From b1fd71de03ae3843ac556d9b726b5f3b2441c3ed Mon Sep 17 00:00:00 2001

Subject: [PATCH] Add whitelisting for package and service module
**security issue** (CVE-2020-1738)
When 'use' parameter is not used in package and service module,
ansible relies on ansible facts such as 'pkg_mgr' and 'service_mgr'.
This would allow arbitrary code execution on the managed node.
Fix is added by adding a whitelist of allowed package manager modules and
service manager modules to avoid arbitrary code execution on the managed node.
Fixes: #67796
Signed-off-by: Abhijeet Kasurde <akasurde@redhat.com>
