AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions Qemu emulator version 3.0.0 and earlier

Description The issue is related to an integer overflow that could lead to a buffer overflow problem. This occurs when receiving packets over the network, specifically with the NE2000 NIC emulation support. A user inside the guest could exploit this flaw to crash the Qemu process, resulting in a denial of service (DoS).

Recommendations For Qemu emulator version 3.0.0 and earlier, consider disabling the NE2000 NIC emulation support as a temporary workaround until a patch is available. Restrict access to the network to minimize the risk of exploitation.
