Three CVEs were assigned (http://seclists.org/oss-sec/2016/q1/52): CVE-2015-8762: The EAP-PWD packet length is not checked before the first byte is dereferenced. A zero-length EAP-PWD packet will cause the module to dereference a NULL pointer, and will cause the server to crash. CVE-2015-8763: The commit message payload length is not validated before the packet is decoded. This can result in a read overflow in the server. The confirm message payload length is not validated before the packet is decoded. This can result in a read overflow in the server. CVE-2015-8764: A strcpy() was used to pack a C string into an EAP-PWD packet. This would result in an over-run of the destination buffer by one byte.
