Memory safety bugs present in 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. This
vulnerability affects Thunderbird < 102.8 and Firefox ESR < 102.8.

Notes

Author	Note
tyhicks	mozjs contains a copy of the SpiderMonkey JavaScript engine
mdeslaur	starting with Ubuntu 22.04, the firefox package is just a script that installs the Firefox snap
