Debian DLA-2062-1 : sa-exim security update

high Nessus Plugin ID 132759

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was found that sa-exim, the SpamAssassin filter for Exim, allows attackers to execute arbitrary code if users are allowed to run custom rules. A similar issue was fixed in spamassassin, CVE-2018-11805, which caused a functional regression in sa-exim. This update restores the compatibility between spamassassin and sa-exim. The security implications of sa-exim's greylisting function are also documented in /usr/share/doc/sa-exim/README.greylisting.gz.

For Debian 8 'Jessie', this problem has been fixed in version 4.2.1-14+deb8u1.

We recommend that you upgrade your sa-exim packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected sa-exim package.
