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.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
