CentOS 7 : wpa_supplicant (CESA-2014:1956)

medium Nessus Plugin ID 79726

Language:

Synopsis

The remote CentOS host is missing a security update.

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.
(CVE-2014-3686)

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.

Solution

Update the affected wpa_supplicant package.
