Vulnerability from variot - Updated: 2026-04-10 23:43

slapd in OpenLDAP 1.x before 1.2.12, and 2.x before 2.0.8, allows remote attackers to cause a denial of service (crash) via an invalid Basic Encoding Rules (BER) length field. Multiple versions of OpenLDAP contain vulnerabilities that may allow denial-of-service attacks. These vulnerabilities were revealed using the PROTOS LDAPv3 test suite and are documented in CERT Advisory CA-2001-18. If your site uses this product, the CERT/CC encourages you to follow the advice provided below. Vulnerabilities exist in slapd in OpenLDAP 1.x versions prior to 1.2.12 and 2.x versions prior to 2.0.8
