Mageia: 2019-0176 Critical: FreeRADIUS Authentication Issues

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
Summary
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).
