Details
The decoder for the FLC/FLI/FLX animation video formats in gst-plugins-good contains various out-of-bounds writes and reads and fails to initialize output frame memory.
Impact
If successful, a malicious third party could trigger either a crash in an application decoding a FLC/FLI/FLX video stream or an arbitrary code execution with the privileges of the target user. The failure to initialize output memory may result in an information leak.
Threat Mitigation
Exploitation requires the user to access an FLC/FLI/FLX stream or file.
Workarounds
The user should refrain from opening files from untrusted third parties or accessing untrusted remote sites, or disable the FLC/FLI/FLX decoder plugin by removing the plugin binary file libgstflxdec.so or libgstflxdec.dll.
Solution
The gst-plugins-bad 1.10.2 release addresses the issue. The upcoming gst-plugins-bad 1.8.4 release will also address the issue. People using older branches of GStreamer should apply the patch and recompile or disable the FLC/FLI/FLX plugin.
