Critical Nessus Plugin ID 65095


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


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).

Note that Tenable Network Security has extracted the preceding 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.


Update the affected packages.
