First published: Mon May 21 2018(Updated: )
A potential integer overflow issue was found in the networking back-end of QEMU. It could occur while receiving packets, because it accepted packets with large size value. Such overflow could lead to OOB buffer access issue. A user inside guest could use this flaw to crash the QEMU process resulting in DoS.
