First published: Tue May 22 2018(Updated: )
An integer overflow issue was found in the NE200 NIC emulation. It could occur while receiving packets from the network, if the size value was greater than INT_MAX. Such overflow would lead to stack buffer overflow issue. A user inside guest could use this flaw to crash the QEMU process, resulting in DoS scenario.
