An out-of-bounds access issue was found in the SLiRP user networking implementation of QEMU. It could occur while processing ARP/NCSI packets, if the packet length was shorter than required to accommodate respective protocol headers and payload. A privileged guest user may use this flaw to potentially leak host information bytes.
