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.
