The Apache Software Foundation Security Team discovered a programming error in the apr-util library function apr_uri_parse. When parsing IPv6 literal addresses, it is possible that a length is incorrectly calculated to be negative, and this value is passed to memcpy. This may result in an exploitable vulnerability on some platforms, including FreeBSD.
