Synopsis

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

Description

The remote Debian 12 host has a package installed that is affected by multiple vulnerabilities as referenced in the dsa-5555 advisory.

Two vulnerabilities were discovered in openvpn, a virtual private network application which could result in memory disclosure or denial of service. The oldstable distribution (bullseye) is not affected. For the stable distribution (bookworm), these problems have been fixed in version 2.6.3-1+deb12u2. We recommend that you upgrade your openvpn packages. For the detailed security status of openvpn please refer to its security tracker page at: https://security-tracker.debian.org/tracker/openvpn

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 openvpn packages.

For the stable distribution (bookworm), these problems have been fixed in version 2.6.3-1+deb12u2.
