**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 85 Firefox ESR versions prior to 78.7 Thunderbird versions prior to 78.7 **Description** The issue is related to 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 vulnerability in memory, allowing a remote attacker to execute arbitrary code. **Recommendations** For Firefox versions prior to 85, update to version 85 or later. For Firefox ESR versions prior to 78.7, update to version 78.7 or later. For Thunderbird versions prior to 78.7, update to version 78.7 or later.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 83 Firefox ESR versions prior to 78.5 Thunderbird versions prior to 78.5 **Description** The issue is related to memory safety bugs present in certain versions of Firefox, Firefox ESR, and Thunderbird. These bugs have shown evidence of memory corruption, and it is presumed that with sufficient effort, some of these could be exploited to run arbitrary code. **Recommendations** For Firefox versions prior to 83, update to version 83 or later. For Firefox ESR versions prior to 78.5, update to version 78.5 or later. For Thunderbird versions prior to 78.5, update to version 78.5 or later.

Name of the Vulnerable Software and Affected Versions: Firefox versions prior to 81 Description: The issue is related to a buffer overflow in memory, which can be exploited by a remote attacker to execute arbitrary code. It is associated with memory safety bugs that showed evidence of memory corruption. Recommendations: For versions prior to 81, update to version 81 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** Firefox versions prior to 80 Firefox ESR versions prior to 78.2 Thunderbird versions prior to 78.2 Firefox for Android versions prior to 80 **Description** The issue is related to memory safety bugs and buffer overflow in memory, which could potentially be exploited to run arbitrary code. This can be achieved by a remote attacker using a specially crafted web page. **Recommendations** For Firefox versions prior to 80, update to version 80 or later. For Firefox ESR versions prior to 78.2, update to version 78.2 or later. For Thunderbird versions prior to 78.2, update to version 78.2 or later. For Firefox for Android versions prior to 80, update to version 80 or later.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 78 Firefox ESR versions prior to 68.10 Thunderbird versions prior to 68.10.0 **Description** A race condition could cause a use-after-free of a pointer when trying to connect to a STUN server, leading to memory corruption and a potentially exploitable crash. This issue may allow a remote attacker to access confidential data, compromise data integrity, and cause a denial of service. **Recommendations** For Firefox versions prior to 78, update to version 78 or later. For Firefox ESR versions prior to 68.10, update to version 68.10 or later. For Thunderbird versions prior to 68.10.0, update to version 68.10.0 or later.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 74 Firefox ESR versions prior to 68.6 Thunderbird versions prior to 68.6 **Description** Memory safety bugs have been reported in Firefox and Thunderbird, with evidence of memory corruption. It is presumed that these bugs could be exploited to run arbitrary code with sufficient effort. **Recommendations** For Firefox versions prior to 74, update to version 74 or later. For Firefox ESR versions prior to 68.6, update to version 68.6 or later. For Thunderbird versions prior to 68.6, update to version 68.6 or later.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 70 Firefox ESR versions prior to 68.2 Thunderbird versions prior to 68.2 **Description** The issue is related to memory safety bugs, including evidence of memory corruption, which could potentially be exploited to run arbitrary code. This could allow a remote attacker to access confidential data, compromise its integrity, and cause a denial of service. The estimated number of potentially affected devices worldwide is not specified. **Recommendations** For Firefox versions prior to 70, update to version 70 or later. For Firefox ESR versions prior to 68.2, update to version 68.2 or later. For Thunderbird versions prior to 68.2, update to version 68.2 or later.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 57 **Description** The issue is related to a buffer data boundary operation overflow. It may allow a remote attacker to execute arbitrary code. Memory safety bugs were reported, showing evidence of memory corruption, which could potentially be exploited. **Recommendations** For versions prior to 57, update to version 57 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 54 ALT Linux (affected versions not specified) **Description** Memory safety bugs were reported, showing evidence of memory corruption. It is presumed that with enough effort, some of these bugs could be exploited to run arbitrary code. **Recommendations** For Firefox versions prior to 54, update to version 54 or later to resolve the issue. At the moment, there is no information about a fix for ALT Linux.

**Name of the Vulnerable Software and Affected Versions** Mozilla Firefox versions prior to 49.0 Mozilla Firefox ESR 45.x versions prior to 45.4 Thunderbird versions prior to 45.4 **Description** The issue affects the browser engine, allowing remote attackers to cause a denial of service, which may result in memory corruption and application crash, or possibly execute arbitrary code via unknown vectors. **Recommendations** For Mozilla Firefox versions prior to 49.0, update to version 49.0 or later. For Mozilla Firefox ESR 45.x versions prior to 45.4, update to version 45.4 or later. For Thunderbird versions prior to 45.4, update to version 45.4 or later.

**Name of the Vulnerable Software and Affected Versions** Mozilla Firefox versions prior to 40.0 **Description** The issue is due to insufficient input validation, allowing remote attackers to potentially execute arbitrary code or cause a denial of service, which may result in memory corruption and application crash. The estimated number of potentially affected devices and details about real-world incidents are not provided. **Recommendations** For versions prior to 40.0, update to version 40.0 or later to resolve the issue. As a temporary workaround, consider restricting access to untrusted websites and avoiding suspicious links to minimize the risk of exploitation.
