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.

Solution(s)

  • freebsd-upgrade-base-11_2-release-p9
  • freebsd-upgrade-base-12_0-release-p3
  • freebsd-upgrade-package-hostapd
  • freebsd-upgrade-package-wpa_supplicant
