Description

Memory safety bugs present in Firefox 120, Firefox ESR 115.5, and Thunderbird 115.5. 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 ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.

Vendor	Product	Versions
Mozilla	Firefox ESR	affected `unspecified - < 115.6`
Mozilla	Thunderbird	affected `unspecified - < 115.6`
Mozilla	Firefox	affected `unspecified - < 121`
