Synopsis: Low: wpa_supplicant security and enhancement update
Advisory ID: SLSA-2015:1439-1
Issue Date: 2015-07-22
CVE Numbers: CVE-2015-4142
--

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.

After installing this update, the wpa_supplicant service will be restarted
automatically.
