Debian DLA-151-1 : libxml2 security update

medium Nessus Plugin ID 82134

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that the update released for libxml2 in DSA 2978 fixing CVE-2014-0191 was incomplete. This caused libxml2 to still fetch external entities regardless of whether entity substitution or validation is enabled.

In addition, this update addresses a regression introduced in DSA 3057 by the patch fixing CVE-2014-3660. This caused libxml2 to not parse an entity when it's used first in another entity referenced from an attribute value.

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.
