Description Murray McAllister 2014-07-11 01:40:20 EDT

libndp provides a library for the IPv6 Neighbor Discovery Protocol. A buffer overflow flaw was found in the ndp_msg_opt_dnssl_domain() function when handling the DNS Search List (DNSSL) in IPv6 router advertisements. A malicious router or man-in-the-middle attacker could use this flaw to cause an application using libndp to crash or, potentially, execute arbitrary code.
