GLSA-200903-19 : Xerces-C++: Denial of Service

high Nessus Plugin ID 35817

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200903-19 (Xerces-C++: Denial of Service)

 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.
 Impact :

 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).
 Workaround :

 There is no known workaround at this time.

Solution

All Xerces-C++ users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/xerces-c-3.0.0-r1'
