AV:N/AC:M/Au:N/C:P/I:P/A:P

Name of the Vulnerable Software and Affected Versions FFmpeg versions through 2.8.1 Google Chrome versions prior to 46.0.2490.71

Description The issue is related to the update dimensions function in libavcodec/vp8.c, which relies on a coefficient-partition count during multi-threaded operation. This allows remote attackers to cause a denial of service (race condition and memory corruption) or possibly have unspecified other impact via a crafted WebM file. The vulnerability is caused by synchronization errors when using a shared resource.

Recommendations For FFmpeg versions through 2.8.1, consider updating to a version that addresses the synchronization issue in the update dimensions function. For Google Chrome versions prior to 46.0.2490.71, update to version 46.0.2490.71 or later to resolve the issue. As a temporary workaround, consider disabling multi-threaded operation in FFmpeg until a patch is available.
