Security Bulletin: TADDM 126.96.36.199: Apache Xerces-J XML parser Denial of Service attack.
The Apache Xerces-J XML parser is vulnerable to a denial of service attack, triggered by malformed XML data, that can affect the security of IBM Tivoli Application Dependency Discovery Manager.
CVEID: CVE-2013-4002 (CVSS 7.1)
The Apache Xerces-J XML parser is vulnerable to a denial of service attack, triggered by malformed XML data. The malformed data causes the XML parser to consume CPU resource for several minutes before the data is eventually rejected. This behavior can be used to launch a denial of service attack against any Java server application which processes XML data supplied by remote users. The same technique can be used to consume CPU resources on client deployments of Java.
The IBM Java SDK ships a variant of the Apache Xerces-J XML parser (XML4J) which has the same vulnerability. The vulnerability applies to all versions of the IBM Java SDK.
