**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 89 Firefox ESR versions prior to 78.11 Thunderbird versions prior to 78.11 **Description** The issue is related to a memory buffer overflow, which can be exploited by a remote attacker to execute arbitrary code by creating a malicious web page. Some memory safety bugs have shown evidence of memory corruption, and it is presumed that these could be exploited to run arbitrary code with sufficient effort. **Recommendations** For Firefox versions prior to 89, update to version 89 or later to resolve the issue. For Firefox ESR versions prior to 78.11, update to version 78.11 or later to resolve the issue. For Thunderbird versions prior to 78.11, update to version 78.11 or later to resolve the issue.

**Name of the Vulnerable Software and Affected Versions** Firefox ESR versions 68.7 through 68.7 Firefox versions 75 through 75 Thunderbird versions prior to 68.8.0 **Description** The issue is related to memory safety bugs, which can lead to memory corruption. With sufficient effort, these bugs could potentially be exploited to run arbitrary code. The vulnerability is also described as a buffer overflow in memory, which could allow a remote attacker to cause a denial of service. **Recommendations** For Firefox ESR version 68.7, update to version 68.8 or later. For Firefox version 75, update to version 76 or later. For Thunderbird versions prior to 68.8.0, update to version 68.8.0 or later.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 75 **Description** The issue is related to memory safety bugs, which have been identified in Firefox. These bugs have shown evidence of memory corruption, and it is presumed that they could be exploited to run arbitrary code with sufficient effort. **Recommendations** For versions prior to 75, update to version 75 or later to resolve the issue.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 74 **Description** The issue is related to memory safety and script safety bugs in Firefox, which could potentially lead to memory corruption or escalation of privilege. 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 could allow a remote attacker to execute arbitrary code. **Recommendations** For versions prior to 74, update to version 74 or later to resolve the issue. As a temporary workaround, consider restricting access to sensitive resources until the update is applied.

**Name of the Vulnerable Software and Affected Versions** Google Chrome versions prior to 79.0.3945.79 **Description** The issue is related to an inappropriate implementation in WebRTC, allowing a remote attacker to potentially exploit heap corruption via a crafted HTML page. This could enable the attacker to impact the system. **Recommendations** For versions prior to 79.0.3945.79, update to version 79.0.3945.79 or later to resolve the issue.
