        A security vulnerability has been identifed in IBM Lotus Notes file
        viewers versions 5.0, 6.5.6, 7.0, 8.0, 8.0.1, 8.0.2, 8.5, 8.5.1 [1]


        The vendor has provided the following information regarding this 
        "To exploit these vulnerabilities, an attacker would have to send a
        specially crafted file attachment to users, and then users would
        have to double-click the attachment and select "View".
        The specific issues vary depending on attachment type; however, they
        are all related in how the buffer overflow denial-of-service could be
        accomplished. In all cases, the issues involve viewing a malicious
        attachment from a Notes client on a Windows-based machine. Domino
        servers are not impacted." [1]


        IBM has released the following fix packs to correct the problem:
         * 8.0.2 Fix Pack 6 (Available on Fix Central as of July 26, 2010; release notice)
         * 8.5.1 Fix Pack 4 (Available on Fix Central by August 4, 2010; preliminary release notice)
        There are also various workarounds listed on their website. Versions
        5, 6, and 7 only have workarounds available. [1]
