Hello,
An integer overflow issue was found in the QEMU Guest Agent in QEMU, while
reading argument list passed to the 'guest-exec' qmp command. An attacker
could exploit this by sending a crafted QMP command to the agent via a
listening socket to trigger the overflow. It may crash the QEMU guest agent,
resulting in DoS.
