CVE-2019-11555

Описание

The EAP-pwd implementation in hostapd (EAP server) before 2.8 and wpa_supplicant (EAP peer) before 2.8 does not validate fragmentation reassembly state properly for a case where an unexpected fragment could be received. This could result in process termination due to a NULL pointer dereference (denial of service). This affects eap_server/eap_server_pwd.c and eap_peer/eap_pwd.c.

Отчет

This issue did not affect the versions of wpa_supplicant as shipped with Red Hat Enterprise Linux 5, and 6 as they did not include support for EAP-pwd. This issue did not affect the versions of wpa_supplicant as shipped with Red Hat Enterprise Linux 7, and 8 as they are not compiled with EAP-pwd enabled. In particular, the CONFIG_EAP_PWD=y option is not set at compile time.
