Description Robert Frohl 2021-08-20 09:06:01 UTC
CVE-2021-29981

An issue present in lowering/register allocation could have led to obscure but
deterministic register confusion failures in JITted code that would lead to a
potentially exploitable crash. This vulnerability affects Firefox < 91 and
Thunderbird < 91.
