**Name of the Vulnerable Software and Affected Versions** Firefox version 150.0.1 **Description** Memory safety bugs exist that exhibit evidence of memory corruption. These issues could potentially be exploited to execute arbitrary code. **Recommendations** Update to version 150.0.2.

**Name of the Vulnerable Software and Affected Versions** Firefox ESR version 140.9 Thunderbird ESR version 140.9 Firefox version 149 Thunderbird version 149 **Description** Memory safety bugs involving memory corruption could allow an attacker to run arbitrary code. **Recommendations** Update Firefox ESR to version 140.10. Update Thunderbird ESR to version 140.10. Update Firefox to version 150. Update Thunderbird to version 150.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 67 Firefox ESR versions prior to 60.7 Thunderbird versions prior to 60.7 **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 data boundary operation issue, which can allow a remote attacker to cause a denial of service and disrupt data integrity. **Recommendations** For Firefox versions prior to 67, update to version 67 or later. For Firefox ESR versions prior to 60.7, update to version 60.7 or later. For Thunderbird versions prior to 60.7, update to version 60.7 or later.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 67 **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 vulnerability in memory, allowing a remote attacker to access confidential data, compromise its integrity, and cause a denial of service. **Recommendations** For versions prior to 67, update to version 67 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 64 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 vulnerability in memory, allowing a remote attacker to access confidential data, compromise its integrity, and cause a denial of service. Recommendations: For versions prior to 64, update to version 64 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 57 Firefox ESR versions prior to 52.5 Thunderbird versions prior to 52.5 **Description** The issue is related to a buffer overflow in memory, which can be exploited by a remote attacker to execute arbitrary code. This is due to memory safety bugs that have been reported, some of which show evidence of memory corruption. It is presumed that with sufficient effort, these bugs could be exploited to run arbitrary code. **Recommendations** For Firefox versions prior to 57, update to version 57 or later. For Firefox ESR versions prior to 52.5, update to version 52.5 or later. For Thunderbird versions prior to 52.5, update to version 52.5 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 56 Firefox ESR versions prior to 52.4 Thunderbird versions prior to 52.4 **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 56, update to version 56 or later. For Firefox ESR versions prior to 52.4, update to version 52.4 or later. For Thunderbird versions prior to 52.4, update to version 52.4 or later.

**Name of the Vulnerable Software and Affected Versions** Firefox versions 50.1 and earlier Firefox ESR versions 45.6 and earlier Thunderbird versions prior to 45.7 **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 50.1 and earlier, update to version 51 or later. For Firefox ESR versions 45.6 and earlier, update to version 45.7 or later. For Thunderbird versions prior to 45.7, update to version 45.7 or later.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 51 **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 versions prior to 51, update to version 51 or later to resolve the issue.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 50.1 Firefox ESR versions prior to 45.6 Thunderbird versions prior to 45.6 **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 50.1, update to version 50.1 or later. For Firefox ESR versions prior to 45.6, update to version 45.6 or later. For Thunderbird versions prior to 45.6, update to version 45.6 or later.

**Name of the Vulnerable Software and Affected Versions** Mozilla Firefox versions prior to 36.0 **Description** The issue is related to the improper restriction of transitions of JavaScript objects from a non-extensible state to an extensible state. This allows remote attackers to bypass sandbox protection mechanisms via a crafted web site. **Recommendations** For versions prior to 36.0, update to version 36.0 or later to resolve the issue.

**Name of the Vulnerable Software and Affected Versions** Mozilla Firefox versions prior to 36.0 Mozilla Firefox ESR versions 31.x prior to 31.5 Thunderbird versions prior to 31.5 **Description** The issue is related to multiple unspecified vulnerabilities in the browser engine, allowing remote attackers to cause a denial of service, which includes memory corruption and application crash, or possibly execute arbitrary code via unknown vectors. **Recommendations** For Mozilla Firefox versions prior to 36.0, update to version 36.0 or later. For Mozilla Firefox ESR versions 31.x prior to 31.5, update to version 31.5 or later. For Thunderbird versions prior to 31.5, update to version 31.5 or later.
