NVD Description

Note: Versions mentioned in the description apply only to the upstream wpa package and not the wpa package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

Heap-based buffer overflow in the eap_server_tls_process_fragment function in eap_server_tls_common.c in the EAP authentication server in hostapd 0.6 through 1.0 allows remote attackers to cause a denial of service (crash or abort) via a small "TLS Message Length" value in an EAP-TLS message with the "More Fragments" flag set.
