Title: DSA-2546-1 freeradius - code execution
Description: 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 the daemon or execute arbitrary code via crafted certificates.
