Description OSIDB Bzimport 2026-04-28 15:01:29 UTC 
Memory safety bugs present in Firefox ESR 140.10.0, Thunderbird ESR 140.10.0, Firefox 150.0.0 and Thunderbird 150.0.0. 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 was fixed in Firefox 150.0.1 and Firefox ESR 140.10.1.
