    Synopsis:          Moderate: wpa_supplicant security update
    Advisory ID:       RHSA-2014:1956-01
    Product:           Red Hat Enterprise Linux
    Advisory URL:      https://rhn.redhat.com/errata/RHSA-2014-1956.html
    Issue date:        2014-12-03
    CVE Names:         CVE-2014-3686 
    =====================================================================
    
    1. Summary:
    
    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.
    
    2. Relevant releases/architectures:
    
    Red Hat Enterprise Linux Client (v. 7) - x86_64
    Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64
    Red Hat Enterprise Linux Server (v. 7) - ppc64, s390x, x86_64
    Red Hat Enterprise Linux Workstation (v. 7) - x86_64
    
    3. Description:
    
    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.
    
    4. Solution:
    
    Before applying this update, make sure all previously released errata
    relevant to your system have been applied.
