CVE-2016-7091  (opens in a new tab)
CWE-200  (opens in a new tab)

How to fix?

Upgrade RHEL:7 sudo to version 0:1.8.6p7-20.el7 or higher.
This issue was patched in RHSA-2016:2593.

NVD Description

Note: Versions mentioned in the description apply only to the upstream sudo package and not the sudo package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

sudo: It was discovered that the default sudo configuration on Red Hat Enterprise Linux and possibly other Linux implementations preserves the value of INPUTRC which could lead to information disclosure. A local user with sudo access to a restricted program that uses readline could use this flaw to read content from specially formatted files with elevated privileges provided by sudo.
