Subject: CVE Request -- Quagga (bgpd) [two ids] -- 1, Stack buffer overflow
 by processing crafted Refresh-Route msgs 2, NULL ptr deref by parsing certain
 AS paths by BGP update request

Hi Steve, vendors,

   Quagga upstream has released latest vQuagga 0.99.17 version, addressing two security flaws:

A, Stack buffer overflow by processing certain Route-Refresh messages

   A stack buffer overflow flaw was found in the way Quagga's bgpd daemon
   processed Route-Refresh messages. A configured Border Gateway Protocol
   (BGP) peer could send a Route-Refresh message with specially-crafted
   Outbound Route Filtering (ORF) record, which would cause the master BGP
   daemon (bgpd) to crash or, possibly, execute arbitrary code with the
   privileges of the user running bgpd.

B, DoS (crash) while processing certain BGP update AS path messages

   A NULL pointer dereference flaw was found in the way Quagga's bgpd daemon
   parsed paths of autonomous systems (AS). A configured BGP peer could send
   a BGP update AS path request with unknown AS type, which could lead to
   denial of service (bgpd daemon crash).

Could you allocate CVE ids for these?

Thanks && Regards, Jan.
