Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2015-4142 medium priority: Ubuntu including 3 source packages (hostapd, wpa, wpasupplicant), 27 status rows across 9 suites (precise, trusty, upstream, utopic, vivid, wily, xenial, yakkety, zesty): DNE 15, released 8, pending 3, ignored 1.
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.
