Synopsis ========
Multiple vulnerabilities have been found in Xen, the worst of which allows gaining of privileges on the host system.
Background ==========
Xen is a bare-metal hypervisor.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-emulation/xen < 4.6.3-r3 >= 4.6.3-r3 2 app-emulation/xen-tools < 4.6.3-r2 >= 4.6.3-r2 ------------------------------------------------------------------- 2 affected packages
Description ===========
Multiple vulnerabilities have been discovered in Xen. Please review the CVE identifiers referenced below for details.
Impact ======
A malicious guest administrator could escalate their privileges on the host system or cause a Denial of Service. Additionally, a malicious unprivileged guest user may be able to obtain or corrupt sensitive information (including cryptographic material) in other programs in the same guest.
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-4.6.3-r3"
All Xen tools users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot -v ">=app-emulation/xen-tools-4.6.3-r2
