spamassassin vulnerabilities


A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 19.10
  • Ubuntu 18.04 LTS
  • Ubuntu 16.04 LTS
Summary


Several security issues were fixed in SpamAssassin.

Software Description

  • spamassassin - Perl-based spam filter using text analysis
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 LTS
spamassassin - 3.4.2-0ubuntu0.18.04.3
Ubuntu 16.04 LTS
spamassassin - 3.4.2-0ubuntu0.16.04.3

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

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