Subject: [Buildroot] [PATCH] package/wpa_supplicant: add upstream 2021-1 security fix
Date: Tue,  2 Mar 2021 22:59:43 +0100	[thread overview]
Message-ID: <20210302215943.14131-1-peter@korsgaard.com> (raw)

Fixes the following security issue:

- wpa_supplicant P2P provision discovery processing vulnerability (no CVE
  yet)

A vulnerability was discovered in how wpa_supplicant processes P2P
(Wi-Fi Direct) provision discovery requests. Under a corner case
condition, an invalid Provision Discovery Request frame could end up
reaching a state where the oldest peer entry needs to be removed. With
a suitably constructed invalid frame, this could result in use
(read+write) of freed memory. This can result in an attacker within
radio range of the device running P2P discovery being able to cause
unexpected behavior, including termination of the wpa_supplicant process
and potentially code execution.

For more details, see the advisory:
https://w1.fi/security/2021-1/wpa_supplicant-p2p-provision-discovery-processing-vulnerability.txt
