The Notes Remote Procedure Call (NRPC) protocol in IBM Lotus Notes Domino before 6.5.5 FP2 and 7.x before 7.0.2 does not require authentication to perform user lookups, which allows remote attackers to obtain the user ID file.

Buffer overflow in IBM Lotus Notes 6.5.x before 6.5.3 and 6.0.x before 6.0.5 allows remote attackers to cause a denial of service (crash) via unknown vectors related to Java applets, as identified by KSPR62F4KN.

Multiple stack-based buffer overflows in Autonomy (formerly Verity) KeyView SDK before 9.2.0, as used in Lotus Notes 6.5.4 and 7.0, allow remote attackers to execute arbitrary code via (1) a UUE file containing an encoded file with a long filename handled by uudrdr.dll, (2) a compressed ZIP file with a long filename handled by kvarcve.dll, (3) a TAR archive with a long filename that is extracted to a directory with a long path handled by the TAR reader (tarrdr.dll), (4) an email that contains a long HTTP, FTP, or // link handled by the HTML speed reader (htmsr.dll) or (5) an email containing a crafted long link handled by the HTML speed reader (htmsr.dll).

Directory traversal vulnerability in kvarcve.dll in Autonomy (formerly Verity) KeyView SDK before 9.2.0, as used in Lotus Notes 6.5.4 and 7.0, allows remote attackers to delete arbitrary files via a (1) ZIP, (2) UUE or (3) TAR archive that contains a .. (dot dot) in the filename, which is not properly handled when generating a preview.
