Debian DLA-503-1 : libxml2 security update

high Nessus Plugin ID 91472

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Several vulnerabilities were discovered in libxml2, a library providing support to read, modify and write XML and HTML files. A remote attacker could provide a specially crafted XML or HTML file that, when processed by an application using libxml2, would cause a denial of service against the application, or potentially the execution of arbitrary code with the privileges of the user running the application.

For Debian 7 'Wheezy', these problems have been fixed in version 2.8.0+dfsg1-7+wheezy6.

We recommend that you upgrade your libxml2 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
