openSUSE Security Update : kvm (openSUSE-SU-2011:0510-1)

By causing a hot-unplug of the pci-isa bridge from within guests the qemu process could access already freed memory. A privileged user inside the guest could exploit that to crash the guest instance or potentially execute arbitrary code on the host CVE-2011-1751. The virtio-blk driver did not...

openSUSE Security Update : kvm (openSUSE-SU-2011:0803-1)

A privileged guest user could cause a buffer overflow in the virtio subsystem of the host, therefore crashing the guest or potentially execute arbitrary code on the host CVE-2011-2212, CVE-2011-2512. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text and package checks in...

Oracle Linux 6 : qemu-kvm (ELSA-2014-0743)

The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2014-0743 advisory. 0.12.1.2-2.415.el65.10 - kvm-virtio-out-of-bounds-buffer-write-on-invalid-state-l.patch bz1095692 -...

qemu: virtio: out-of-bounds buffer write on invalid state load

The virtioload function in virtio/virtio.c in QEMU 1.x before 1.7.2 allows remote attackers to execute arbitrary code via a crafted savevm image, which triggers an out-of-bounds write...

qemu: virtio: insufficient validation of num_sg when mapping

An user able to alter the savevm data either on the disk or over the wire during migration could use this flaw to to corrupt QEMU process memory on the destination host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process...
