CVE-2015-6761 is a vulnerability of currently unknown severity. The update_dimensions function in libavcodec/vp8.c in FFmpeg through 2.8.1, as used in Google Chrome before 46.0.2490.71 and other products, relies on a coefficient-partition count during multi-threaded operation, which 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.. EPSS estimates a 1.05% chance of exploitation in the next 30 days.
