"The version of Oracle (formerly Sun) Java Runtime Environment (JRE) 6.x
installed on the remote host is earlier than Update 43.  It, therefore,
potentially can allow remote code execution due to the following
vulnerabilities related to the '2D' sub-component :

  - An integer overflow error exists related to handling
    sample model instances that could result in memory
    corruption leading to arbitrary code execution.
    (CVE-2013-0809)

  - An unspecified error exists that could allow memory to
    be overwritten and could allow the security manager to
    be bypassed, thus leading to application crashes or
    arbitrary code execution. (CVE-2013-1493)

Please note this issue affects client deployments only and is exploited
through untrusted 'Java Web Start' applications and untrusted Java
applets.");
