Virtuozzo 7 : sudo / sudo-devel (VZLSA-2016-2872)

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


Synopsis :

The remote Virtuozzo host is missing a security update.

Description :

An update for sudo is now available for Red Hat Enterprise Linux 6 and
Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Moderate. 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) :

* It was discovered that the sudo noexec restriction could have been
bypassed if application run via sudo executed system(), popen(), or
wordexp() C library functions with a user-supplied argument. A local
user permitted to run such application via sudo with noexec
restriction could use these flaws to execute arbitrary commands with
elevated privileges. (CVE-2016-7032, CVE-2016-7076)

These issues were discovered by Florian Weimer (Red Hat).

Note that Tenable Network Security has attempted to extract the
preceding description block directly from the corresponding Red Hat
security advisory. Virtuozzo provides no description for VZLSA
advisories. Tenable has attempted to automatically clean and format
it as much as possible without introducing additional issues.
