Package        : qemu
CVE ID         : CVE-2018-10839 CVE-2018-17962 CVE-2018-17963
Debian Bug     : 908682 910431 911468 911469

Integer overflows in the processing of packets in network cards emulated
by QEMU, a fast processor emulator, could result in denial of service.

In addition this update backports support to passthrough the new CPU
features added in the intel-microcode update shipped in DSA 4273 to
x86-based guests.

For the stable distribution (stretch), these problems have been fixed in
version 1:2.8+dfsg-6+deb9u5.

We recommend that you upgrade your qemu packages.

For the detailed security status of qemu please refer to
its security tracker page at:
