Description Doran Moppert 2021-01-06 23:54:39 UTC
A malicious peer could have modified a COOKIE-ECHO chunk in a SCTP packet in a way that potentially resulted in a use-after-free. We presume that with enough effort it could have been exploited to run arbitrary code.

Comment 9 Doran Moppert 2021-01-11 23:20:58 UTC
Statement:

Regarding Thunderbird:  in general this flaw cannot be exploited through email in Thunderbird because scripting is disabled when reading mail, but it is potentially a risk in browser or browser-like contexts.
