Summary
Updated sssd packages fix security vulnerability
Details

SSSD stores its cached data in an LDAP like local database file using libldb. To lookup cached data LDAP search filters like '(objectClass=user) (name=username)' are used. However, in sysdbsearchuserbyupnres(), the input is not sanitized and allows to manipulate the search filter for cache lookups. This would allow a logged in user to discover the password hash of a different user (CVE-2017-12173).
