Patches checked into Mageia 3 and Mageia 4 SVN.

Patched packages uploaded for Mageia 3 and Mageia 4.

Advisory:
========================

Updated wpa_supplicant and hostapd packages fix security vulnerability:

A vulnerability was found in the mechanism wpa_cli and hostapd_cli use
for executing action scripts. An unsanitized string received from a
remote device can be passed to a system() call resulting in arbitrary
command execution under the privileges of the wpa_cli/hostapd_cli
process (which may be root in common use cases) (CVE-2014-3686).

Using the Mageia wpa_supplicant package, systems are exposed to the
vulnerability if operating as a WPS registrar.

The Mageia hostapd package was not vulnerable with the configuration with
which it was built, but if a sysadmin had rebuilt it with WPS enabled, it
would be vulnerable.

wpa_supplicant-2.0-2.1.mga4 from core updates testing
Installed these afterwards from core updates testing
wpa_supplicant-gui-2.0-2.1.mga4
hostapd-2.0-2.1.mga4
The latter pulled in lib64nl1 from core release.

Invoked wpa_gui to try to get some clue about what to do.  Looks like a network manager but have no idea where to go with that and it may not be relevant given that the advisory points to the *_cli as being vulnerable.

Will look at the link posted above to see what action scripts are.

I don't have a 32-bit install with wifi, so I'll leave that to someone else to test.

Testing on Mageia4-32 (as advised by Claire Robinson, disabled networkmanager service, rebooted, otherwise I was not able to connect through wifi)

With current packages :
---------------------

wpa_supplicant-2.0-2.mga4
wpa_supplicant-gui 2.0.-2.mga4

Could connect through encrypted and non-encrypted wifi.

wpa_gui (run as root) showed :

Authentification : NONE
Encryption : NONE

- on encrypted
Authentification : WPA-PSK
Encryption : CCMP + TKIP


With update-testing :
-------------------

wpa_supplicant-2.0-2.1.mga4
