Original advisory details:

It was discovered that OpenJDK did not properly validate certain types
of images. A remote attacker could exploit this to cause OpenJDK to crash.
(CVE-2013-0809)

It was discovered that OpenJDK did not properly check return values when
performing color conversion for images. If a user were tricked into
opening a crafted image with OpenJDK, such as with the Java plugin, a
remote attacker could cause OpenJDK to crash or execute arbitrary code
outside of the Java sandbox with the privileges of the user invoking the
program. (CVE-2013-1493)
