+Subject: ftp: validate PASV/LPSV response address against control connection
+ peer
+
+* src/ftp-basic.c (ftp_pasv): Reject if peer address doesn't match advertised
+  address,
+  (ftp_lpsv): Likewise.
+
+ftp_pasv() and ftp_lpsv() copied the IP address and port advertised in
+the server's 227 response without checking that it matched the peer
+of the control connection.  A malicious or compromised FTP server
+could therefore direct wget's data connection to an arbitrary host and
+port of its choosing (e.g. an internal service unreachable from the
+attacker directly), which is a server-side request forgery.
+
+ftp_epsv() was already safe since it only extracts a port and reuses
+the pre-filled control-connection address.
+
+Fix ftp_pasv() and ftp_lpsv() the same way: capture the control
+connection's peer address via socket_ip_address() before parsing the
+response, and reject the response (FTPINVPASV) if the parsed address
+does not match.
+
+Verified with a fake FTP server that returns a PASV response pointing
+at a different loopback address (127.0.0.2 instead of the real peer
+127.0.0.1): before the fix wget connects to the spoofed address, after
+the fix it rejects the response with "Cannot parse PASV response."
+Legitimate transfers using a correctly-addressed PASV response
+continue to work.
