SUN » Java System Directory Server : Security Vulnerabilities, CVEs, (Denial of service)

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.

The core_get_proxyauth_dn 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.

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.

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.

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.

Sun Java System Directory Proxy Server in Sun Java System Directory Server Enterprise Edition 6.0 through 6.3, when a JDBC data source is used, does not properly handle (1) a long value in an ADD or (2) long string attributes, which allows remote attackers to cause a denial of service (JDBC backend outage) via crafted LDAP requests.

Unspecified vulnerability in Sun Java System Directory Server 5.2 p6 and earlier, and Enterprise Edition 5, allows remote attackers to cause a denial of service (daemon crash) via crafted LDAP requests.

Unspecified vulnerability in the LDAP Software Development Kit (SDK) for C, as used in Sun Java System Directory Server 5.2 up to Patch 4 and Sun ONE Directory Server 5.1, allows remote attackers to cause a denial of service (crash) via certain BER encodings.

The LDAP server (ns-slapd) in Sun Java System Directory Server 5.2 Patch4 and earlier and ONE Directory Server 5.1 and 5.2 allows remote attackers to cause a denial of service (crash) via malformed queries, probably malformed BER queries, which trigger a free of uninitialized memory locations.

Memory leak in Network Security Services (NSS) 3.11, as used in Sun Java Enterprise System 2003Q4 through 2005Q1 and Java System Directory Server 5.2, allows remote attackers to cause a denial of service (memory consumption) by performing a large number of RSA cryptographic operations.

LDAP service in Sun Java System Directory Server 5.2, running on Linux and possibly other platforms, allows remote attackers to cause a denial of service (memory allocation error) via an LDAP packet with a crafted subtree search request, as demonstrated using the ProtoVer LDAP test suite.

Stack-based buffer overflow in help.cgi in the HTTP administrative interface for (1) Sun Java System Directory Server 5.2 2003Q4, 2004Q2, and 2005Q1, (2) Red Hat Directory Server and (3) Certificate Server before 7.1 SP1, (4) Sun ONE Directory Server 5.1 SP4 and earlier, and (5) Sun ONE Administration Server 5.2 allows remote attackers to cause a denial of service (admin server crash), or local users to gain root privileges.
