An attacker was able to inject an event handler into a privileged object that would allow arbitrary JavaScript execution in the parent process. Note: This vulnerability affects Desktop Firefox only, it does not affect mobile versions of Firefox. This...

A missing delay on when pointer lock was used could have allowed a malicious page to trick a user into granting permissions. This vulnerability affects Firefox < 124, Firefox ESR < 115.9, and Thunderbird < 115.9.

If an attacker could find a way to trigger a particular code path in `SafeRefPtr`, it could have triggered a crash or potentially be leveraged to achieve code execution. This vulnerability affects Firefox < 124, Firefox ESR < 115.9, and Thunderbird <...

Data was not properly sanitized when decoding a QUIC ACK frame; this could have led to unrestricted memory consumption and a crash. This vulnerability affects Firefox < 124.

Memory safety bugs present in Firefox 123, Firefox ESR 115.8, and Thunderbird 115.8. 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 vu...

Memory safety bugs present in Firefox 123. 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 < 124.

To harden ICU against exploitation, the behavior for out-of-memory conditions was changed to crash instead of attempt to continue. This vulnerability affects Firefox ESR < 115.9 and Thunderbird < 115.9.

An attacker could have leveraged the Windows Error Reporter to run arbitrary code on the system escaping the sandbox. *Note:* This issue only affected Windows operating systems. Other operating systems are unaffected. This vulnerability affects Firef...

Passing invalid data could have led to invalid wasm values being created, such as arbitrary integers turning into pointer values. This vulnerability affects Firefox < 124.

Return registers were overwritten which could have allowed an attacker to execute arbitrary code. *Note:* This issue only affected Armv7-A systems. Other operating systems are unaffected. This vulnerability affects Firefox < 124, Firefox ESR < 115.9,...
