CVE-2015-5314 (opens in a new tab)How to fix?
Upgrade Ubuntu:15.04 wpa to version 2.1-0ubuntu7.3 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream wpa package and not the wpa package as distributed by Ubuntu.
See How to fix? for Ubuntu:15.04 relevant fixed versions and status.
The eap_pwd_process function in eap_server/eap_server_pwd.c in hostapd 2.x before 2.6 does not validate that the reassembly buffer is large enough for the final fragment when used with (1) an internal EAP server or (2) a RADIUS server and EAP-pwd is enabled in a runtime configuration, which allows remote attackers to cause a denial of service (process termination) via a large final fragment in an EAP-pwd message.
