Description

The texSubImage2D implementation in the WebGL subsystem in Google Chrome before 20.0.1132.43 does not properly handle uploads to floating-point textures, which allows remote attackers to cause a denial of service (assertion failure and application crash) or possibly have unspecified other impact via a crafted web page, as demonstrated by certain WebGL performance tests, aka rdar problem 11520387.

Affected products

Google Chrome: through 20.0.1132.42; 20.0.1132.0, 20.0.1132.1, 20.0.1132.2, 20.0.1132.3, 20.0.1132.4, 20.0.1132.5 (+36)
