Description Tomas Hoger 2007-09-11 09:10:32 UTC 
From Quagga 0.99.9 release notes:

This release fixes two potential DoS conditions in bgpd, reported by Mu
Security, where a bgpd could be crashed if a peer sent a malformed OPEN message
or a malformed COMMUNITY attribute. Only configured peers can do this, hence we
consider these issues to be very low impact.
