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.

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.

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.

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 default configuration of Lotus Domino server 5.0.8 includes system information (version, operating system, and build date) in the HTTP headers of replies, which allows remote attackers to obtain sensitive information.

Buffer overflows 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 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.

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.

Buffer overflow in Lotus Notes LDAP (NLDAP) allows an attacker to conduct a denial of service through the ldap_search request.
