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.
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.
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 6.0.0.59 (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.
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.
The doextendedOp 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 6.0.0.62 (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.
Memory leak in the ldapexplodedn 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.
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 slapiprintmessage 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.
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.
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.
