gFTP is vulnerable to directory traversal attacks, possibly leading to the creation or overwriting of arbitrary files.

2.  Impact Information


gFTP is a GNOME based, multi-threaded file transfer client.


gFTP lacks input validation of filenames received by remote servers.


An attacker could entice a user to connect to a malicious FTP server and conduct a directory traversal attack by making use of specially crafted filenames. This could lead to arbitrary files being created or overwritten.

3.  Resolution Information


There is no known workaround at this time.


All gFTP users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-ftp/gftp-2.0.18-r1"
