RHEL 5 : sudo (RHSA-2017:1381)

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing a security update.

Description :

An update for sudo is now available for Red Hat Enterprise Linux 5
Extended Lifecycle Support.

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.

The sudo packages contain the sudo utility which allows system
administrators to provide certain users with the permission to execute
privileged commands, which are used for system management purposes,
without having to log in as root.

Security Fix(es) :

* A flaw was found in the way sudo parsed tty information from the
process status file in the proc filesystem. A local user with
privileges to execute commands via sudo could use this flaw to
escalate their privileges to root. (CVE-2017-1000367)

Red Hat would like to thank Qualys Security for reporting this issue.
