RHEL 5 : sudo (RHSA-2017:1381)

medium Nessus Plugin ID 100587

Language:

Synopsis

The remote Red Hat host is missing a security update for sudo.

Description

The remote Redhat Enterprise Linux 5 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2017:1381 advisory.

 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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL sudo package based on the guidance in RHSA-2017:1381.
