GLSA-200502-27 : gFTP: Directory traversal vulnerability
Medium Nessus Plugin ID 17153
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200502-27 (gFTP: Directory traversal vulnerability)
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.
There is no known workaround at this time.
SolutionAll gFTP users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-ftp/gftp-2.0.18-r1'
