  <title>Linux Terminal Server Project: Multiple vulnerabilities</title>
  <synopsis>
    Multiple vulnerabilities have been discovered in components shipped with
    LTSP which allow remote attackers to compromise terminal clients.

    The Linux Terminal Server Project adds thin-client support to Linux
    servers.

    LTSP version 4.2, ships prebuilt copies of programs such as the Linux
    Kernel, the X.org X11 server (GLSA 200705-06, GLSA 200710-16, GLSA
    200801-09), libpng (GLSA 200705-24, GLSA 200711-08), Freetype (GLSA
    200705-02, GLSA 200705-22) and OpenSSL (GLSA 200710-06, GLSA 200710-30)
    which were subject to multiple security vulnerabilities since 2006.
    Please note that the given list of vulnerabilities might not be
    exhaustive.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could possibly exploit vulnerabilities in the
    aforementioned programs and execute arbitrary code, disclose sensitive
    data or cause a Denial of Service within LTSP 4.2 clients.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    LTSP 4.2 is not maintained upstream in favor of version 5. Since
    version 5 is not yet available in Gentoo, the package has been masked.
    We recommend that users unmerge LTSP:
    </p>
    <code>
    # emerge --unmerge net-misc/ltsp</code>
    <p>
    If you have a requirement for Linux Terminal Servers, please either set
    up a terminal server by hand or use one of the distributions that
    already migrated to LTSP 5. If you want to contribute to the
    integration of LTSP 5 in Gentoo, or want to follow its development,
    find details in bug 177580.
    </p>
  </resolution>
