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....
