Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

USN-1755-1 fixed vulnerabilities in OpenJDK 6. This update provides
the corresponding updates for OpenJDK 7.

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).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
