                  Summary

                  A procedure is available to eliminate a security vulnerability affecting several web server
                  products. The vulnerability could potentially allow a malicious web site visitor to perform actions
                  that the system permissions authorize him to perform, but which he previously may have had
                  no means of actually carrying out. This is not a problem with ColdFusion Server itself, but it is
                  an issue that can affect ColdFusion users. Allaire recommends that customers follow the
                  instructions posted on the Microsoft Web site to address this issue. 

                  Issue

                  This issue is clearly explained in the Microsoft Security Bulletin: "The FrontPage 97 and 98
                  Server Extensions include two components, Htimage.exe and Imagemap.exe, that provide
                  CERN- and NCSA-compliant server side image mapping support, respectively, for legacy
                  browsers. Both components contain unchecked buffers that could be used to run arbitrary
                  code. Although part of the Server Extensions, these components also install as part of several
                  other web server products."

                  Further: "The risk posed by this vulnerability is significantly restricted by the fact that the
                  affected components run "out of process" and in the security context of the user. Thus, there is
                  no capability through this vulnerability to cause either the web service or the server itself to
                  crash, nor is there an opportunity to run code in an elevated security context. However, it still
                  could be possible for a malicious user to perform actions that, though permitted, he would
                  otherwise be unable to take because the functionality was not exposed via a web page or
                  script."

                  Affected Software Versions

                       FrontPage 97 Server Extensions, which ship as part of FrontPage 97 
                       FrontPage 98 Server Extensions, which ship as part of FrontPage 98 
                       Microsoft(r) Windows NT(r) 4.0 Option Pack, which is the primary distribution
                       mechanism for Internet Information Server 4.0 
                       Personal Web Server 4.0, which ships as part of Windows(r) 95 and 98
