Memory corruption

Mozilla developers Kershaw Chang and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 109 and Firefox ESR 102.7. 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. Thi...

Spoofing

A background script invoking requestFullscreen and then blocking the main thread could force the browser into fullscreen mode indefinitely, resulting in potential user confusion or spoofing attacks. This vulnerability affects Firefox 110, Thunderbird 102.8, and Firefox ESR 102.8...

Memory corruption

Memory safety bugs present in Firefox 112 and Firefox ESR 102.10. 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 113, Firefox ESR 102.11, and Thunderbi...

Code injection

A type checking bug would have led to invalid code being compiled. This vulnerability affects Firefox 113, Firefox ESR 102.11, and Thunderbird 102.11...
