Vulnerability Name:

CCN-116081

Published:2016-08-10
Updated:2016-08-10
Summary:QEMU could allow a local attacker to obtain sensitive information, caused by improper validation of IP Header Length values by the Vmxnet3 Device Emulator. By using a specially-crafted IP Header, an attacker could exploit this vulnerability to obtain sensitive information.
