Debian DSA-3057-1 : libxml2 - security update

medium Nessus Plugin ID 78694

Language:

Synopsis

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

Description

Sogeti found a denial of service flaw in libxml2, a library providing support to read, modify and write XML and HTML files. A remote attacker could provide a specially crafted XML file that, when processed by an application using libxml2, would lead to excessive CPU consumption (denial of service) based on excessive entity substitutions, even if entity substitution was disabled, which is the parser default behavior. (CVE-2014-3660 )

In addition, this update addresses a misapplied chunk for a patch released in version 2.8.0+dfsg1-7+wheezy1 (#762864), and a memory leak regression (#765770) introduced in version 2.8.0+dfsg1-7+nmu3.

Solution

Upgrade the libxml2 packages.

For the stable distribution (wheezy), this problem has been fixed in version 2.8.0+dfsg1-7+wheezy2.
