RHEL 7 : ansible (RHSA-2017:1499)

Synopsis :

The remote Red Hat host is missing a security update.

Description :

An update for ansible is now available for Red Hat Storage Console 2
for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

Ansible is a simple model-driven configuration management, multi-node
deployment, and remote-task execution system. Ansible works over SSH
and does not require any software or daemons to be installed on remote
nodes. Extension modules can be written in any language and are
transferred to managed machines automatically.

Security Fix(es) :

* An input validation vulnerability was found in Ansible's handling of
data sent from client systems. An attacker with control over a client
system being managed by Ansible, and the ability to send facts back to
the Ansible server, could use this flaw to execute arbitrary code on
the Ansible server using the Ansible server privileges.
(CVE-2017-7466)

* An input validation flaw was found in Ansible, where it fails to
properly mark lookup-plugin results as unsafe. If an attacker could
control the results of lookup() calls, they could inject Unicode
strings to be parsed by the jinja2 templating system, resulting in
code execution. By default, the jinja2 templating language is now
marked as 'unsafe' and is not evaluated. (CVE-2017-7481)

These issues were discovered by Evgeni Golov (Red Hat).
