These are all security issues fixed in the hostapd-2.6-1.1 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the wpa_supplicant-2.6-1.1 package on the GA media of openSUSE Tumbleweed.

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).

This update for wpa_supplicant fixes the following issues:

• CVE-2015-4141: WPS UPnP vulnerability with HTTP chunked transfer encoding. (bnc#930077)

• CVE-2015-4143: EAP-pwd missing payload length validation. (bnc#930079)
• CVE-2015-5310: Ignore Key Data in WNM Sleep Mode Response frame if no PMF in use. (bsc#952254)

Integer underflow in the WMM Action frame parser in hostapd 0.5.5 through 2.4 and wpa_supplicant 0.7.0 through 2.4, when used for AP mode MLME/SME functionality, allows remote attackers to cause a denial of service (crash) via a crafted frame, which triggers an out-of-bounds read.

Kostya Kortchinsky discovered multiple flaws in wpa_supplicant and hostapd. A remote attacker could use these issues to cause wpa_supplicant or hostapd to crash, resulting in a denial of service. (CVE-2015-4141, CVE-2015-4142, CVE-2015-4143, CVE-2015-4144, CVE-2015-4145, CVE-2015-4146)
