CVE-ID : CVE-2020-16044
Package : firefox
Type : arbitrary code execution
Remote : Yes
Link : https://security.archlinux.org/AVG-1413
The package firefox before version 84.0.2-1 is vulnerable to arbitrary
code execution.
Upgrade to 84.0.2-1.
The problem has been fixed upstream in version 84.0.2.
None.
A security issue was found in Firefox before 84.0.2. 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. Mozilla presumes that with
enough effort it could have been exploited to run arbitrary code.
A remote attacker might be able to execute arbitrary code via a crafted
SCTP packet.
