Buffer overflow vulnerability in Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, Mozilla Thunderbird before 3.0.11 and 3.1.x before 3.1.7 and Mozilla SeaMonkey before 2.0.11
Description:
The line-breaking implementation in Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, Thunderbird before 3.0.11 and 3.1.x before 3.1.7, and SeaMonkey before 2.0.11 on Windows does not properly handle long strings, which allows remote attackers to execute arbitrary code via a crafted document.write call that triggers a buffer over-read.
