<p>
Xerces-C++ is a validating XML parser written in a portable subset of
C++.
</p>
</background>
<description>
<p>
Frank Rast reported that the XML parser in Xerces-C++ does not
correctly handle an XML schema definition with a large maxOccurs value,
which triggers excessive memory consumption during the validation of an
XML file.
</p>
</description>
<impact type="normal">
<p>
A remote attacker could entice a user or automated system to validate
an XML file using a specially crafted XML schema file, leading to a
Denial of Service (stack consumption and crash).
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Xerces-C++ users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=dev-libs/xerces-c-3.0.0-r1"</code>
</resolution>
