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.
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.
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 on AIX allows remote attackers to cause a denial of service (server destabilization) via an anonymous DIGEST-MD5 LDAP Bind operation.
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.
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.
