Synopsis

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

Description

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2700 advisory.

A buffer overflow was discovered in HTMLDOC, a HTML processor that generates indexed HTML, PS, and PDF, which could potentially result in the execution of arbitrary code. In addition a number of crashes were addressed. For Debian 9 stretch, these problems have been fixed in version 1.8.27-8+deb9u1. We recommend that you upgrade your htmldoc packages. For the detailed security status of htmldoc please refer to its security tracker page at: https://security-tracker.debian.org/tracker/htmldoc Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS

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 htmldoc packages.

For Debian 9 stretch, these problems have been fixed in version 1.8.27-8+deb9u1.
