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.

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.

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.

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.

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.

The web administration tool in IBM Tivoli Security Directory Server 6.0 before iFix 75, 6.1 before iFix 68, 6.2 before iFix 44, and 6.3 before iFix 37 and IBM Security Directory Server 6.3.1 before iFix 11 and 6.4 before iFix 2 allows local users to gain privileges via vectors related to argument injection.
