<title>libxml2: Denial of Service</title>
<synopsis>A vulnerability in libxml2 could result in Denial of Service.</synopsis>
<product type="ebuild">libxml2</product>
<announced>December 10, 2014</announced>
<revised>December 10, 2014: 1</revised>
<bug>525656</bug>
<access>local, remote</access>
<affected>
<package name="dev-libs/libxml2" auto="yes" arch="*">
<unaffected range="ge">2.9.2</unaffected>
<vulnerable range="lt">2.9.2</vulnerable>
</package>
</affected>
<background>
<p>libxml2 is the XML C parser and toolkit developed for the Gnome project.</p>
</background>
<description>
<p>parser.c in libxml2 before 2.9.2 does not properly prevent entity
expansion even when entity substitution has been disabled.
</p>
</description>
<impact type="normal">
<p>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.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All libxml2 users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/libxml2-2.9.2"
</code>
<p>Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying these packages.
</p>
