CVE-2015-4512: Mozilla Firefox

Medium severity, CVSS 6.4. EPSS: 3.5% chance of exploitation in the next 30 days.

gfx/2d/DataSurfaceHelpers.cpp in Mozilla Firefox before 41.0 on Linux improperly attempts to use the Cairo library with 32-bit color-depth surface creation followed by 16-bit color-depth surface display, which allows remote attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read) by using a CANVAS element to trigger 2D rendering.

Affected products

• Mozilla Firefox: up to and including 40.0.3
