Vulnerability CVE-2015-5315

Vulnerability Name:

CVE-2015-5315 (CCN-139832)

Assigned:

2015-07-01

Published:

2015-07-01

Updated:

2018-03-21

Summary:

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.
