Modified files:
lib/libalias alias_db.c alias_ftp.c alias_local.h
Log:
- Added support for passive mode FTP by aliasing 227 replies.
It does mean that it is now possible to run passive-mode FTP
server behind NAT.
- SECURITY: FTP aliasing engine now ensures that:
o the segment preceding a PORT/227 segment terminates with a \r\n;
o the IP address in the PORT/227 matches the source IP address of
the packet;
o the port number in the PORT command or 277 reply is greater than
or equal to 1024.
