Description:
Some vulnerabilities have been discovered in IBM Lotus Domino Web Access, which can be exploited by malicious people to compromise a user's system.
1) Boundary errors in the Domino Web Access ActiveX control (inotes6.dll, inotes6w.dll, dwa7.dll, dwa7W.dll) can be exploited to cause stack-based buffer overflows by assigning an overly long string to the "General_ServerName" or "General_JunctionName" property and then calling the "InstallBrowserHelperDll()" method.
2) A boundary error in the Domino Web Access ActiveX control can be exploited to cause a stack-based buffer overflow by assigning an overly-long string to the "Mail_MailDbPath" property and then calling the "Mail_SetDefaultMailClient()" method.
3) The Domino Web Access ActiveX control includes the insecure "InstallBrowserHelperDll()" method, which can be exploited to e.g. download and register a malicious ActiveX control on a vulnerable system.
Successful exploitation of the vulnerabilities allow execution of arbitrary code.
The vulnerability is reported in dwa7W.dll version 7.0.34.1, confirmed in dwa7W.dll version 7.0.34.0, and reportedly affects IBM Lotus Domino 6.x (inotes6.dll, inotes6w.dll) and 7.x (dwa7.dll, dwa7W.dll). Other versions may also be affected.
Solution:
The "Mail_MailDbPath" property vulnerability is reportedly fixed in Lotus Domino Web Access version 6.5.6, 7.0.3, and 8.0.

The "General_ServerName" property vulnerability will reportedly be fixed in Lotus Domino Web Access version 8.0.1, and is targeted for version 7.0.4.
Set the kill-bit for the affected ActiveX controls.
