Debian DSA-4469-1 : libvirt - security update

high Nessus Plugin ID 126128

Language:

Synopsis

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

Description

Two vulnerabilities were discovered in Libvirt, a virtualisation abstraction library, allowing an API client with read-only permissions to execute arbitrary commands via the virConnectGetDomainCapabilities API, or read or execute arbitrary files via the virDomainSaveImageGetXMLDesc API.

Additionally the libvirt's cpu map was updated to make addressing CVE-2018-3639, CVE-2017-5753, CVE-2017-5715, CVE-2018-12126, CVE-2018-12127, CVE-2018-12130 and CVE-2019-11091 easier by supporting the md-clear, ssbd, spec-ctrl and ibpb CPU features when picking CPU models without having to fall back to host-passthrough.

Solution

Upgrade the libvirt packages.

For the stable distribution (stretch), these problems have been fixed in version 3.0.0-4+deb9u4.
