Berrange <berrange@redhat.com> -Date: Thu, 5 Oct 2017 17:54:28 +0100 -Subject: [PATCH] qemu: ensure TLS clients always verify the server certificate - -The default_tls_x509_verify (and related) parameters in qemu.conf -control whether the QEMU TLS servers request & verify certificates -from clients. This works as a simple access control system for -servers by requiring the CA to issue certs to permitted clients. -This use of client certificates is disabled by default, since it -requires extra work to issue client certificates. - -Unfortunately the code was using this configuration parameter when -setting up both TLS clients and servers in QEMU. The result was that -TLS clients for character devices and disk devices had verification -turned off, meaning they would ignore errors while validating the -server certificate. - -This allows for trivial MITM attacks between client and server, -as any certificate returned by the attacker will be accepted by -the client. - -This is assigned CVE-2017-1000256 / LSN-2017-0002 - -Reviewed-by: Eric Blake <eblake@redhat.com> -Signed-off-by: Daniel P.
