CVE-2014-3554: libndp buffer overflow

Good morning,

The below was previously sent to the distros list. A patch is available from https://bugzilla.redhat.com/attachment.cgi?id=917255

libndp (libndp.org) provides a library for the IPv6 Neighbor Discovery Protocol. Andrew Ayer discovered a buffer overflow flaw 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. (CVE-2014-3554)

Please credit Andrew Ayer with the discovery.

Cheers,
