Descriptions
Stack-based buffer overflow in Apache Xerces-C++ before 3.1.4 allows context-dependent attackers to cause a denial of service via a deeply nested DTD.
Desbordamiento de buffer basado en pila en Apache Xerces-C++ en versiones anteriores a 3.1.4 permite a atacantes dependientes del contexto provocar una denegación de servicio a través de un DTD anidado profundamente.
A stack exhaustion flaw was found in the way Xerces-C XML parser handled deeply nested DTDs. An attacker could potentially use this flaw to crash an application using Xerces-C by tricking it into processing specially crafted data.
Xerces-C is a validating XML parser written in a portable subset of C++. Xerces-C makes it easy to give your application the ability to read and write XML data. A shared library is provided for parsing, generating, manipulating, and validating XML documents. Issues addressed include a stack overflow vulnerability.
