IBM Lotus Notes before 6.5.6, and 7.x before 7.0.3; and Domino before 6.5.5 FP3, and 7.x before 7.0.2 FP1; uses weak permissions (Everyone:Full Control) for memory mapped files (shared memory) in IPC, which allows local users to obtain sensitive information, or inject Lotus Script or other character sequences into a session.

Multiple buffer overflows in tunekrnl in IBM Lotus Domino 6.x before 6.5.5 FP2 and 7.x before 7.0.2 allow local users to gain privileges and execute arbitrary code via unspecified vectors.

Format string vulnerability in Lotus Domino 6.0.x before 6.0.5 and 6.5.x before 6.5.4 allows remote attackers to cause a denial of service via the Notes protocol (NRPC).

NOTE: this issue has been disputed by the vendor. Cross-site scripting (XSS) vulnerability in IBM Lotus Notes R6 and Domino R6, and possibly earlier versions, allows remote attackers to execute arbitrary web script or HTML via square brackets at the beginning and end of (1) computed for display, (2) computed when composed, or (3) computed text element fields. NOTE: the vendor has disputed this issue, saying that it is not a problem with Notes/Domino itself, but with the applications that do not properly handle this feature
