CVE-ID : CVE-2020-16044
Package : thunderbird
Type : arbitrary code execution
Remote : Yes
Link : https://security.archlinux.org/AVG-1440
The package thunderbird before version 78.6.1-1 is vulnerable to
arbitrary code execution.
Upgrade to 78.6.1-1.
The problem has been fixed upstream in version 78.6.1.
None.
A security issue was found in Firefox before 84.0.2 and Thunderbird
before 78.6.1-1. A malicious peer could have modified a COOKIE-ECHO
chunk in an SCTP packet in a way that potentially resulted in a use-
after-free. Mozilla presumes that with enough effort it could have been
exploited to run arbitrary code.
A malicious remote user could forge an SCTP packet and possibly execute
arbitrary code.
