IBM : Security Vulnerabilities, CVEs, Published In March 2001 (Denial of service)

Kernel leak in AfpaCache module of the Fast Response Cache Accelerator (FRCA) component of IBM HTTP Server 1.3.x and Websphere 3.52 allows remote attackers to cause a denial of service via a series of malformed HTTP requests that generate a "bad request" error.

Buffer overflow in Lotus Notes LDAP (NLDAP) allows an attacker to conduct a denial of service through the ldap_search request.
