- --------------------------BEGIN INCLUDED TEXT--------------------

Apache SpamAssassin 3.4.4 was recently released [1], and fixes an issue
of security note where nefarious rule configuration (.cf) files can be
configured to run system commands similar to CVE-2018-11805.

This issue is less stealthy and attempts to exploit the issue will throw 
warnings.

Thanks to Damian Lukowski at credativ for reporting the issue ethically.

With this bug unpatched, exploits can be injected in a number of scenarios
though doing so remotely is difficult.

In addition to upgrading to SA 3.4.4, we again recommend that users should
only use update channels or 3rd party .cf files from trusted places.

This issue has been assigned CVE id CVE-2020-1931 [2]

To contact the Apache SpamAssassin security team, please e-mail
