critical Nessus Plugin ID 151219

Language:

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.

- HTMLDOC 1.9.7 allows a stack-based buffer overflow in the hd_strlcpy() function in string.c (when called from render_contents in ps-pdf.cxx) via a crafted HTML document. (CVE-2019-19630)

- Integer overflow in the htmldoc 1.9.11 and before may allow attackers to execute arbitrary code and cause a denial of service that is similar to CVE-2017-9181. (CVE-2021-20308)

Note that Nessus has not tested for this issue 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.
