Mozilla developers and community members Lukas Bernhard, Gabriele Svelto, Randell Jesup, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 107. 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 < 108.

USN-5782-1 fixed vulnerabilities in Firefox. The update introduced
several minor regressions. This update fixes the problem.
We apologize for the inconvenience.
Original advisory details:
It was discovered that Firefox was using an out-of-date libusrsctp library.
An attacker could possibly use this library to perform a reentrancy issue
on Firefox. (CVE-2022-46871)
Nika Layzell discovered that Firefox was not performing a check on paste
received from cross-processes. An attacker could potentially exploit this
to obtain sensitive information. (CVE-2022-46872)
