Integer signedness error in ndiiop.exe in the DIIOP implementation in the server in IBM Lotus Domino before 8.5.3 allows remote attackers to execute arbitrary code via a GIOP client request, leading to a heap-based buffer overflow.

Stack-based buffer overflow in nrouter.exe in IBM Lotus Domino before 8.5.3 allows remote attackers to execute arbitrary code via a long name parameter in a Content-Type header in a malformed Notes calendar (aka iCalendar or iCal) meeting request, aka SPR KLYH87LL23.

Stack-based buffer overflow in ndiiop.exe in the DIIOP implementation in the server in IBM Lotus Domino before 8.5.3 allows remote attackers to execute arbitrary code via a GIOP getEnvironmentString request, related to the local variable cache.

Multiple stack-based buffer overflows in the IBM Lotus Domino Web Access ActiveX control, as provided by inotes6.dll, inotes6w.dll, dwa7.dll, and dwa7w.dll, in Domino 6.x and 7.x allow remote attackers to execute arbitrary code, as demonstrated by an overflow from a long General_ServerName property value when calling the InstallBrowserHelperDll function in the Upload Module in the dwa7.dwa7.1 control in dwa7w.dll 7.0.34.1.

The LDAP server (nldap.exe) in IBM Lotus Domino before 7.0.1, 6.5.5, and 6.5.4 FP2 allows remote attackers to cause a denial of service (crash) via a long bind request, which triggers a null dereference.
