The class file parser in IBM Java before 1.4.2 SR13 FP9, as used in IBM Runtimes for Java Technology 5.0.0 before SR13 and 6.0.0 before SR10, allows remote authenticated users to cause a denial of service (JVM segmentation fault, and possibly memory consumption or an infinite loop) via a crafted attribute length field in a class file, which triggers a buffer over-read.

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2011:1265 advisory.

  - IBM JDK Class file parsing denial-of-service (CVE-2011-0311)

  - Oracle/IBM JDK: unspecified vulnerabilities fixed in 6u26 (Sound) (CVE-2011-0802, CVE-2011-0814)

  - OpenJDK: integer overflows in JPEGImageReader and font SunLayoutEngine (2D, 7013519) (CVE-2011-0862)

  - OpenJDK: Deserialization allows creation of mutable SignedObject (Deserialization, 6618658)     (CVE-2011-0865)

  - OpenJDK: NetworkInterface information leak (Networking, 7013969) (CVE-2011-0867)

  - OpenJDK: MediaTracker created Component instances with unnecessary privileges (Swing, 7020198)     (CVE-2011-0871)

  - java-1.4.2-ibm: DoS via class file parser in IBM Java 1.4.2.SR13.FP9 (CVE-2011-3387)

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

IBM Java 1.4.2 was updated to SR13 FP9, fixing bugs and security issues.

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2011:1159 advisory.

    The IBM 1.4.2 SR13-FP10 Java release includes the IBM Java 2 Runtime     Environment and the IBM Java 2 Software Development Kit.

    This update fixes several vulnerabilities in the IBM Java 2 Runtime     Environment and the IBM Java 2 Software Development Kit. Detailed     vulnerability descriptions are linked from the IBM Security alerts page,     listed in the References section. (CVE-2011-0311, CVE-2011-0802,     CVE-2011-0814, CVE-2011-0862, CVE-2011-0865, CVE-2011-0867, CVE-2011-0871)

    Note: The RHSA-2011:0490 java-1.4.2-ibm update did not, unlike the erratum     text stated, provide a complete fix for the CVE-2011-0311 issue.

    All users of java-1.4.2-ibm are advised to upgrade to these updated     packages, which contain the IBM 1.4.2 SR13-FP10 Java release. All running     instances of IBM Java must be restarted for this update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise 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.
