Build Update for libvirt/libvirt ------------------------------------- Build: #607 Status: Still Failing Duration: 1 hour, 12 minutes, and 2 seconds Commit: dc6c417 (v3.7-maint) Author: Daniel P. Berrange Message: 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.
