April 2015 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An attacker can force a read at an invalid address in
XMLReader.cpp of Apache Xerces-C++, in order to trigger a denial
of service.
Impacted products: Xerces-C++, Debian, Fedora
Severity: 2/4
Creation date: 20/03/2015
DESCRIPTION OF THE VULNERABILITY
The Apache Xerces-C++ product uses the src/xercesc/internal/XMLReader.cpp
file to analyze XML data.
However, several XMLReader.cpp finction try to read a memory area
which is not reachable, which triggers a fatal error.
An attacker can therefore force a read at an invalid address in
XMLReader.cpp of Apache Xerces-C++, in order to trigger a denial
of service.
