Debian DSA-4338-1 : qemu - security update

critical Nessus Plugin ID 118895

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the qemu packages.

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