From mboxrd@z Thu Jan 1 00:00:00 1970 From: Peter Korsgaard Date: Tue, 2 Mar 2021 22:59:43 +0100 Subject: [Buildroot] [PATCH] package/wpa_supplicant: add upstream 2021-1 security fix Message-ID: <20210302215943.14131-1-peter@korsgaard.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net 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.
