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'

Risk factor :

High / CVSS Base Score : 7.8
