    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"
