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 ------------------------------------------------------------------- 1 app-emulation/xen < 4.7.1-r5 >= 4.7.1-r5 2 app-emulation/xen-tools < 4.7.1-r6 >= 4.7.1-r6 ------------------------------------------------------------------- 2 affected packages
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"
