Gustavo Grieco discovered that xerces-c, a validating XML parser library for C++, mishandles certain kinds of malformed input documents, resulting in buffer overflows during processing and error reporting. These flaws could lead to a denial of service in applications using the xerces-c library, or potentially, to the execution of arbitrary code.
