    Summary: Updated freeradius packages fix security vulnerability

    Details: An attacker can reflect the received scalar and element from the server in it's own commit message, and subsequently reflect the confirm value as well. This causes the adversary to successfully authenticate as the victim (CVE-2019-11234). An invalid curve attack allows an attacker to authenticate as any user (without knowing the password). The problem is that on the reception of an EAP-PWD Commit frame, FreeRADIUS doesn't verify whether the received elliptic curve point is valid (CVE-2019-11235).
