Описание
A flaw in Thunderbird's implementation of iCal causes a stack buffer overflow in icalrecur_add_bydayrules when processing certain email messages, resulting in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.7.1.
Меры по смягчению последствий
Thunderbird can be configured to use icaljs instead of libical by setting calendar.icaljs = true in preferences, mitigating this vulnerability.
