USN-3135-1 fixed a vulnerability in GStreamer Good Plugins. The original security fix was incomplete. This update fixes the problem.
Original advisory details:
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.
