Package        : qemu
Debian Bug     : 944623

This update for QEMU, a fast processor emulator, backports support to
passthrough the pschange-mc-no CPU flag. The virtualised MSR seen by a
guest is set to show the bug as fixed, allowing to disable iTLB Multihit
mitigations in nested hypervisors (cf. DSA 4564-1).

For the stable distribution (buster), this problem has been fixed in
version 1:3.1+dfsg-8+deb10u3.

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
