Debian DLA-3012-1 : libxml2 - LTS security update

medium Nessus Plugin ID 161243

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 9 host has packages installed that are affected by a vulnerability as referenced in the dla-3012 advisory.

 Felix Wilhelm discovered that libxml2, the GNOME XML library, did not correctly check for integer overflows or used wrong types for buffer sizes. This could result in out-of-bounds writes or other memory errors when working on large, multi-gigabyte buffers. For Debian 9 stretch, this problem has been fixed in version 2.9.4+dfsg1-2.2+deb9u7. We recommend that you upgrade your libxml2 packages. For the detailed security status of libxml2 please refer to its security tracker page at: https://security- tracker.debian.org/tracker/libxml2 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 this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the libxml2 packages.

For Debian 9 stretch, this problem has been fixed in version 2.9.4+dfsg1-2.2+deb9u7.
