the xmlNanoFTPScanURL function, (2) a long proxy URL containing FTP
data that is not properly handled by the xmlNanoFTPScanProxy function,
and other overflows related to manipulation of DNS length values,
including (3) xmlNanoFTPConnect, (4) xmlNanoHTTPConnectHost, and (5)
xmlNanoHTTPConnectHost.";
