+ <background>
+ <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>
