Title: libxml2: Denial of Service
Date: December 10, 2014
Bugs: #525656
ID: 201412-06
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
A vulnerability in libxml2 could result in Denial of Service.
Background
==========
libxml2 is the XML C parser and toolkit developed for the Gnome
project.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-libs/libxml2 < 2.9.2 >= 2.9.2
Description
===========
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.
Resolution
==========
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.
