Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 11 / 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5512 advisory.

Several vulnerabilities were discovered in Exim, a mail transport agent, which could result in remote code execution if the EXTERNAL or SPA/NTLM authenticators are used. For the oldstable distribution (bullseye), these problems have been fixed in version 4.94.2-7+deb11u1. For the stable distribution (bookworm), these problems have been fixed in version 4.96-15+deb12u2. We recommend that you upgrade your exim4 packages.
For the detailed security status of exim4 please refer to its security tracker page at: https://security- tracker.debian.org/tracker/exim4

Tenable has extracted the preceding description block directly from the Debian security advisory.

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

Solution

Upgrade the exim4 packages.

For the stable distribution (bookworm), these problems have been fixed in version 4.96-15+deb12u2.
