Command injection

QEMU, as used in Xen 3.3.x through 4.5.x, does not properly restrict access to PCI command registers, which might allow local HVM guest users to cause a denial of service non-maskable interrupt and host crash by disabling the 1 memory or 2 I/O decoding for a PCI Express device and then accessing...

CVE-2015-2756

CVE-2015-2756 affects QEMU as used in Xen 3.3.x–4.5.x and describes that local HVM guests can disable memory or I/O decoding for a PCI Express device, causing a denial of service via an Unsupported Request (UR) response and potential host crash. The Debian DLA-479-1 advisory notes Xen 4.1.x serie...

CVE-2015-2752

The CVE-2015-2752 issue affects Xen 3.2.x–4.5.x (PCI passthrough) where the XEN_DOMCTL_memory_mapping hypercall is not preemptible, enabling local x86 HVM users to cause host CPU exhaustion (DoS) via crafted device-model requests (qemu-dm). Public advisories in Debian (DLA-479-1) and Mageia (MGAS...

Long latency MMIO mapping operations are not preemptible

ISSUE DESCRIPTION The XENDOMCTLmemorymapping hypercall allows long running operations without implementing preemption. This hypercall is used by the device model as part of the emulation associated with configuration of PCI devices passed through to HVM guests and is therefore indirectly exposed ...

Unmediated PCI command register access in qemu

ISSUE DESCRIPTION HVM guests are currently permitted to modify the memory and I/O decode bits in the PCI command register of devices passed through to them. Unless the device is an SR-IOV virtual function, after disabling one or both of these bits subsequent accesses to the MMIO or I/O port range...

Scientific Linux Security Update : libvirt on SL7.x x86_64 (20150305)

It was found that QEMU's qemuDomainMigratePerform and qemuDomainMigrateFinish2 functions did not correctly perform a domain unlock on a failed ACL check. A remote attacker able to establish a connection to libvirtd could use this flaw to lock a domain of a more privileged user, causing a denial o...
