Synopsis: Moderate: sssd security and bug fix update
Issue Date: 2013-03-19
CVE Numbers: CVE-2013-0287
--

When SSSD was configured as a Microsoft Active Directory client by using
the new Active Directory provider (introduced in SLSA-2013:0508), the
Simple Access Provider ("access_provider = simple" in
"/etc/sssd/sssd.conf") did not handle access control correctly. If any
groups were specified with the "simple_deny_groups" option (in sssd.conf),
all users were permitted access. (CVE-2013-0287)

This update also fixes the following bugs:

* If a group contained a member whose Distinguished Name (DN) pointed out
of any of the configured search bases, the search request that was
processing this particular group never ran to completion. To the user,
this bug manifested as a long timeout between requesting the group data
and receiving the result. A patch has been provided to address this bug
and SSSD now processes group search requests without delays.

* The pwd_expiration_warning should have been set for seven days, but
instead it was set to zero for Kerberos. This incorrect zero setting
returned the "always display warning if the server sends one" error
message and users experienced problems in environments like IPA or Active
Directory. Currently, the value setting for Kerberos is modified and this
issue no longer occurs.
