The coregetproxyauthdn function in ns-slapd in Sun Java System Directory Server Enterprise Edition 7.0 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted LDAP Search Request message.
Directory Proxy Server (DPS) in Sun Java System Directory Server Enterprise Edition 6.0 through 6.3.1 does not enable the SOKEEPALIVE socket option, which makes it easier for remote attackers to cause a denial of service (connection slot exhaustion) via multiple connections, aka Bug Id 6782659.
Directory Proxy Server (DPS) in Sun Java System Directory Server Enterprise Edition 6.0 through 6.3.1 does not properly handle multiple client connections within a short time window, which allows remote attackers to hijack the backend connection of an authenticated user, and obtain the privileges of this user, by making a client connection in opportunistic circumstances, related to "long binds," aka Bug Ids 6828462 and 6823593.
Directory Proxy Server (DPS) in Sun Java System Directory Server Enterprise Edition 6.0 through 6.3.1 does not properly implement the max-client-connections configuration setting, which allows remote attackers to cause a denial of service (connection slot exhaustion) by making multiple connections and performing no operations on these connections, aka Bug Id 6648665.
Unspecified vulnerability in the psearch (aka persistent search) functionality in Directory Proxy Server (DPS) in Sun Java System Directory Server Enterprise Edition 6.0 through 6.3.1 allows remote attackers to cause a denial of service (psearch outage) by using a crafted psearch client to send requests that trigger a psearch thread loop, aka Bug Id 6855978.
The Online Help feature in Sun Java System Directory Server 5.2 and Enterprise Edition 5 allows remote attackers to determine the existence of files and directories, and possibly obtain partial contents of files, via unspecified vectors.
Unspecified vulnerability in Sun ONE/Java System Directory Server (slapd) 6.0, and 5.x before 5.2 Patch 5, allows remote attackers to determine the existence of attributes of an entry via unspecified vectors.
Unknown vulnerability in ns-ldapd for Sun ONE Directory Server 4.16, 5.0, and 5.1 allows LDAP clients to cause a denial of service (service halt).
Directory traversal vulnerability in ViewLog for iPlanet Administration Server 5.1 (aka Sun ONE) allows remote attackers to read arbitrary files via "..%2f" (partially encoded dot dot) sequences.
