Denial of Service in EAP-pwd Message Reassembly

CVE-2015-5315 · MEDIUM Severity

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

The eap_pwd_process function in eap_peer/eap_pwd.c in wpa_supplicant 2.x before 2.6 does not validate that the reassembly buffer is large enough for the final fragment when EAP-pwd is enabled in a network configuration profile, which allows remote attackers to cause a denial of service (process termination) via a large final fragment in an EAP-pwd message.
