installed on the remote host is earlier than Update 30 and is,
therefore, potentially affected by the following vulnerabilities:

  - A stack overflow error exists related to proxy
    tunnels. (Bug #6670868)

  - An error exists related to foreach loops containing
    generics that can lead to javac crashes. (Bug #6682380)

  - An error exists related to security exceptions in
    'AnnotationInvocationHandler.getMemberMethods'.
   (Bug #6761678)

  - An error in 'URI.equals' can allow a return value of
    'true' when handling escaped octets. (Bug #7041800)

  - An error related to 'liveconnect' can cause secure
    cookies not to be transferred. (Bug #7102914)

  - SSL connectivity is broken when using the cipher suite
    TLS_DH_anon_WITH_AES_128_CBC_SHA. (Bug #7103725)");
