Описание
When processing a MAR update file, after the signature has been validated, an invalid name length could result in a heap overflow, leading to memory corruption and potentially arbitrary code execution. Within Firefox as released by Mozilla, this issue is only exploitable with the Mozilla-controlled signing key. This vulnerability affects Firefox < 80.
Отчет
Firefox and thunderbird packages shipped with Red Hat Enterprise Linux do not enable automatic updates. Therefore are not affected by this flaw.
