Description Doran Moppert 2020-09-03 06:07:50 UTC

Mozilla developers and community members reported memory safety bugs present in Thunderbird 77. 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.
