Detailsinfo

A vulnerability classified as critical was found in Apache Xerces-C++. Affected by this vulnerability is some unknown functionality of the component XML Parser. The manipulation with an unknown input leads to a input validation vulnerability. The CWE definition for the vulnerability is CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. As an impact it is known to affect availability. The summary by CVE is:

The XML parser in Xerces-C++ before 3.0.0 allows context-dependent attackers to cause a denial of service (stack consumption and crash) via an XML schema definition with a large maxOccurs value, which triggers excessive memory consumption during validation of an XML file.
