Red Hat Product Errata RHSA-2010:0590 0 normal SHIPPED_LIVE Low: Red Hat Directory Server security and enhancement update 2010-08-03 20:12:56 UTC

Description Tomas Hoger 2010-06-25 13:27:39 UTC
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:
