RHEL 7 : wpa_supplicant (RHSA-2014:1956)

This script is Copyright (C) 2014-2017 Tenable Network Security, Inc.

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

An updated wpa_supplicant package that fixes one security issue is now
available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate
security impact. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available from the
CVE link in the References section.

The wpa_supplicant package contains an 802.1X Supplicant with support
for WEP, WPA, WPA2 (IEEE 802.11i / RSN), and various EAP
authentication methods. It implements key negotiation with a WPA
Authenticator for client stations and controls the roaming and IEEE
802.11 authentication and association of the WLAN driver.

A command injection flaw was found in the way the wpa_cli utility
executed action scripts. If wpa_cli was run in daemon mode to execute
an action script (specified using the -a command line option), and
wpa_supplicant was configured to connect to a P2P group, malicious P2P
group parameters could cause wpa_cli to execute arbitrary code.

Red Hat would like to thank Jouni Malinen for reporting this issue.

All wpa_supplicant users are advised to upgrade to this updated
package, which contains a backported patch to correct this issue.
