Description

The Off Main Thread Compositing (OMTC) implementation in Mozilla Firefox before 37.0 attempts to use memset for a memory region of negative length during interaction with the mozilla::layers::BufferTextureClient::AllocateForSurface function, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via vectors that trigger rendering of 2D graphics content.
