Detail

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.

Description

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

Impact

A local attacker could potentially execute arbitrary code with privileges of Xen (QEMU) process on the host, 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-r5"

All Xen Tools users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot -v ">=app-emulation/xen-tools-4.7.1-r6"
