Debian DSA-2557-1 : hostapd - buffer overflow

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...

Debian DSA-2546-1 : freeradius - stack-based buffer overflows

Timo Warns discovered that the EAP-TLS handling of FreeRADIUS, a high-performance and highly configurable RADIUS server, is not properly performing length checks on user-supplied input before copying to a local stack buffer. As a result, an unauthenticated attacker can exploit this flaw to crash...
