**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 77 Firefox ESR versions prior to 68.9 Thunderbird versions prior to 68.9.0 **Description** The issue is related to memory safety bugs and a buffer data boundary operation error. These bugs can lead to memory corruption, potentially allowing an attacker to run arbitrary code. The vulnerability may also enable a remote attacker to access confidential data, compromise data integrity, and cause a denial of service. **Recommendations** For Firefox versions prior to 77, update to version 77 or later. For Firefox ESR versions prior to 68.9, update to version 68.9 or later. For Thunderbird versions prior to 68.9.0, update to version 68.9.0 or later.
