Lotus Domino Servers 5.x, 4.6x, and 4.5x allows attackers to bypass the intended Reader and Author access list for a document's object via a Notes API call (NSFDbReadObject) that directly accesses the object.

Buffer overflow in bindsock in Lotus Domino 5.0.4 and 5.0.7 on Linux allows local users to gain root privileges via a long (1) Notes_ExecDirectory or (2) PATH environment variable.

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

Multiple unspecified vulnerabilities in IBM Lotus Notes and Domino Server before 6.5.5 allow attackers to cause a denial of service (application crash) via multiple vectors, involving (1) a malformed message sent to an "Out Of Office" agent (SPR LPEE6DMQWJ), (2) the compact command (RTIN5U2SAJ), (3) malformed bitmap images (MYAA6FH5HW), (4) the "Delete Attachment" action (YPHG6844LD), (5) parsing certificates from a remote Certificate Table (AELE6DZFJW), and (6) creating a SSL key ring with the Domino Administration client (NSUA4FQPTN).

Lotus Domino server 5.0.9a and earlier allows remote attackers to bypass security restrictions and view Notes database files and possibly sensitive Notes template files (.ntf) via an HTTP request with a large number of "+" characters before the .nsf file extension, which are converted to spaces by Domino.

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.

Lotus Domino R5 before R5.0.7a allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via miscellaneous packets with semi-valid BER encodings, as demonstrated by the PROTOS LDAPv3 test suite.

IBM Lotus Domino Server 7.0 allows remote attackers to cause a denial of service (segmentation fault) via a crafted packet to the LDAP port (389/TCP).

Format string vulnerabilities in Lotus Domino R5 before R5.0.7a allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code, as demonstrated by the PROTOS LDAPv3 test suite.

Lotus Notes Domino 6.0.2 on Linux installs the notes.ini configuration file with world-writable permissions, which allows local users to modify the Notes configuration and gain privileges.

Web Access in Lotus Domino 6.5.1 allows remote attackers to cause a denial of service (server crash) via a large e-mail message, as demonstrated using a large image attachment.

Lotus Notes R5 client R5.0.5 and earlier does not properly warn users when an S/MIME email message has been modified, which could allow an attacker to modify the email in transit without being detected.

Lotus Domino Web Server (nhttp.exe) before 6.0.1 allows remote attackers to cause a denial of service via an incomplete POST request, as demonstrated using the h_PageUI form.

Buffer overflow in the COM Object Control Handler for Lotus Domino 6.0.1 and earlier allows remote attackers to execute arbitrary code via multiple attack vectors, as demonstrated using the InitializeUsingNotesUserName method in the iNotes ActiveX control.

Multiple buffer overflows in Lotus Domino Web Server before 6.0.1 allow remote attackers to cause a denial of service or execute arbitrary code via (1) the s_ViewName option in the PresetFields parameter for iNotes, (2) the Foldername option in the PresetFields parameter for iNotes, or (3) a long Host header, which is inserted into a long Location header and used during a redirect operation.

The Lotus Notes 4.5 client may send a copy of encrypted mail in the clear across the network if the user does not set the "Encrypt Saved Mail" preference.

Lotus cc:Mail release 8 stores the postoffice password in plaintext in a hidden file which has insecure permissions, which allows local users to gain privileges.

Lotus Domino server 5.0.9a and earlier allows remote attackers to cause a denial of service by exhausting the number of working threads via a large number of HTTP requests for (1) an MS-DOS device name and (2) an MS-DOS device name with a large number of characters appended to the device name.

Buffer overflow in Lotus Domino web server before R5.0.10, when logging to DOMLOG.NSF, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long HTTP Authenticate header containing certain non-ASCII characters.

Lotus Domino 6.5.0 and 6.5.1, with IMAP enabled, allows remote authenticated users to change their quota by using the IMAP setquota command.
