Description David Kilzer 2016-04-21 01:58:03 UTC 
There are two more leaks in xmlNanoFTPConnect() after Bug 732352 was fixed:

<https://git.gnome.org/browse/libxml2/tree/nanoftp.c#n880>

	if (proxy) {
	    if (getaddrinfo (proxy, NULL, &hints, &result) != 0) {
		__xmlIOErr(XML_FROM_FTP, 0, "getaddrinfo failed");
		// Leak of result here if set.
		return (-1);
	    }
	}
	else
	    if (getaddrinfo (ctxt->hostname, NULL, &hints, &result) != 0) {
		__xmlIOErr(XML_FROM_FTP, 0, "getaddrinfo failed");
		// Leak of result here if set.
		return (-1);
	    }

If the result is non-zero, `getaddrinfo` failed and no `struct addrinfo` is
returned in `result`.
