Description

The implementations of SAE in hostapd and wpa_supplicant are vulnerable to side channel attacks as a result of observable timing differences and cache access patterns. An attacker may be able to gain leaked information from a side channel attack that can be used for full password recovery. Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.7 are affected.

Affected configurations

• w1.fi hostapd (<= 2.7) • w1.fi wpa supplicant (<= 2.7) • fedoraproject fedora 28 • fedoraproject fedora 29 • fedoraproject fedora 30 • opensuse backports sle 15.0 • opensuse leap 15.1 • synology radius server 3.0 • synology router manager (< 1.2.3-8087) • freebsd freebsd 11.2 • freebsd freebsd 12.0
