DESCRIPTION:
A security issue has been reported in SSSD, which can be exploited by
malicious people to bypass certain security restrictions.

The security issue exists when performing authentication with an LDAP
server through a service that utilizes pam_authenticate. This can be
exploited to login as an arbitrary user by providing an empty
password.

Successful exploitation requires the LDAP server to allow
unauthenticated binds.

The security issue is reported in version 1.3.0. Other versions may
also be affected.

SOLUTION:
Fixed in the Trac repository.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Ted Brunell.
