Description d'origine La description telle que publiée par la source (souvent en anglais).
A NULL pointer dereference flaw was found in the floppy disk emulator of QEMU.

This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.
