Xen is a bare-metal hypervisor.
Multiple vulnerabilities have been discovered in Xen. Please review the CVE identifiers referenced below for details.
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.
There is no known workaround at this time.
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 --verbose ">=app-emulation/xen-tools-4.6.3-r2
