**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 73 Firefox ESR versions prior to 68.5 Thunderbird versions prior to 68.5 **Description** The issue is related to memory safety bugs that can cause memory corruption. It is presumed that these bugs could be exploited to run arbitrary code with sufficient effort. These flaws are potentially risky in browser or browser-like contexts, but they cannot be exploited through email in the Thunderbird product due to disabled scripting when reading mail. **Recommendations** For Firefox versions prior to 73, update to version 73 or later. For Firefox ESR versions prior to 68.5, update to version 68.5 or later. For Thunderbird versions prior to 68.5, update to version 68.5 or later.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 68 **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 data boundary operation vulnerability, where exploitation could allow a remote attacker to execute arbitrary code. **Recommendations** For versions prior to 68, update to version 68 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 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.
