Package : qemu
CVE ID : CVE-2018-11806 CVE-2018-12617 CVE-2018-16872 CVE-2018-17958
CVE-2018-18849 CVE-2018-18954 CVE-2018-19364 CVE-2018-19489
CVE-2019-3812 CVE-2019-6778 CVE-2019-9824 CVE-2019-12155
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.
For the stable distribution (stretch), these problems have been fixed in
version 1:2.8+dfsg-6+deb9u6.
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

Package : qemu
Debian Bug : 929067
Vincent Tondellier reported that the qemu update issued as DSA 4454-1
did not correctly backport the support to define the md-clear bit to
allow mitigation of the MDS vulnerabilities. Updated qemu packages are
now available to correct this issue.
For the stable distribution (stretch), this problem has been fixed in
version 1:2.8+dfsg-6+deb9u7.
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
