IBM Tivoli Directory Server 5.2.0

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.

The get_filter_list function in IBM Tivoli Directory Server (TDS) 5.2 before 5.2.0.5-TIV-ITDS-LA0006 does not properly perform certain sub filter parsing, which allows remote authenticated users to cause a denial of service (infinite loop) via a malformed search filter.

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.

slapd daemon in IBM Tivoli Directory Server (ITDS) 5.2.0 and 6.0.0 binds using SASL EXTERNAL, which allows attackers to bypass authentication and modify and delete directory data via unknown attack vectors.

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.

IBM Tivoli Directory Server (TDS) 5.2 before 5.2.0.5-TIV-ITDS-LA0007 on AIX allows remote attackers to cause a denial of service (server destabilization) via an anonymous DIGEST-MD5 LDAP Bind operation.

Double free vulnerability in IBM Tivoli Directory Server (TDS) 5.2 before 5.2.0.5-TIV-ITDS-LA0005 allows remote authenticated users to cause a denial of service (ABEND) via search operations that trigger recursive filter_free calls.

Multiple memory leaks in the (1) ldap_init and (2) ldap_url_search_direct API functions in IBM Tivoli Directory Server (TDS) 5.2 before 5.2.0.5-TIV-ITDS-LA0007 allow remote authenticated users to cause a denial of service (memory consumption) by making many function calls.

IBM Tivoli Directory Server (TDS) 5.2 before 5.2.0.5-TIV-ITDS-LA0007 does not properly handle the simultaneous changing of multiple passwords, which makes it easier for remote authenticated users to cause a denial of service (DB2 daemon deadlock) by making password changes that trigger updates to a DB2 password-history table.

Memory leak in the ldap_explode_rdn API function in IBM Tivoli Directory Server (TDS) 5.2 before 5.2.0.5-TIV-ITDS-LA0007 allows remote authenticated users to cause a denial of service (memory consumption) by making many function calls.

IBM Tivoli Directory Server (TDS) 5.2 before 5.2.0.5-TIV-ITDS-IF0010 on Windows allows remote authenticated users to cause a denial of service (daemon hang) via a cn=changelog search.

The LDAP_ADD implementation in IBM Tivoli Directory Server (TDS) 5.2 before 5.2.0.5-TIV-ITDS-IF0009 stores a cleartext SHA password in the change log, which might allow local users to obtain sensitive information by reading this log.

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.
