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 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** Firefox versions prior to 54 Firefox ESR versions prior to 52.2 Thunderbird versions prior to 52.2 **Description** The issue is related to memory safety bugs, including evidence of memory corruption, which could potentially be exploited to run arbitrary code.

For Firefox ESR versions prior to 52.2, update to version 52.2 or later. For Thunderbird versions prior to 52.2, update to version 52.2 or later.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 53 Firefox ESR versions prior to 45.9 Firefox ESR versions prior to 52.1 Thunderbird versions prior to 52.1 **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 53, update to version 53 or later. For Firefox ESR versions prior to 45.9, update to version 45.9 or later. For Firefox ESR versions prior to 52.1, update to version 52.1 or later. For Thunderbird versions prior to 52.1, update to version 52.1 or later.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 50 **Description** The issue allows a "<select>" dropdown menu to cover location bar content, potentially leading to spoofing attacks. This attack requires e10s to be enabled in order to function. **Recommendations** For versions prior to 50, update to version 50 or later to resolve the issue. As a temporary workaround, consider disabling e10s until a patch is available.

**Name of the Vulnerable Software and Affected Versions** Mozilla Firefox versions prior to 18.0 Firefox ESR versions prior to 10.0.12 and prior to 17.0.1 Thunderbird versions prior to 17.0.2 Thunderbird ESR versions prior to 10.0.12 and prior to 17.0.1 SeaMonkey versions prior to 2.15 **Description** The issue allows remote attackers to cause a denial of service, resulting in memory corruption and application crash, or possibly execute arbitrary code via unknown vectors. **Recommendations** For Mozilla Firefox versions prior to 18.0, update to version 18.0 or later. For Firefox ESR versions prior to 10.0.12, update to version 10.0.12 or later. For Firefox ESR versions prior to 17.0.1, update to version 17.0.1 or later.
