CVE-2015-0805: Canonical Ubuntu Linux

High severity, CVSS 7.5. EPSS: 3.6% chance of exploitation in the next 30 days.

The Off Main Thread Compositing (OMTC) implementation in Mozilla Firefox before 37.0 makes an incorrect memset call 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 and application crash) via vectors that trigger rendering of 2D graphics content.

• Canonical Ubuntu Linux: version 12.04 only; version 14.04 only; version 14.10 only
• Mozilla Firefox: up to and including 36.0.4
• Opensuse Opensuse: version 13.1 only; version 13.2 only
