Synopsis

Multiple vulnerabilities have been found in Xen, the worst of which could lead to the execution of arbitrary code on the host system.

Background

Xen is a bare-metal hypervisor.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
app-emulation/xen	< 4.7.1-r4	>= 4.7.1-r4	All supported architectures
app-emulation/xen-tools	< 4.7.1-r4	>= 4.7.1-r4	All supported architectures
app-emulation/xen-pvgrub	< 4.7.1-r1	>= 4.7.1-r1	All supported architectures

Description

Multiple vulnerabilities have been discovered in Xen. Please review the CVE identifiers referenced below for details.

Impact

A local attacker could possibly execute arbitrary code with the privileges of the process, could gain privileges on the host system, cause a Denial of Service condition, or obtain sensitive information.

Workaround

There is no known workaround at this time.

Resolution

All Xen users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=app-emulation/xen-4.7.1-r4"

All Xen Tools users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose
      ">=app-emulation/xen-tools-4.7.1-r4"

All Xen PvGrub users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose
      ">=app-emulation/xen-pvgrub-4.7.1-r1"
