CVE-2017-6058
Buffer overflow in NetRxPkt::ehdr_buf in hw/net/net_rx_pkt.c in QEMU (aka Quick Emulator), when the VLANSTRIP feature is enabled on the vmxnet3 device, allows remote attackers to cause a denial of service (out-of-bounds access and QEMU process crash)…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.92%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
