2008-11-15 - FileZilla Client 3.1.5.1 released

Bugfixes and minor changes:

  • Connection establishment through SOCKS proxies could fail in some cases
  • Clearing private data no longer crashes if quickconnect bar is hidden
  • Handle drag & drop of symlinks
  • Update remote directory tree if deleting a subdirectory
  • Fix parsing of HTTP chunk lengths for the update downloader
  • Reduce memory consumption of remote directory tree
  • Rewrite the code that added local directories to the queue. New one is faster and avoids some potentially thread-unsafe behaviour of the old code
  • OS X: Fix help menu duplication on non-English systems
  • MSW: Reset wxWidgets internal display cache if changing display resolution or layout
  • MSW: Fixes for silent intaller

2008-11-03 - FileZilla Server 0.9.28 released

Bugfixes and minor changes:

  • Directly reject PROT C if PROT P is required instead of complaining after a transfer command

  • Server startup options in installer had no effect

2008-07-24 - Security Advisory

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
