apr-util: Apache Portable Runtime Utility: Denial of Service via XML stack recursion attack

A flaw was found in Apache Portable Runtime Utility apr-util. A remote attacker could exploit a stack recursion vulnerability by providing specially crafted XML input to a library consumer that uses the aprxmlquoteelem function. This could lead to a denial of service DoS due to an application cra...
