SUSE SLED11 / SLES11 Security Update : wpa_supplicant (SUSE-SU-2015:2221-1)

Medium Nessus Plugin ID 87279


The remote SUSE host is missing one or more security updates.


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).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
