Statement: 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 SAE (Simultaneous Authentication of Equals) nor 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 SAE (Simultaneous Authentication of Equals) nor with EAP-pwd enabled. In particular, the CONFIG_SAE=y and CONFIG_EAP_PWD=y options are not set at compile time. This bug is now closed. Further updates for individual products will be reflected on the CVE page(s): https://access.redhat.com/security/cve/cve-2019-13377 |
