**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 82 **Description** The issue is related to memory safety bugs that were reported by Mozilla developers in Firefox 81, some of which showed evidence of memory corruption. It is presumed that with sufficient effort, some of these bugs could have been exploited to run arbitrary code. **Recommendations** For versions prior to 82, update to version 82 or later to resolve the issue.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 67 Firefox ESR versions prior to 60.7 Thunderbird versions prior to 60.7 **Description** The issue is related to memory safety bugs, which can lead to memory corruption. It is presumed that with sufficient effort, some of these bugs could be exploited to run arbitrary code. The vulnerability is also described as a buffer data boundary operation issue, which can allow a remote attacker to cause a denial of service and disrupt data integrity. **Recommendations** For Firefox versions prior to 67, update to version 67 or later. For Firefox ESR versions prior to 60.7, update to version 60.7 or later. For Thunderbird versions prior to 60.7, update to version 60.7 or later.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 63 Firefox ESR versions prior to 60.3 Thunderbird versions prior to 60.3 **Description** The issue is caused by memory safety bugs, including evidence of memory corruption, which could potentially be exploited to run arbitrary code with enough effort. It is also described as a buffer overflow in memory, allowing a remote attacker to execute arbitrary code. **Recommendations** For Firefox versions prior to 63, update to version 63 or later. For Firefox ESR versions prior to 60.3, update to version 60.3 or later. For Thunderbird versions prior to 60.3, update to version 60.3 or later.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 62 Firefox ESR versions prior to 60.2 Thunderbird versions prior to 60.2.1 **Description** The issue is caused by memory safety bugs, including evidence of memory corruption, which could potentially be exploited to run arbitrary code with enough effort. This affects various versions of Firefox, Firefox ESR, and Thunderbird. **Recommendations** For Firefox versions prior to 62, update to version 62 or later. For Firefox ESR versions prior to 60.2, update to version 60.2 or later. For Thunderbird versions prior to 60.2.1, update to version 60.2.1 or later.
