2021-06-24 CVE-2021-29947 Mozilla developers and community members reported memory safety bugs present in Firefox 87. 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 < 88.

Other operating systems are unaffected.*. This vulnerability... Firefox, Firefox_esr, Thunderbird 6.5
2021-06-24 CVE-2021-29952 When Web Render components were destructed, a race condition could have caused undefined behavior, and we presume that with enough effort may have been exploitable to run arbitrary code.
