IBM Global Security Kit (aka GSKit) before 8.0.14.22, as used in IBM Rational Directory Server, IBM Tivoli Directory Server, and other products, uses the PKCS #12 file format for certificate objects without enforcing file integrity, which makes it easier for remote attackers to spoof SSL servers via vectors involving insertion of an arbitrary root Certification Authority (CA) certificate.

IBM Global Security Kit (aka GSKit) before 8.0.14.22, as used in IBM Rational Directory Server, IBM Tivoli Directory Server, and other products, does not properly validate data during execution of a protection mechanism against the Vaudenay SSL CBC timing attack, which allows remote attackers to cause a denial of service (application crash) via crafted values in the TLS Record Layer, a different vulnerability than CVE-2012-2333.

IBM Tivoli Directory Server (TDS) 6.3 and earlier allows remote attackers to cause a denial of service (daemon crash) via a malformed LDAP paged search request.

The default configuration of TLS in IBM Tivoli Directory Server (TDS) 6.3 and earlier supports the (1) NULL-MD5 and (2) NULL-SHA ciphers, which allows remote attackers to trigger unencrypted communication via the TLS Handshake Protocol.

IBM Tivoli Directory Server (TDS) 5.2 before 5.2.0.5-TIV-ITDS-IF0010, 6.0 before 6.0.0.67 (aka 6.0.0.8-TIV-ITDS-IF0009), 6.1 before 6.1.0.40 (aka 6.1.0.5-TIV-ITDS-IF0003), 6.2 before 6.2.0.16 (aka 6.2.0.3-TIV-ITDS-IF0002), and 6.3 before 6.3.0.3 (aka 6.3.0.0-TIV-ITDS-IF0003) does not properly handle the ibm-auditAttributesOnGroupEvalOp setting for auditing of extended operations, which might allow attackers to obtain sensitive information by reading the audit log.

Stack-based buffer overflow in the server process in ibmslapd.exe in IBM Tivoli Directory Server (TDS) 5.2 before 5.2.0.5-TIV-ITDS-IF0010, 6.0 before 6.0.0.67 (aka 6.0.0.8-TIV-ITDS-IF0009), 6.1 before 6.1.0.40 (aka 6.1.0.5-TIV-ITDS-IF0003), 6.2 before 6.2.0.16 (aka 6.2.0.3-TIV-ITDS-IF0002), and 6.3 before 6.3.0.3 (aka 6.3.0.0-TIV-ITDS-IF0003) allows remote attackers to execute arbitrary code via a crafted LDAP request. NOTE: some of these details are obtained from third party information.

Use-after-free vulnerability in the proxy-server implementation in IBM Tivoli Directory Server (TDS) 6.0 before 6.0.0.65 (aka 6.0.0.8-TIV-ITDS-IF0007) and 6.3 before 6.3.0.1 (aka 6.3.0.0-TIV-ITDS-IF0001) allows remote authenticated users to cause a denial of service (daemon crash) via a paged search that is interrupted by an LDAP Unbind operation.

IBM Tivoli Directory Server (TDS) 6.0 before 6.0.0.62 (aka 6.0.0.8-TIV-ITDS-IF0004) does not perform certain locking of linked-list access, which allows remote authenticated users to cause a denial of service (daemon crash) via a paged search.

IBM Tivoli Directory Server (TDS) 6.0 before 6.0.0.63 (aka 6.0.0.8-TIV-ITDS-IF0005) allows remote authenticated users to cause a denial of service (daemon hang) via a paged search that triggers improper mutex processing.

IBM Tivoli Directory Server (TDS) 6.0 before 6.0.0.63 (aka 6.0.0.8-TIV-ITDS-IF0005) allows remote authenticated users to cause a denial of service (daemon crash or hang) via a paged search, as demonstrated by a certain idsldapsearch command, related to an improper ibm-slapdIdleTimeOut configuration setting.

The do_extendedOp function in ibmslapd in IBM Tivoli Directory Server (TDS) 6.0 before 6.0.0.62 (aka 6.0.0.8-TIV-ITDS-IF0004) on Linux, Solaris, and Windows allows remote authenticated users to cause a denial of service (ABEND) via a malformed LDAP extended operation that triggers certain comparisons involving the NULL operation OID.

IBM Tivoli Directory Server (TDS) 6.0 before 6.0.0.59 (aka 6.0.0.8-TIV-ITDS-IF0001) allows remote authenticated users to cause a denial of service (infinite loop and daemon hang) by adding a nested group that contains the Distinguished Name (DN) of its parent entry.

Memory leak in the ldap_explode_dn function in IBM Tivoli Directory Server (TDS) 6.0 before 6.0.0.61 (aka 6.0.0.8-TIV-ITDS-IF0003) allows remote authenticated users to cause a denial of service (memory consumption) via an empty string argument.

Use-after-free vulnerability in the proxy server in IBM Tivoli Directory Server (TDS) 6.0.0.x before 6.0.0.8-TIV-ITDS-IF0007 and 6.1.x before 6.1.0-TIV-ITDS-FP0005 allows remote attackers to cause a denial of service (daemon crash) via an unbind request that occurs during a certain search operation.

IBM Tivoli Directory Server (TDS) 6.0.0.x before 6.0.0.8-TIV-ITDS-IF0007 does not properly handle invalid buffer references in LDAP BER requests, which might allow remote attackers to cause a denial of service (daemon crash) via vectors involving a buffer that has a memory address near the maximum possible address.

The slapi_printmessage function in IBM Tivoli Directory Server (ITDS) before 6.0.0.8-TIV-ITDS-IF0006 allows remote attackers to cause a denial of service (daemon crash) via multiple incomplete DIGEST-MD5 connection attempts.
