Title
Memory safety bugs fixed in Firefox ESR 115.29, Firefox ESR 140.4, Thunderbird ESR 140.4, Firefox 144 and Thunderbird 144
Summary
Memory safety bugs present in Firefox ESR 115.28, Firefox ESR 140.3, Thunderbird ESR 140.3, Firefox 143 and Thunderbird 143. 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 144, Firefox ESR 115.29, Firefox ESR 140.4, Thunderbird 144, and Thunderbird 140.4.
