Debian DLA-1832-1 : libvirt security update

high Nessus Plugin ID 126220

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Two vulnerabilities were discovered in libvirt, an abstraction API for different underlying virtualisation mechanisms provided by the kernel, etc.

 - CVE-2019-10161: Prevent an vulnerability where readonly clients could use the API to specify an arbitrary path which would be accessed with the permissions of the libvirtd process. An attacker with access to the libvirtd socket could use this to probe the existence of arbitrary files, cause a denial of service or otherwise cause libvirtd to execute arbitrary programs.

 - CVE-2019-10167: Prevent an arbitrary code execution vulnerability via the API where a user-specified binary used to probe the domain's capabilities. read-only clients could specify an arbitrary path for this argument, causing libvirtd to execute a crafted executable with its own privileges.

For Debian 8 'Jessie', these issues have been fixed in libvirt version 1.2.9-9+deb8u7.

We recommend that you upgrade your libvirt packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
