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

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.
