FileZilla Client version 184.108.40.206 fixes a minor security issue:
Quoting upstream news page:
FileZilla 220.127.116.11 fixes a vulnerability regarding the way some errors are
handled on SSL/TLS secured data transfers.
If the data connection of a transfer gets closed, FileZilla did not check if the
server performed an orderly TLS shutdown.
An attacker could send spoofed FIN packets to the client. Even though GnuTLS
detects this with GNUTLS_E_UNEXPECTED_PACKET_LENGTH, FileZilla did not record a
transfer failure in all cases.
Unfortunately not all servers perform an orderly SSL/TLS shutdown. Since this
cannot be distinguished from an attack, FileZilla will not be able to download
listings or files from such servers.
All versions prior to 18.104.22.168 are affected. This vulnerability has been fixed in
