**Name of the Vulnerable Software and Affected Versions** Mozilla Firefox versions prior to 3.5.16 Mozilla Firefox versions 3.6.x prior to 3.6.13 Thunderbird versions prior to 3.0.11 Thunderbird versions 3.1.x prior to 3.1.7 SeaMonkey versions prior to 2.0.11 **Description** The issue arises from the improper handling of long strings by the line-breaking implementation, allowing remote attackers to execute arbitrary code. This can be achieved through a crafted document.write call that triggers a buffer over-read. **Recommendations** For Mozilla Firefox versions prior to 3.5.16, update to version 3.5.16 or later. For Mozilla Firefox versions 3.6.x prior to 3.6.13, update to version 3.6.13 or later. For Thunderbird versions prior to 3.0.11, update to version 3.0.11 or later. For Thunderbird versions 3.1.x prior to 3.1.7, update to version 3.1.7 or later. For SeaMonkey versions prior to 2.0.11, update to version 2.0.11 or later.
