Description Tomas Hoger 2008-07-30 16:10:55 UTC 
FileZilla Client version 3.1.0.1 fixes a minor security issue:

Quoting upstream news page:

FileZilla 3.1.0.1 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.

Impact:
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.

Affected versions:
All versions prior to 3.1.0.1 are affected. This vulnerability has been fixed in
3.1.0.1
