Ubuntu 12.10 : unity-firefox-extension vulnerability (USN-1639-1)

High Nessus Plugin ID 63027


The remote Ubuntu host is missing a security-related patch.


It was discovered that unity-firefox-extension incorrectly handled certain callbacks. A remote attacker could use this issue to cause unity-firefox-extension to crash, resulting in a denial of service, or possibly execute arbitrary code.

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 xul-ext-unity package.
