RHSA-2013:0605 - Critical: java-1.6.0-openjdk security update

Synopsis

Critical: java-1.6.0-openjdk security update

Type/Severity

Security Advisory Critical

Topic

Updated java-1.6.0-openjdk packages that fix two security issues are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having critical 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.

Description

These packages provide the OpenJDK 6 Java Runtime Environment and the OpenJDK 6 Software Development Kit.

An integer overflow flaw was found in the way the 2D component handled certain sample model instances. A specially-crafted sample model instance could cause Java Virtual Machine memory corruption and, possibly, lead to arbitrary code execution with virtual machine privileges. (CVE-2013-0809)

It was discovered that the 2D component did not properly reject certain malformed images. Specially-crafted raster parameters could cause Java Virtual Machine memory corruption and, possibly, lead to arbitrary code execution with virtual machine privileges. (CVE-2013-1493)

Note: If your system has not yet been upgraded to Red Hat Enterprise Linux 6.4 and the web browser plug-in provided by the icedtea-web package was installed, the issues exposed via Java applets could have been exploited without user interaction if a user visited a malicious website. Thus, this update has been rated as having critical security impact as a one time exception. The icedtea-web package as provided with Red Hat Enterprise Linux 6.4 uses OpenJDK 7 instead.

This erratum also upgrades the OpenJDK package to IcedTea6 1.11.9. Refer to the NEWS file, linked to in the References, for further information.

All users of java-1.6.0-openjdk are advised to upgrade to these updated packages, which resolve these issues. All running instances of OpenJDK Java must be restarted for the update to take effect.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258
