A stack buffer overflow flaw was found in the way 389-ds-base 1.3.6.x before 1.3.6.13, 1.3.7.x before 1.3.7.9, 1.4.x before 1.4.0.5 handled certain LDAP search filters. A remote, unauthenticated attacker could potentially use this flaw to make ns-slapd crash via a specially crafted LDAP request, thus resulting in denial of service.
389-ds-base version before 1.3.5.19 and 1.3.6.7 are vulnerable to password brute-force attacks during account lockout due to different return codes returned on password attempts.
389 Directory Server in Red Hat Enterprise Linux Desktop 6 through 7, Red Hat Enterprise Linux HPC Node 6 through 7, Red Hat Enterprise Linux Server 6 through 7, and Red Hat Enterprise Linux Workstation 6 through 7 allows remote attackers to infer the existence of RDN component objects.
