#CVE-2022-40962: Memory safety bugs fixed in Thunderbird 102.3

ReporterMozilla developers and communityImpacthigh

Description

Mozilla developers Nika Layzell, Timothy Nikkel, Jeff Muizelaar, Sebastian Hengst, Andreas Pehrson, and the Mozilla Fuzzing Team reported memory safety bugs present in Thunderbird 102.2. 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.
