CVE-2015-4146

Published: 01 June 2015

The EAP-pwd peer implementation in hostapd and wpa_supplicant 1.0 through 2.4 does not clear the L (Length) and M (More) flags before determining if a response should be fragmented, which allows remote attackers to cause a denial of service (crash) via a crafted message.
