    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.
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 2.1.10+dfsg-2+squeeze1.
    
    For the testing distribution (wheezy), this problem has will be fixed soon.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 2.1.12+dfsg-1.1.
    
    
    We recommend that you upgrade your freeradius packages.
