Releases
Packages

Details
Damian Lukowski discovered that SpamAssassin incorrectly handled certain CF
files. If a user or automated system were tricked into using a specially-
crafted CF file, a remote attacker could possibly run arbitrary code.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 20.04
Ubuntu 18.04
Ubuntu 16.04
In general, a standard system update will make all the necessary changes.
