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

• spamassassin - 3.4.4-1ubuntu1.1

Ubuntu 18.04

• spamassassin - 3.4.2-0ubuntu0.18.04.5

Ubuntu 16.04

In general, a standard system update will make all the necessary changes.
