Multiple cross-site scripting (XSS) vulnerabilities in IBM Lotus Domino 7.x and 8.x before 8.5.4 allow remote attackers to inject arbitrary web script or HTML via (1) a URL accessed during use of the Mail template in the WebMail UI or (2) a URL accessed during use of Domino Help through the Domino HTTP server.

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.

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.

Cross-site scripting (XSS) vulnerability in help/readme.nsf/Header in the Help component in IBM Lotus Domino 7.x before 7.0.4 and 8.x before 8.0.2 allows remote attackers to inject arbitrary web script or HTML via the BaseTarget parameter in an OpenPage action. NOTE: this may overlap CVE-2010-0920.
