CVE-2021-23965 1 Mozilla 1 Firefox 2024-02-28 6.8 MEDIUM 8.8 HIGH
Mozilla developers reported memory safety bugs present in Firefox 84. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 85.
CVE-2020-26950 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-02-28 9.3 HIGH 8.8 HIGH
In certain circumstances, the MCallGetProperty opcode can be emitted with unmet assumptions resulting in an exploitable use-after-free condition. This vulnerability affects Firefox < 82.0.3, Firefox ESR < 78.4.1, and Thunderbird < 78.4.2.
CVE-2020-26963 1 Mozilla 1 Firefox 2024-02-28 4.3 MEDIUM 4.3 MEDIUM

Other operating systems are unaffected.*. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6.
CVE-2020-15684 1 Mozilla 1 Firefox 2024-02-28 7.5 HIGH 9.8 CRITICAL
Mozilla developers reported memory safety bugs present in Firefox 81. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 82.
CVE-2021-23961 2 Debian, Mozilla 2 Debian Linux, Firefox 2024-02-28 4.3 MEDIUM 7.4 HIGH
Further techniques that built on the slipstream research combined with a malicious webpage could have exposed both an internal network's hosts as well as services running on the user's local machine. This vulnerability affects Firefox < 85.

CVE-2021-23963 1 Mozilla 1 Firefox 2024-02-28 4.3 MEDIUM 4.3 MEDIUM

In Network Security Services before 3.44, a malformed Netscape Certificate Sequence can cause NSS to crash, resulting in a denial of service.
CVE-2021-23957 1 Mozilla 1 Firefox 2024-02-28 4.3 MEDIUM 7.4 HIGH
Navigations through the Android-specific `intent` URL scheme could have been misused to escape iframe sandbox. Note: This issue only affected Firefox for Android. Other operating systems are unaffected. This vulnerability affects Firefox < 85.
CVE-2020-15682 1 Mozilla 1 Firefox 2024-02-28 4.3 MEDIUM 6.5 MEDIUM
When a link to an external protocol was clicked, a prompt was presented that allowed the user to choose what application to open it in. An attacker could induce that prompt to be associated with an origin they didn't control, resulting in a spoofing attack. This was fixed by changing external protocol prompts to be tab-modal while also ensuring they could not be incorrectly associated with a different origin. This vulnerability affects Firefox < 82.
CVE-2020-15667 1 Mozilla 1 Firefox 2024-02-28 6.8 MEDIUM 8.8 HIGH
When processing a MAR update file, after the signature has been validated, an invalid name length could result in a heap overflow, leading to memory corruption and potentially arbitrary code execution. Within Firefox as released by Mozilla, this issue is only exploitable with the Mozilla-controlled signing key. This vulnerability affects Firefox < 80.
