Xerces-C++ is a validating XML parser written in a portable subset of
|
|
C++.

<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 ">=dev-libs/xerces-c-3.0.0-r1"</code>
