Vulnerability Title
GoPacket's sFlow ExtendedGatewayFlow decoder: unbounded attacker-controlled allocation (104-byte UDP datagram -> up to 16 GiB make) -> unauthenticated remote DoS
Vulnerability Description
gopacket provides packet processing capabilities for Go. In version 1.6.0 and earlier, the sFlow ExtendedGatewayFlow decoder in layers/sflow.go reads an attacker-controlled 32-bit community count and AS path member count and sizes a slice allocation from those counts without bounding them against the bytes remaining in the datagram, so a 104-byte UDP datagram can drive an allocation of up to 16 GiB and cause an unauthenticated remote denial of service. This issue is fixed in version 1.6.1.
