FreeBSD : quagga -- stack overflow and DoS vulnerabilities (167953a4-b01c-11df-9a98-0015587e2cc1)

Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

The Red Hat security team reported two vulnerabilities :

A stack-based 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.

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).
