Description Prasad Pandit 2017-09-07 09:59:51 UTC
Quick Emulator(Qemu) built with the PC System Emulator with multiboot feature
support is vulnerable to an OOB r/w memory access issue. It could occur due
to an integer overflow while loading a kernel image during a guest boot.

A user/process could use this flaw to potentially achieve arbitrary code
execution on a host.
