FreeBSD : quagga -- BGP OPEN denial of service vulnerability (1e14d46f-af1f-11e1-b242-00215af774f0)
Low Nessus Plugin ID 59380
SynopsisThe remote FreeBSD host is missing one or more security-related updates.
DescriptionCERT 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.
SolutionUpdate the affected packages.
