GLSA-201412-06 : libxml2: Denial of Service

medium Nessus Plugin ID 79959

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-201412-06 (libxml2: Denial of Service)

parser.c in libxml2 before 2.9.2 does not properly prevent entity expansion even when entity substitution has been disabled.
Impact :

A context-dependent attacker could entice a user to a specially crafted XML file using an application linked against libxml2, possibly resulting in a Denial of Service condition.
Workaround :

There is no known workaround at this time.

Solution

All libxml2 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/libxml2-2.9.2' Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying these packages.
