Last modified

CVE-2012-4445 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 4.22% chance of exploitation in the next 30 days.
