Debian DSA-3593-1 : libxml2 - security update

high Nessus Plugin ID 91447

Language:

Synopsis

The remote Debian host is missing a security-related 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.

Solution

Upgrade the libxml2 packages.

For the stable distribution (jessie), these problems have been fixed in version 2.9.1+dfsg1-5+deb8u2.
