From ${URL} : Quick Emulator(Qemu) built with the CCID Card device emulator support is vulnerable to an integer overflow flaw. It could occur while passing message via command/responses packets to and from the host. A privileged user inside guest could use this flaw to crash the Qemu process on host resulting in DoS.
