Severity: Normal
Title: gFTP: Directory traversal vulnerability
Date: February 19, 2005
Bugs: #81994
ID: 200502-27

---

Synopsis

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

Background

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

Affected packages

-------------------------------------------------------------------
 Package       /   Vulnerable   /                       Unaffected
-------------------------------------------------------------------

1 net-ftp/gftp < 2.0.18-r1 >= 2.0.18-r1

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"
