  - Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 21

    than CVE-2013-2452 and CVE-2013-2455. NOTE: the previous information is from the June 2013 CPU. Oracle has
    not commented on claims from another vendor that this issue is due to an incorrect checking order within
    the AccessControlContext class. (CVE-2013-2443)

Note that Nessus relies on the presence of the package as reported by the vendor.");
