**Name of the Vulnerable Software and Affected Versions** Thunderbird version 150 Firefox version 150 **Description** Memory safety bugs involving memory corruption may allow an attacker to execute arbitrary code. **Recommendations** Update Thunderbird to version 151. Update Firefox to version 151.

**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.
