Debian Security Advisory 1788-1 – It was discovered that Quagga, an IP routing daemon, could no longer process the Internet routing table due to broken handling of multiple 4-byte AS numbers in an AS path. If such a prefix is received, the BGP daemon crashes with an assert failure, leading to a denial of service.
