Resolution ========== Upgrade to 92.0-1. # pacman -Syu "firefox>=92.0-1" The problems have been fixed upstream in version 92.0. Workaround ========== None. Description =========== - CVE-2021-38491 (insufficient validation) In Firefox before version 92, mixed-content checks were unable to analyze opaque origins which led to some mixed content being loaded. - CVE-2021-38494 (arbitrary code execution) Mozilla developers reported memory safety bugs present in Firefox 91. Some of these bugs showed evidence of memory corruption and Mozilla presumes that with enough effort some of these could have been exploited to run arbitrary code.
