CVE-2013-4111 – OpenStack: python-glanceclient failing SSL certificate check

https://notcve.org/view.php?id=CVE-2013-4111

The Python client library for Glance (python-glanceclient) before 0.10.0 does not properly check the preverify_ok value, which prevents the server hostname from being verified with a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate and allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate. La biblioteca cliente Python para Glance (python-glanceclient) anterior a v0.10.0 no comprueba correctamente el valor preverify_ok, lo que impide que el nombre del servidor sea verificado con un nombre de dominio en el nombre común del sujeto (CN) o el campo subjectAltName de un certificado X.509, permitiendo a los atacantes de hombre-en-medio (man-in-the-middle) falsificar servidores SSL mediante un certificado valido de su elección. • http://lists.opensuse.org/opensuse-updates/2013-08/msg00019.html http://rhn.redhat.com/errata/RHSA-2013-1200.html http://secunia.com/advisories/54313 http://secunia.com/advisories/54525 http://www.ubuntu.com/usn/USN-2004-1 https://bugs.launchpad.net/ossa/+bug/1192229 https://github.com/openstack/python-glanceclient/blob/master/doc/source/index.rst https://access.redhat.com/security/cve/CVE-2013-4111 https://bugzilla.redhat.com/show_bug.cgi?id=989738 • CWE-20: Improper Input Validation CWE-295: Improper Certificate Validation •
