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

Lotus Domino 5.0.8 web server returns different error messages when a valid or invalid user is provided in HTTP requests, which allows remote attackers to determine valid user names and makes it easier to conduct brute force attacks.

IBM Lotus Domino Web Access (DWA) 7.0.1 does not expire a client's Lightweight Third-Party Authentication token (LtpaToken) upon logout, which allows remote attackers to obtain a user's privileges by intercepting the LtpaToken cookie.

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.

Multiple cross-site scripting (XSS) vulnerabilities in Lotus Domino iNotes Client 6.5.4 and 7.0 allow remote attackers to inject arbitrary web script or HTML via (1) an email subject; (2) an encoded javascript URI, as demonstrated using "java
script:"; or (3) when the Domino Web Access ActiveX control is not installed, via an email attachment filename.

Cross-site scripting (XSS) vulnerability in Lotus Domino iNotes Client 6.5.4 allows remote attackers to inject arbitrary web script or HTML via email with attached html files, which are directly rendered in the browser.

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.

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.

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.

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).

Multiple memory leaks in IBM Lotus Notes and Domino Server before 6.5.5 allow attackers to cause a denial of service (memory consumption and crash) via unknown vectors related to (1) unspecified vectors during the SSL handshake (SPR# MKIN67MQVW), (2) the stash file during the SSL handshake (SPR# MKIN693QUT), and possibly other vectors. NOTE: due to insufficient information in the original vendor advisory, it is not clear whether there is an attacker role in other memory leaks that are specified in the advisory.

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.

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).

Multiple unspecified vulnerabilities in IBM Lotus Notes and Domino Server before 6.5.5 have unknown impact and attack vectors, due to "potential security issues" as identified by SPR numbers (1) GPKS6C9J67 in Agents, (2) JGAN6B6TZ3 and (3) KSPR699NBP in the Router, (4) GPKS5YQGPT in Security, or (5) HSAO6BNL6Y in the Web Server. NOTE: vector 3 is related to an issue in NROUTER in IBM Lotus Notes and Domino Server before 6.5.4 FP1, 6.5.5, and 7.0, which allows remote attackers to cause a denial of service (CPU consumption) via a crafted vCal meeting request sent via SMTP (aka SPR# KSPR699NBP).

Lotus Domino Web Server (nhttp.exe) before 6.0.1 allows remote attackers to cause a denial of service via a "Fictionary Value Field POST request" as demonstrated using the s_Validation form with a long, unknown parameter name.

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.

Unspecified vulnerability in IBM Lotus Notes and Domino Server before 6.5.5, when running on AIX, allows attackers to cause a denial of service (deep recursion leading to stack overflow and crash) via long formulas.

Buffer overflow in IBM Lotus Notes and Domino Server before 6.5.5 allows attackers to cause a denial of service (router crash or hang) via unspecified vectors involving "CD to MIME Conversion".

Lotus Domino R5 and R6 WebMail, with "Generate HTML for all fields" enabled, stores sensitive data from names.nsf in hidden form fields, which allows remote attackers to read the HTML source to obtain sensitive information such as (1) the password hash in the HTTPPassword field, (2) the password change date in the HTTPPasswordChangeDate field, (3) the client platform in the ClntPltfrm field, (4) the client machine name in the ClntMachine field, and (5) the client Lotus Domino release in the ClntBld field, a different vulnerability than CVE-2005-2696.

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.
