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.
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.
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.
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.
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.
The do_extendedOp function in ibmslapd in IBM Tivoli Directory Server (TDS) 6.2 on Linux allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted SecureWay 3.2 Event Registration Request (aka a 1.3.18.0.2.12.1 request).
Heap-based buffer overflow in ibmdiradm in IBM Tivoli Directory Server (TDS) 6.0 on Linux allows remote attackers to have an unspecified impact via unknown vectors that trigger heap corruption, as demonstrated by a certain module in VulnDisco Pack Professional 8.11. NOTE: as of 20090903, this disclosure has no actionable information. However, because the VulnDisco Pack author is a reliable researcher, the issue is being assigned a CVE identifier for tracking purposes.
