Important CentOS wpa_supplicant Security Update
An updated wpa_supplicant package that fixes one security issue and adds
one enhancement is now available for Red Hat Enterprise Linux 6.
Red Hat Product Security has rated this update as having Low security
impact. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available from the CVE link in the
The wpa_supplicant package contains an 802.1X Supplicant with support for
WEP, WPA, WPA2 (IEEE 802.11i / RSN), and various EAP authentication
methods. It implements key negotiation with a WPA Authenticator for client
stations and controls the roaming and IEEE 802.11 authentication and
association of the WLAN driver.
An integer underflow flaw, leading to a buffer over-read, was found in the
way wpa_supplicant handled WMM Action frames. A specially crafted frame
could possibly allow an attacker within Wi-Fi radio range to cause
wpa_supplicant to crash. (CVE-2015-4142)
This update includes the following enhancement:
* Prior to this update, wpa_supplicant did not provide a way to require the
host name to be listed in an X.509 certificate's Common Name or Subject
Alternative Name, and only allowed host name suffix or subject substring
checks. This update introduces a new configuration directive,
'domain_match', which adds a full host name check. (BZ#1186806)
All wpa_supplicant users are advised to upgrade to this updated package,
which contains a backported patch to correct this issue and adds this
enhancement. After installing this update, the wpa_supplicant service will
be restarted automatically.
