Ubuntu Security Notice 3135-2 – USN-3135-1 fixed a vulnerability in GStreamer Good Plugins. The original security fix was incomplete. This update fixes the problem. Chris Evans discovered that GStreamer Good Plugins did not correctly handle malformed FLC movie files. If a user were tricked into opening a crafted FLC movie file with a GStreamer application, an attacker could cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking the program. Various other issues were also addressed.
