Denial of Service Vulnerability in hostapd 2.x

CVE-2015-5314 · MEDIUM Severity

AV:N/AC:M/AU:N/C:N/I:N/A:P

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.
