  "details" : [ "eth_get_gso_type in net/eth.c in QEMU 4.2.1 allows guest OS users to trigger an assertion failure. A guest can crash the QEMU process via packet data that lacks a valid Layer 3 protocol.", "An assert(3) failure flaw was found in the networking helper functions of QEMU. This vulnerability can occur in the eth_get_gso_type() routine if a packet does not have a valid networking L3 protocol (ex. IPv4, IPv6) value. This flaw allows a guest user to crash the QEMU process on the host, resulting in a denial of service." ],
