    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).
