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.

Notes

mdeslaur	starting with Ubuntu 22.04, the firefox package is just a script that installs the Firefox snap
