Synopsis ========
Multiple vulnerabilities have been found in Xen, the worst of which could allow for privilege escalation.
Background ==========
Xen is a bare-metal hypervisor.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-emulation/xen < 4.7.2-r1 >= 4.7.2-r1 2 app-emulation/xen-tools < 4.7.2 >= 4.7.2 3 app-emulation/xen-pvgrub < 4.7.2 >= 4.7.2 ------------------------------------------------------------------- 3 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, or cause a Denial of Service condition.
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-4.7.2-r1:0"
All Xen Tools users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot -v ">=app-emulation/xen-tools-4.7.2:0"
All Xen pvgrub users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot -v ">=app-emulation/xen-pvgrub-4.7.2:0"
