Discovery 2012-06-04

CERT reports:

If a pre-configured BGP peer sends a specially-crafted OPEN message with a malformed ORF capability TLV, Quagga bgpd process will erroneously try to consume extra bytes from the input packet buffer. The process will detect a buffer overrun attempt before it happens and immediately terminate with an error message. All BGP sessions established by the attacked router will be closed and its BGP routing disrupted.
