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" References ========== [ 1 ] gFTP Announcement http://archives.seul.org/gftp/announce/Feb-2005/msg00000.html [ 2 ] CAN-2005-0372 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0372 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200502-27.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
