Description

Multiple denial of service vulnerabilities have been discovered in the Xen Hypervisor. One of the issue (CVE-2012-5513) could even lead to privilege escalation from guest to host.

Some of the recently published Xen Security Advisories (XSA 25 and 28) are not fixed by this update and should be fixed in a future release.

CVE-2011-3131 (XSA 5): DoS using I/OMMU faults from PCI-passthrough guest A VM that controls a PCI[E] device directly can cause it to issue DMA requests to invalid addresses. Although these requests are denied by the I/OMMU, the hypervisor needs to handle the interrupt and clear the error from the I/OMMU, and this can be used to live-lock a CPU and potentially hang the host.

Description truncated. Please see the references for more information.
