-Subject: [PATCH] EAP-pwd peer: Fix last fragment length validation
-
-All but the last fragment had their length checked against the remaining
-room in the reassembly buffer. This allowed a suitably constructed last
-fragment frame to try to add extra data that would go beyond the buffer.
-The length validation code in wpabuf_put_data() prevents an actual
-buffer write overflow from occurring, but this results in process
-termination. (CVE-2015-5315)
