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).");
