FreeBSD : spamassassin -- Nefarious rule configuration files can run system commands (c86bfee3-4441-11ea-8be3-54e1ad3d6335)

high Nessus Plugin ID 133435

Language:

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

The Apache SpamAssassin project reports :

A nefarious rule configuration (.cf) files can be configured to run system commands. 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.

Solution

Update the affected package.
