Detail

Qemu before 2.0 block driver for Hyper-V VHDX Images is vulnerable to infinite loops and other potential issues when calculating BAT entries, due to missing bounds checks for block_size and logical_sector_size variables. These are used to derive other fields like 'sectors_per_block' etc. A user able to alter the Qemu disk image could ise this flaw to crash the Qemu instance resulting in DoS.

Title: DEPRECATED: ELSA-2014-0420 -- qemu-kvm security update (Moderate)
Description: KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm package provides the user-space component for running virtual machines using KVM. Multiple integer overflow, input validation, logic error, and buffer overflow flaws were discovered in various QEMU block drivers. An attacker able to modify a disk image file loaded by a guest could use these flaws to crash the guest, or corrupt QEMU process memory on the host, potentially resulting in arbitrary code execution on the host with the privileges of the QEMU process. (CVE-2014-0143, CVE-2014-0144, CVE-2014-0145, CVE-2014-0147) A buffer overflow flaw was found in the way the virtio_net_handle_mac() function of QEMU processed guest requests to update the table of MAC addresses. A privileged guest user could use this flaw to corrupt QEMU process memory on the host, potentially resulting in arbitrary code execution on the host with the privileges of the QEMU process. (CVE-2014-0150) A divide-by-zero flaw was found in the seek_to_sector() function of the parallels block driver in QEMU. An attacker able to modify a disk image file loaded by a guest could use this flaw to crash the guest. (CVE-2014-0142) A NULL pointer dereference flaw was found in the QCOW2 block driver in QEMU. An attacker able to modify a disk image file loaded by a guest could use this flaw to crash the guest. (CVE-2014-0146) It was found that the block driver for Hyper-V VHDX images did not correctly calculate BAT (Block Allocation Table) entries due to a missing bounds check. An attacker able to modify a disk image file loaded by a guest could use this flaw to crash the guest. (CVE-2014-0148) The CVE-2014-0143 issues were discovered by Kevin Wolf and Stefan Hajnoczi of Red Hat, the CVE-2014-0144 issues were discovered by Fam Zheng, Jeff Cody, Kevin Wolf, and Stefan Hajnoczi of Red Hat, the CVE-2014-0145 issues were discovered by Stefan Hajnoczi of Red Hat, the CVE-2014-0150 issue was discovered by Michael S. Tsirkin of Red Hat, the CVE-2014-0142, CVE-2014-0146, and CVE-2014-0147 issues were discovered by Kevin Wolf of Red Hat, and the CVE-2014-0148 issue was discovered by Jeff Cody of Red Hat. All qemu-kvm users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, shut down all running virtual machines. Once all virtual machines have shut down, start them again for this update to take effect.
