Subject: CVE-2020-27617 QEMU: net: an assert failure via eth_get_gso_type
Hello,
An assert(3) failure issue was found in the networking helper functions of
QEMU. It could occur in the eth_get_gso_type() routine, if a packet does not
have a valid networking L3 protocol (ex. IPv4, IPv6) value. A guest user may
use this flaw to crash the QEMU process on the host resulting in DoS scenario.
