Details

It was 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 19.10

• spamassassin - 3.4.2-1ubuntu0.19.10.2

Ubuntu 18.04

• spamassassin - 3.4.2-0ubuntu0.18.04.3

Ubuntu 16.04

• spamassassin - 3.4.2-0ubuntu0.16.04.3

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