NVD Description

Note: Versions mentioned in the description apply only to the upstream firefox-x11 package and not the firefox-x11 package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

Memory safety bugs present in Firefox 117, Firefox ESR 115.2, and Thunderbird 115.2. 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 < 118, Firefox ESR < 115.3, and Thunderbird < 115.3.
