It was found that sssd’s sysdb_search_user_by_upn_res() function before
1.16.0 did not sanitize requests when querying its local cache and was
vulnerable to injection. In a centralized login environment, if a password
hash was locally cached for a given user, an authenticated attacker could
use this flaw to retrieve it.
