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)

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.
