

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 of java-1_6_0-openjdk improves the return value handling of JNLPSecurityManager. Prior to this update the JNLPSecurityManager silently returns in some cases when a permission was denied.
(CVE-2010-4351) Additionally the java path was fixed to make java work with firefox again.

The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2011-0176 advisory.

    [1:1.6.0.0-1.17.b17.0.1.el5]
    - Add oracle-enterprise.patch

    [1:1.6.0.0-1.17.b17.el5]
    - Updated to 1.7.7 tarball
    - Resolves: bz668487
    - Also resolves bz668488

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

A public static field declaration allowed untrusted JNLP (Java Network Launching Protocol) applications to read privileged data. A remote attacker could directly or indirectly read the values of restricted system properties, such as 'user.name', 'user.home', and 'java.home', which untrusted applications should not be allowed to read.
(CVE-2010-3860)

It was found that JNLPSecurityManager could silently return without throwing an exception when permission was denied. If the javaws command was used to launch a Java Web Start application that relies on this exception being thrown, it could result in that application being run with elevated privileges, allowing it to bypass security manager restrictions and gain access to privileged functionality.
(CVE-2010-4351)

Note: The previous java-1.6.0-openjdk update installed javaws by mistake. As part of the fixes for CVE-2010-3860 and CVE-2010-4351, this update removes javaws.

This erratum also upgrades the OpenJDK package to IcedTea6 1.7.7.
Refer to the NEWS file, linked to in the References, for further information.

All running instances of OpenJDK Java must be restarted for the update to take effect.

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.

Updated java-1.6.0-openjdk packages that fix two security issues are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

These packages provide the OpenJDK 6 Java Runtime Environment and the OpenJDK 6 Software Development Kit. The javaws command can be used to launch Java Web Start applications.
