CVE-2019-9495

The implementations of EAP-PWD in hostapd and wpasupplicant are vulnerable to side-channel attacks as a result of cache access patterns. All versions of hostapd and wpasupplicant with EAP-PWD support are vulnerable. The ability to install and execute applications is necessary for a successful attack. Memory access patterns are visible in a shared cache. Weak passwords may be cracked. Versions of hostapd/wpasupplicant 2.7 and newer, are not vulnerable to the timing attack described in CVE-2019-9494. Both hostapd with EAP-pwd support and wpasupplicant with EAP-pwd support prior to and including version 2.7 are affected.
