**Name of the Vulnerable Software and Affected Versions** Thunderbird versions 140.10 through 150 Firefox versions 150 and earlier Firefox ESR versions 115.35 through 140.10 **Description** Memory safety bugs involving memory corruption could allow an attacker to run arbitrary code. **Recommendations** Update Thunderbird to version 151 or 140.11. Update Firefox to version 151. Update Firefox ESR to version 115.36 or 140.11.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 121 Firefox ESR versions prior to 115.6 Thunderbird versions prior to 115.6 **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 overflow in memory, which can allow a remote attacker to execute arbitrary code. **Recommendations** For Firefox versions prior to 121, update to version 121 or later. For Firefox ESR versions prior to 115.6, update to version 115.6 or later. For Thunderbird versions prior to 115.6, update to version 115.6 or later.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 108 Firefox ESR versions prior to 102.6 Thunderbird versions prior to 102.6 **Description** The issue is related to memory safety bugs and buffer overflow, which could potentially allow a remote attacker to access confidential data, compromise data integrity, and cause a denial of service. Some of these bugs showed evidence of memory corruption and it is presumed that with enough effort, some of these could have been exploited to run arbitrary code. **Recommendations** For Firefox versions prior to 108, update to version 108 or later. For Firefox ESR versions prior to 102.6, update to version 102.6 or later. For Thunderbird versions prior to 102.6, update to version 102.6 or later.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 94 Thunderbird versions prior to 91.3 Firefox ESR versions prior to 91.3 **Description** The issue is related to a buffer overflow in memory, which could allow a remote attacker to execute arbitrary code. Memory safety bugs were found in Firefox 93 and Firefox ESR 91.2, showing evidence of memory corruption. It is presumed that these bugs could be exploited with enough effort. **Recommendations** For Firefox versions prior to 94, update to version 94 or later. For Thunderbird versions prior to 91.3, update to version 91.3 or later. For Firefox ESR versions prior to 91.3, update to version 91.3 or later.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 90 Firefox ESR versions prior to 78.12 Thunderbird versions prior to 78.12 **Description** The issue is related to memory safety bugs present in code shared between Firefox and Thunderbird, which can lead to memory corruption. With sufficient effort, these bugs could potentially be exploited to run arbitrary code, allowing a remote attacker to access confidential data, compromise its integrity, and cause a denial of service. **Recommendations** For Firefox versions prior to 90, update to version 90 or later. For Firefox ESR versions prior to 78.12, update to version 78.12 or later. For Thunderbird versions prior to 78.12, update to version 78.12 or later.

Name of the Vulnerable Software and Affected Versions: Firefox versions prior to 86 Description: Mozilla developers reported memory safety bugs present in Firefox 85, showing evidence of memory corruption. It is presumed that with enough effort, some of these bugs could have been exploited to run arbitrary code. Recommendations: For versions prior to 86, update to version 86 or later to resolve the issue.
