A heap overflow flaw was found in 389-ds-base. This issue leads to a denial of service when writing a value larger than 256 chars in log_entry_attr.

An access control bypass vulnerability found in 389-ds-base. That mishandling of the filter that would yield incorrect results, but as that has progressed, can be determined that it actually is an access control bypass. This may allow any remote unauthenticated user to issue a filter that allows searching for database items they do not have access to, including but not limited to potentially userPassword hashes and other sensitive data.

When binding against a DN during authentication, the reply from 389-ds-base will be different whether the DN exists or not. This can be used by an unauthenticated attacker to check the existence of an entry in the LDAP database.

A flaw was found in the 389 Directory Server that allows users to cause a crash in the LDAP server using ldapsearch with server side sort.
