Title:
pysaml2 version in global requirements must be updated to 4.5.0
Status in OpenStack Identity (keystone):
Fix Committed
Status in OpenStack Global Requirements:
New
Bug description:
As per security vulnerability CVE-2016-10149, XML External Entity
(XXE) vulnerability in PySAML2 4.4.0 and earlier allows remote
attackers to read arbitrary files via a crafted SAML XML request or
response and it has a CVSS v3 Base Score of 7.5.
The above vulnerability has been fixed in version 4.5.0 as per
https://github.com/rohe/pysaml2/issues/366. The latest version of
pysaml2 (https://pypi.python.org/pypi/pysaml2/4.5.0) has this fix.
However, the global requirements has the version set to < 4.0.3
https://github.com/openstack/requirements/blob/master/global-requirements.txt#L230
pysaml2>=4.0.2,<4.0.3
https://github.com/openstack/requirements/blob/master/upper-constraints.txt#L347
pysaml2===4.0.2
The version of pysaml2 supported for OpenStack should be updated such
that OpenStack deployments are not vulnerable to the above mentioned
CVE.
pysaml2 is used by OpenStack Keystone for identity Federation. This
bug in itself is not a security vulnerability but not fixing this bug
causes OpenStack deployments to be vulnerable.
