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.
Qemu emulator built with the NE2000 NIC emulation support is vulnerable to an integer overflow, which could lead to buffer overflow issue. It could occur when receiving packets over the network.
A user inside guest could use this flaw to crash the Qemu process resulting in DoS.
