Please Install the Updated Packages.

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.

java-1.6.0-openjdk on Red Hat Enterprise Linux Desktop (v. 6), Red Hat Enterprise Linux Server (v. 6), Red Hat Enterprise Linux Workstation (v. 6)
