Red Hat: 2014:1956-01: wpa_supplicant: Moderate Advisory
Summary
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.
