Description

jslock.cpp in Mozilla Firefox 3.x before 3.0.2, Firefox 2.x before 2.0.0.18, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by modifying the window.__proto__.__proto__ object in a way that causes a lock on a non-native object, which triggers an assertion failure related to the OBJ_IS_NATIVE function.

Affected configurations

• mozilla firefox (>= 2.0 < 2.0.0.18) • mozilla firefox (>= 3.0 < 3.0.2) • mozilla seamonkey (>= 1.0 < 1.1.13) • mozilla thunderbird (>= 2.0 < 2.0.0.18) • debian debian linux 4.0 • canonical ubuntu linux 6.06 • canonical ubuntu linux 7.10 • canonical ubuntu linux 8.04 • canonical ubuntu linux 8.10
