For Firefox ESR versions prior to 128.4, update to version 128.4 or later. For Firefox ESR versions prior to 115.17, update to version 115.17 or later. For Thunderbird versions prior to 128.4, update to version 128.4 or later. For Thunderbird versions prior to 132, update to version 132 or later.

**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 107 Firefox ESR versions prior to 102.5 Thunderbird versions prior to 102.5 **Description** The issue is related to Service Workers in browsers, which could allow a remote attacker to infer information about the presence or length of a media file by exploiting timing information for cross-origin media combined with Range requests. **Recommendations** For Firefox versions prior to 107, update to version 107 or later. For Firefox ESR versions prior to 102.5, update to version 102.5 or later. For Thunderbird versions prior to 102.5, update to version 102.5 or later.

**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.

**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 72 **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 overflow error that could allow a remote attacker to access confidential data, compromise its integrity, and cause a denial of service. **Recommendations** For versions prior to 72, update to version 72 or later to resolve the issue. As a temporary workaround, consider restricting access to sensitive data and implementing additional security measures to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 71 Firefox ESR versions prior to 68.3 Thunderbird versions prior to 68.3 **Description** The issue is related to a memory safety bug that can be exploited by a remote attacker to access sensitive data, compromise data integrity, and cause a denial of service. The bug is associated with the lack of input size validation, allowing for potential memory corruption. It is presumed that with sufficient effort, some of these bugs could have been exploited to run arbitrary code. **Recommendations** For Firefox versions prior to 71, update to version 71 or later to resolve the issue. For Firefox ESR versions prior to 68.3, update to version 68.3 or later to resolve the issue. For Thunderbird versions prior to 68.3, update to version 68.3 or later to resolve the issue.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 62 Firefox ESR versions prior to 60.2 Thunderbird versions prior to 60.2.1 **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. This affects various versions of Firefox, Firefox ESR, and Thunderbird. **Recommendations** For Firefox versions prior to 62, update to version 62 or later. For Firefox ESR versions prior to 60.2, update to version 60.2 or later. For Thunderbird versions prior to 60.2.1, update to version 60.2.1 or later.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 59 **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 59, update to version 59 or later to resolve the issue. As a temporary workaround, consider restricting access to sensitive data until the update is applied.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 58 Firefox ESR versions prior to 52.6 Thunderbird versions prior to 52.6 **Description** The issue is related to memory safety bugs, including evidence of memory corruption, which could potentially be exploited to run arbitrary code. This is due to a buffer overflow in memory, allowing a remote attacker to execute arbitrary code. **Recommendations** For Firefox versions prior to 58, update to version 58 or later. For Firefox ESR versions prior to 52.6, update to version 52.6 or later. For Thunderbird versions prior to 52.6, update to version 52.6 or later.

**Name of the Vulnerable Software and Affected Versions** Mozilla Firefox versions prior to 47.0 Mozilla Firefox ESR versions prior to 45.2 **Description** The issue affects the browser engine, allowing remote attackers to cause a denial of service, which includes memory corruption and application crash, or possibly execute arbitrary code. The estimated number of potentially affected devices and details about real-world incidents are not specified. **Recommendations** For Mozilla Firefox versions prior to 47.0, update to version 47.0 or later. For Mozilla Firefox ESR versions prior to 45.2, update to version 45.2 or later.
