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.

The remote console in the Server Controller in IBM Lotus Domino 7.x and 8.x verifies credentials against a file located at a UNC share pathname specified by the client, which allows remote attackers to bypass authentication, and consequently execute arbitrary code, by placing this pathname in the COOKIEFILE field. NOTE: this might overlap CVE-2011-0920.

Unspecified vulnerability in the authentication functionality in the server in IBM Lotus Domino 8.x before 8.5.2 FP4 allows remote attackers to cause a denial of service (daemon crash) via a crafted Notes RPC packet.
