**Name of the Vulnerable Software and Affected Versions** Mozilla Firefox versions prior to 3.6.18 Thunderbird versions prior to 3.1.11 **Description** The issue is related to multiple unspecified vulnerabilities in the browser engine, allowing remote attackers to cause a denial of service, which includes memory corruption and application crash, or possibly execute arbitrary code via unknown vectors. **Recommendations** For Mozilla Firefox versions prior to 3.6.18, update to version 3.6.18 or later.

**Name of the Vulnerable Software and Affected Versions** Mozilla Firefox versions prior to 3.5.7 **Description** The issue allows remote attackers to cause a denial of service, resulting in an application crash.

**Name of the Vulnerable Software and Affected Versions** Mozilla Firefox versions 3.5.x through 3.5.1 **Description** The issue allows remote attackers to cause a denial of service, resulting in memory corruption and application crash, or possibly execute arbitrary code. This is related to the `TraceRecorder::snapshot` function in `js/src/jstracer.cpp` and other unspecified vectors. **Recommendations** For Mozilla Firefox versions 3.5.x through 3.5.1, update to version 3.5.2 or later to resolve the issue.
