Impact :

A BGP peer could send a Route-Refresh message with specially crafted ORF
record, which can cause Quagga's bgpd to crash or possibly execute
arbitrary code with the privileges of the user running Quagga's bgpd; a
BGP update AS path request with unknown AS type, or malformed
AS-Pathlimit or Extended-Community attributes could lead to Denial of
Service (daemon crash), an error in bgpd when handling AS_PATH attributes
within UPDATE messages can
be exploited to cause a heap-based buffer overflow resulting in a crash
of the
daemon and disruption of IPv4 routing, two errors in ospf6d and ospfd can
each be exploited to crash the daemon and disrupt IP routing.

Workaround :
