Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.04 LTS - Ubuntu 12.04 LTS - Ubuntu 10.04 LTS

Summary:

wpa_supplicant could be made to run programs if it received specially crafted network traffic.

Software Description: - wpa: client support for WPA and WPA2 - wpasupplicant: client support for WPA and WPA2

Details:

Jouni Malinen discovered that the wpa_cli tool incorrectly sanitized strings when being used with action scripts. A remote attacker could possibly use this issue to execute arbitrary commands.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.04 LTS:
wpasupplicant 2.1-0ubuntu1.1

Ubuntu 12.04 LTS:
wpasupplicant 0.7.3-6ubuntu2.3

Title: DSA-3052-1 wpa - security update
Description: Jouni Malinen discovered an input sanitization issue in the wpa_cli and hostapd_cli tools included in the wpa package. A remote wifi system within range could provide a crafted string triggering arbitrary code execution running with privileges of the affected wpa_cli or hostapd_cli process.

Title: RHSA-2014:1956 -- wpa_supplicant security update (Moderate)
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.
