**Name of the Vulnerable Software and Affected Versions** Mozilla Firefox versions 3.0.x through 3.0.17 Mozilla Firefox versions 3.5.x through 3.5.7 SeaMonkey versions prior to 2.0.3 **Description** The issue is related to the Web Worker functionality, which does not properly handle array data types for posted messages. This can be exploited by remote attackers to cause a denial of service, resulting in heap memory corruption and application crash, or possibly execute arbitrary code. **Recommendations** For Mozilla Firefox versions 3.0.x through 3.0.17, update to version 3.0.18 or later. For Mozilla Firefox versions 3.5.x through 3.5.7, update to version 3.5.8 or later. For SeaMonkey versions prior to 2.0.3, update to version 2.0.3 or later.
