Description Pedro Sampaio 2018-08-09 19:44:32 UTC
An issue was discovered in rsn_supp/wpa.c in wpa_supplicant 2.0 through 2.6. Under certain conditions, the integrity of EAPOL-Key messages is not checked, leading to a decryption oracle. An attacker within range of the Access Point and client can abuse the vulnerability to recover sensitive information.



Comment 3 Stefan Cornelius 2018-10-09 14:17:28 UTC

Red Hat Virtualization images include wpa_supplicant as a component from the base Red Hat Enterprise Linux operating system, but use of Red Hat Virtualization on a wireless network is neither recommended nor supported. A future update may address this issue.

This issue affects the versions of wpa_supplicant as shipped with Red Hat Enterprise Linux 6 and 7.

Red Hat Enterprise Linux 6 is now in Maintenance Support 2 Phase of the support and maintenance life cycle. This has been rated as having a security impact of Moderate, and is not currently planned to be addressed in future updates. For additional information, refer to the Red Hat Enterprise Linux Life Cycle: https://access.redhat.com/support/policy/updates/errata/.
