setup-ds.pl and setup-ds-admin.pl scripts used to configure Red Hat / 389 Directory Server instances and administration server instances creates a cache file containing configuration parameters provided by administrator configuring directory server. The file is created in /tmp with random name as setupXXXXXX.inf. It contains information such as directory server instance name, user and group under with ns-slapd should run, network port directory and administration server should listen on, base DN and administrative user names and accounts. This file is created with permissions depending on current umask setting, which is 022 for root account by default, which results in file being created as world readable. Any local user can take advantage of the weak file permissions and obtain administrative account passwords, which give them full control over directory server instance.

This file is removed at the end of the setup run which limits exposure, but it is not removed when setup is started with -k or --keepcache.

For additional details and patch changing setup scripts to always create cache file with restricted permissions, see: https://bugzilla.redhat.com/showbug.cgi?id=593392

389 Directory Server 1.2.11.15 (aka Red Hat Directory Server before 8.2.11-14) allows remote authenticated users to cause a denial of service (crash) via multiple @ characters in a GER attribute list in a search request.

A flaw was found in how Red Hat Directory Server and the 389 Directory Server would handle access controls to certain attributes of an entry. A user with access to the Directory Server could use a series of searches to guess the values of other attributes that they should not be able to see. If a user had access (authenticated or anonymous, depending on whether or not the Directory Server allows anonymous access), they could use this to obtain information that should be restricted due to access controls.
