ns-slapd in 389 Directory Server before 1.3.0.8 allows remote attackers to cause a denial of service (server crash) via a crafted Distinguished Name (DN) in a MOD operation request.
389 Directory Server does not properly restrict access to entity attributes, which allows remote authenticated users to obtain sensitive information via a search query for the attribute.
