Summary
389-ds-base vulnerabilities
Details

It was discovered that 389 Directory Server presented to users, during authentication, an error message which could be used to discover if a certain LDAP DN existed or not. A remote unauthenticated attacker could possibly use this to check the existence of an entry in a LDAP database and expose sensitive information. This issue affected only Ubuntu 20.04 ESM. (CVE-2020-35518)

It was discovered that 389 Directory Server was incorrectly validating data used to access memory addresses. An authenticated attacker using a Syncrepl client could use this issue with a specially crafted query to cause 389 Directory Server to crash, resulting in a denial of service. (CVE-2021-3514)
