Detail

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.

Title: DSA-2557-1 hostapd - denial of service
Description: Timo Warns discovered that the internal authentication server of hostapd, a user space IEEE 802.11 AP and IEEE 802.1X/WPA/WPA2/EAP Authenticator, is vulnerable to a buffer overflow when processing fragmented EAP-TLS messages. As a result, an internal overflow checking routine terminates the process. An attacker can abuse this flaw to conduct denial of service attacks via crafted EAP-TLS messages prior to any authentication.
