CVE-2013-1055 Information

Description

The unity-firefox-extension package could be tricked into dropping a C callback which was still in use which Firefox would then free causing Firefox to crash. This could be achieved by adding an action to the launcher and updating it with new callbacks until the libunity-webapps rate limit was hit. Fixed in 3.0.0+14.04.20140416-0ubuntu1.14.04.1 of unity-firefox-extension and in all versions of libunity-webapps by shipping an empty unity-firefox-extension package thus disabling the extension entirely and invalidating the attack against the libunity-webapps package.
