Apache Portable Runtime Utility: apr-util XML stack recursion crash
A bug in APR-util version 1.6.3 (and earlier) allows a stack recursion attack against any library consumer which parses XML from untrusted sources and uses the aprxmlquote_elem() function.
Users are recommended to upgrade to version 1.6.4, which fixes this issue.
