Sun Java System Directory Server 6.3.1

Directory Proxy Server (DPS) in Sun Java System Directory Server Enterprise Edition 6.0 through 6.3.1 does not enable the SO_KEEPALIVE 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 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.

Multiple unspecified vulnerabilities in (1) ns-slapd and (2) slapd.exe in Sun Directory Server Enterprise Edition 7.0, Sun Java System Directory Server 5.2, and Sun Java System Directory Server Enterprise Edition 6.0 through 6.3.1 allow remote attackers to cause a denial of service (daemon crash) via a crafted LDAP search request.

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.
