    scponly is a shell for restricting user access to file transfer only
    using sftp and scp.

    <p>
    Joachim Breitner reported that Subversion and rsync support invokes
    subcommands in an insecure manner (CVE-2007-6350). It has also been
    discovered that scponly does not filter the -o and -F options to the
    scp executable (CVE-2007-6415).
    </p>
  </description>
  <impact type="normal">
    <p>
    A local attacker could exploit these vulnerabilities to elevate
    privileges and execute arbitrary commands on the vulnerable host.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All scponly users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-misc/scponly-4.8&quot;</code>
    <p>
    Due to the design of scponly's Subversion support, security
    restrictions can still be circumvented. Please read carefully the
    SECURITY file included in the package.
    </p>
