CVE-2018-7550

Priority
Description
The load_multiboot function in hw/i386/multiboot.c in Quick Emulator (aka
QEMU) allows local guest OS users to execute arbitrary code on the QEMU
host via a mh_load_end_addr value greater than mh_bss_end_addr, which
triggers an out-of-bounds read or write memory access.
