**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 66 **Description** The issue is related to memory safety bugs, including evidence of memory corruption, which could potentially be exploited to run arbitrary code. It is also described as a buffer overflow vulnerability in memory, allowing a remote attacker to access confidential data, compromise its integrity, and cause a denial of service. **Recommendations** For versions prior to 66, update to version 66 or later to resolve the issue. As a temporary workaround, consider restricting access to sensitive data and minimizing browser usage until the update is applied.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 52 Thunderbird versions prior to 52 **Description** Memory safety bugs were reported, showing evidence of memory corruption. It is presumed that with enough effort, some of these bugs could be exploited to run arbitrary code. **Recommendations** For Firefox versions prior to 52, update to version 52 or later. For Thunderbird versions prior to 52, update to version 52 or later.
