The Apache SpamAssassin project reports :

Apache SpamAssassin 3.4.5 was recently released [1], and fixes an issue of security note where malicious rule configuration (.cf) files can be configured to run system commands.

In Apache SpamAssassin before 3.4.5, exploits can be injected in a number of scenarios. In addition to upgrading to SA 3.4.5, users should only use update channels or 3rd party .cf files from trusted places.

Damian Lukowski discovered a flaw in spamassassin, a Perl-based spam filter using text analysis. Malicious rule configuration files, possibly downloaded from an updates server, could execute arbitrary commands under multiple scenarios.

The remote AlmaLinux 8 host has a package installed that is affected by a vulnerability as referenced in the ALSA-2021:4315 advisory.

  - In Apache SpamAssassin before 3.4.5, malicious rule configuration (.cf) files can be configured to run     system commands without any output or errors. With this, exploits can be injected in a number of     scenarios. In addition to upgrading to SA version 3.4.5, users should only use update channels or 3rd     party .cf files from trusted places. (CVE-2020-1946)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
