"The remote host has a version of Oracle Secure Global Desktop that is
version 4.63, 4.71, 5.0 or 5.1. It is, therefore, affected by the
following vulnerabilities :

  - A buffer overflow flaw exists in the 'bdfReadCharacters'
    function within 'bitmap/bdfread.c' of the included X.Org
    libXfont. This could allow a remote attacker to cause a
    denial of service attack or possibly execute arbitrary
    code. (CVE-2013-6462)

  - A flaw exists with the Workspace Web Application. This
    could allow a remote attacker to impact the integrity of
    the application. Note this only affects versions
    5.0 and 5.1 of Oracle Secure Global Desktop.
    (CVE-2014-2439)

  - A flaw exists with the Workspace Web Application. This
    could allow a remote attacker to impact the
    confidentiality and integrity of the application.
    (CVE-2014-2463)

Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported patch information.");
