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

This script is Copyright (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

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

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).

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.
