Slackware 15.0: 2024-059-01 Critical: wpa_supplicant Authentication Bypass

slackware
Calendar Grey February 28, 2024
Dist Slackware Esm H88
Latest wpa_supplicant updates available for Slackware 15.0 to resolve a critical authentication bypass vulnerability. Immediate upgrade is advised.
New wpa_supplicant packages are available for Slackware 15.0 and -current to fix a security issue

Summary

Here are the details from the Slackware 15.0 ChangeLog: patches/packages/wpa_supplicant-2.10-i586-2_slack15.0.txz: Rebuilt. Patched the implementation of PEAP in wpa_supplicant to prevent an authentication bypass. For a successful attack, wpa_supplicant must be configured to not verify the network's TLS certificate during Phase 1 authentication, and an eap_peap_decrypt vulnerability can then be abused to skip Phase 2 authentication. The attack vector is sending an EAP-TLV Success packet instead of starting Phase 2. This allows an adversary to impersonate Enterprise Wi-Fi networks. For more information, see: https://www.cve.org/CVERecord?id=CVE-2023-52160 (* Security fix *)
