OVERVIEW

        A number of vulnerabilities have been identified in IBM Lotus Notes.


IMPACT

        The vendor has provided the following details regarding these
        vulnerabilities:
        
        "In specific situations, arbitrary code could potentially be executed 
        when the following types of attachments are viewed in Notes:
        
            LZH archive
            RTF document
            Applix Spreadsheets
            Microsoft Excel document
            Microsoft Office document
            Lotus Notes .prz file
            Lotus Notes .zip file 
        
        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]


MITIGATION

        The vendor recommends applying the relevant fix packs to correct these 
        issues. [1]
