Mozilla Firefox, Thunderbird and SeaMonkey contain a flaw related to the line-breaking implementation's handling of long strings. The issue is triggered when a context-dependent attacker uses a maliciously crafted document.write call to trigger a buffer over-read. This will allow the execution of arbitrary code.
