Debian DSA-4506-1 : qemu - security update

critical Nessus Plugin ID 128180
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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 bypass of ACLs.

In addition this update fixes a regression which could cause NBD connections to hang.

Solution

Upgrade the qemu packages.

For the oldstable distribution (stretch), these problems have been fixed in version 1:2.8+dfsg-6+deb9u8.
