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).
