Amazon Linux 2 : spamassassin (ALAS-2021-1642)

critical Nessus Plugin ID 149861

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of spamassassin installed on the remote host is prior to 3.4.4-3. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2021-1642 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.

Solution

Run 'yum update spamassassin' to update your system.
