From d1d4b56fe0c9a4200276d630f62108e1165e0990 Mon Sep 17 00:00:00 2001
From: Maurizio Barbaro <mbarbaro@redhat.com>
Date: Mon, 16 Sep 2024 10:53:53 +0200
Subject: [PATCH] Backport openssl: SSL_select_next_proto buffer overread from 3.2
Ensure that the provided client list is non-NULL and starts with a valid
entry. When called from the ALPN callback the client list should already
have been validated by OpenSSL so this should not cause a problem. When
called from the NPN callback the client list is locally configured and
will not have already been validated. Therefore SSL_select_next_proto
should not assume that it is correctly formatted.
We implement stricter checking of the client protocol list. We also do the
same for the server list while we are about it.
CVE-2024-5535
From: Matt Caswell <matt@openssl.org>
Date: Fri, 31 May 2024 11:14:33 +0100
Merged from: https://github.com/openssl/openssl/pull/24717.
Backported-by: Maurizio Barbaro <mbarbaro@redhat.com>
we did't ported test changes because rely on internal testing framework.
