+ <background>
+ <p>
+ tnftp is a NetBSD FTP client with several advanced features.
+ </p>
+ </background>
+ <description>
+ <p>
+ The 'mget' function in cmds.c lacks validation of the filenames
+ that are supplied by the server.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>
+ An attacker running an FTP server could supply clients with
+ malicious filenames, potentially allowing the overwriting of arbitrary
+ files with the permission of the connected user.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All tnftp users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=net-ftp/tnftp-20050103"</code>
