gFTP: Directory traversal vulnerability — GLSA 200502-27

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

Affected packages

Package 	net-ftp/gftp on all architectures
Affected versions 	< 2.0.18-r1
Unaffected versions 	>= 2.0.18-r1

Background

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

Description

gFTP lacks input validation of filenames received by remote servers.

Impact

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.

Workaround

There is no known workaround at this time.

Resolution

All gFTP users should upgrade to the latest version:

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