DESCRIPTION:
A vulnerability has been reported in Quagga, which can be exploited
by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error in the
"bgp_capability_orf()" function when parsing OPEN messages containing
an ORF capability TLV. This can be exploited to cause a buffer
overflow via a specially crafted packet.
Successful exploitation requires control of a pre-configured BGP
peer.
The vulnerability is reported in versions 0.99.20.1 and prior.
SOLUTION:
Restrict access to trusted BGP peers only.
