USN-6156-1 fixed a vulnerability in SSSD. In certain environments, not all
packages ended up being upgraded at the same time, resulting in
authentication failures when the PAM module was being used.
This update fixes the problem. We apologize for the inconvenience.
Original advisory details:
It was discovered that SSSD incorrrectly sanitized certificate data used in
LDAP filters. When using this issue in combination with FreeIPA, a remote
attacker could possibly use this issue to escalate privileges.
