From ${URL} : 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 while loading a kernel image during a guest boot if muliboot head addresses mh_load_end_addr was greater than mh_bss_end_addr. A user/process could use this flaw to potentially achieve arbitrary code execution on a host. Upstream patch: --------------- -> https://lists.gnu.org/archive/html/qemu-devel/2018-02/msg06890.html @maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
