Synopsis

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

Description

Multiple security issues were discovered in QEMU, a fast processor emulator, which could result in denial of service, the execution of arbitrary code or information disclosure.

In addition this update backports support to passthrough the new md-clear CPU flag added in the intel-microcode update shipped in DSA 4447 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+deb9u6.
