Vigil@nce - Quagga: denial of service via route announce
November 2012 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An attacker may send a malicious IPv6 route announcement to Quagga
in order to stop it.
– Impacted products: Quagga
– Severity: 2/4
– Creation date: 13/11/2012
DESCRIPTION OF THE VULNERABILITY
The product Quagga Routing Suite implements OSPF routing for IPv6.
However, when a neighbour router announces to a router running
Quagga a route with a network prefix length greater than 64 bits,
the ospf6d daemon detects an assertion failure and stops.
An attacker may therefore send a malicious IPv6 route announcement
to Quagga in order to stop it.
