Original NVD Description

js/src/jstracer.cpp in the Just-in-time (JIT) JavaScript compiler (aka TraceMonkey) in Mozilla Firefox 3.5 before 3.5.1 allows remote attackers to execute arbitrary code via certain use of the escape function that triggers access to uninitialized memory locations, as originally demonstrated by a document containing P and FONT elements.
