   An update that fixes two vulnerabilities is now available.

Description:

   wpa_supplicant was updated to fix two security issues.

   These security issues were fixed:
   - CVE-2015-4142: Integer underflow in the WMM Action frame parser in
     hostapd and wpa_supplicant, when used for AP mode MLME/SME
     functionality, allowed remote attackers to cause a denial of service
     (crash) via a crafted frame, which triggers an out-of-bounds read
     (bsc#930078).
   - CVE-2015-4141: The WPS UPnP function in hostapd, when using WPS AP, and
     wpa_supplicant, when using WPS external registrar (ER), allowed remote
     attackers to cause a denial of service (crash) via a negative chunk
     length, which triggered an out-of-bounds read or heap-based buffer
     overflow (bsc#930077).
