"Some issues have been found in qemu, a fast processor emulator.

All issues are related to assertion failures, out-of-bounds access
failures or bad handling of return codes.

For Debian 9 stretch, these problems have been fixed in version
1:2.8+dfsg-6+deb9u12.

We recommend that you upgrade your qemu packages.

For the detailed security status of qemu please refer to its security
tracker page at: https://security-tracker.debian.org/tracker/qemu
