Heap-based buffer overflow in the process_tx_desc function in the e1000 emulation (hw/e1000.c) in qemu-kvm 0.12, and possibly other versions, allows guest OS users to cause a denial of service (QEMU crash) and possibly execute arbitrary code via crafted legacy mode packets.

The remote OracleVM system is missing necessary patches to address critical security updates : please see Oracle VM Security Advisory OVMSA-2015-0068 for details.

An updated rhev-hypervisor5 package that fixes several security issues and various bugs is now available.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The rhev-hypervisor5 package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes everything necessary to run and manage virtual machines: A subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent.

Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions.

A heap overflow flaw was found in the way QEMU-KVM emulated the e1000 network interface card. A privileged guest user in a virtual machine whose network interface is configured to use the e1000 emulated driver could use this flaw to crash the host or, possibly, escalate their privileges on the host. (CVE-2012-0029)

A divide-by-zero flaw was found in the Linux kernel's igmp_heard_query() function. An attacker able to send certain IGMP (Internet Group Management Protocol) packets to a target system could use this flaw to cause a denial of service. (CVE-2012-0207)

A double free flaw was discovered in the policy checking code in OpenSSL. A remote attacker could use this flaw to crash an application that uses OpenSSL by providing an X.509 certificate that has specially crafted policy extension data. (CVE-2011-4109)

An information leak flaw was found in the SSL 3.0 protocol implementation in OpenSSL. Incorrect initialization of SSL record padding bytes could cause an SSL client or server to send a limited amount of possibly sensitive data to its SSL peer via the encrypted connection. (CVE-2011-4576)

It was discovered that OpenSSL did not limit the number of TLS/SSL handshake restarts required to support Server Gated Cryptography. A remote attacker could use this flaw to make a TLS/SSL server using OpenSSL consume an excessive amount of CPU by continuously restarting the handshake. (CVE-2011-4619)

Red Hat would like to thank Nicolae Mogoreanu for reporting CVE-2012-0029, and Simon McVittie for reporting CVE-2012-0207.

    This updated package provides updated components that include fixes for     various security issues. These issues have no security impact on Red Hat     Enterprise Virtualization Hypervisor itself, however. The security fixes     included in this update address the following CVE numbers:

    CVE-2009-5029 and CVE-2011-4609 (glibc issues)

    CVE-2012-0056 (kernel issue)

    CVE-2011-4108 and CVE-2012-0050 (openssl issues)

    This update also fixes the following bugs:

    * Previously, it was possible to begin a Hypervisor installation without     any valid disks to install to.

    Now, if no valid disks are found for Hypervisor installation, a message is     displayed informing the user that there are no valid disks for     installation. (BZ#781471)

    * Previously, the user interface for the Hypervisor did not indicate     whether the system was registered with Red Hat Network (RHN) Classic or RHN     Satellite. As a result, customers could not easily determine the     registration status of their Hypervisor installations.

    The TUI has been updated to display the registration status of the     Hypervisor. (BZ#788223)

    * Previously, autoinstall would fail if the firstboot or reinstall options     were passed but local_boot or upgrade were not passed. Now, neither the     local_boot or upgrade parameters are required for autoinstall. (BZ#788225)

    Users of the Red Hat Enterprise Virtualization Hypervisor are advised to     upgrade to this updated package, which fixes these issues.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

From Red Hat Security Advisory 2012:0050 :

Updated qemu-kvm packages that fix one security issue, one bug, and add one enhancement are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. qemu-kvm is the user-space component for running virtual machines using KVM.

A heap overflow flaw was found in the way QEMU-KVM emulated the e1000 network interface card. A privileged guest user in a virtual machine whose network interface is configured to use the e1000 emulated driver could use this flaw to crash the host or, possibly, escalate their privileges on the host. (CVE-2012-0029)

Red Hat would like to thank Nicolae Mogoreanu for reporting this issue.

This update also fixes the following bug :

* qemu-kvm has a 'scsi' option, to be used, for example, with the '-device' option: '-device virtio-blk-pci,drive=[drive name],scsi=off'. Previously, however, it only masked the feature bit, and did not reject SCSI commands if a malicious guest ignored the feature bit and issued a request. This update corrects this issue. The 'scsi=off' option can be used to mitigate the virtualization aspect of CVE-2011-4127 before the RHSA-2011:1849 kernel update is installed on the host.

This mitigation is only required if you do not have the RHSA-2011:1849 kernel update installed on the host and you are using raw format virtio disks backed by a partition or LVM volume.

If you run guests by invoking /usr/libexec/qemu-kvm directly, use the '-global virtio-blk-pci.scsi=off' option to apply the mitigation. If you are using libvirt, as recommended by Red Hat, and have the RHBA-2012:0013 libvirt update installed, no manual action is required:
guests will automatically use 'scsi=off'. (BZ#767721)

Note: After installing the RHSA-2011:1849 kernel update, SCSI requests issued by guests via the SG_IO IOCTL will not be passed to the underlying block device when using raw format virtio disks backed by a partition or LVM volume, even if 'scsi=on' is used.

As well, this update adds the following enhancement :

* Prior to this update, qemu-kvm was not built with RELRO or PIE support. qemu-kvm is now built with full RELRO and PIE support as a security enhancement. (BZ#767906)

All users of qemu-kvm should upgrade to these updated packages, which correct these issues and add this enhancement. 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.

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2012:0051 advisory.

  - kernel: kvm: pit timer with no irqchip crashes the system (CVE-2011-4622)

  - qemu: e1000: process_tx_desc legacy mode packets heap overflow (CVE-2012-0029)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2012:0050 advisory.

  - qemu: e1000: process_tx_desc legacy mode packets heap overflow (CVE-2012-0029)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote host is affected by the vulnerability described in GLSA-201210-04 (qemu-kvm: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in qemu-kvm. Please review       the CVE identifiers referenced below for details.
  Impact :

    These vulnerabilities allow a remote attacker to cause a Denial of       Service condition on the host server or qemu process, might allow for       arbitrary code execution or a symlink attack when qemu-kvm is in snapshot       mode.
  Workaround :

    There is no known workaround at this time.

The xen packages contain administration tools and the xend service for managing the kernel-xen kernel for virtualization on Scientific Linux.

A heap overflow flaw was found in the way QEMU emulated the e1000 network interface card. A privileged guest user in a virtual machine whose network interface is configured to use the e1000 emulated driver could use this flaw to crash QEMU or, possibly, escalate their privileges on the host. (CVE-2012-0029)

This update also fixes the following bugs :

  - Adding support for jumbo frames introduced incorrect     network device expansion when a bridge is created. The     expansion worked correctly with the default     configuration, but could have caused network setup     failures when a user-defined network script was used.
    This update changes the expansion so network setup will     not fail, even when a user-defined network script is     used.

  - A bug was found in xenconsoled, the Xen hypervisor     console daemon. If timestamp logging for this daemon was     enabled (using both the     XENCONSOLED_TIMESTAMP_HYPERVISOR_LOG and     XENCONSOLED_TIMESTAMP_GUEST_LOG options in     '/etc/sysconfig/xend'), xenconsoled could crash if the     guest emitted a lot of information to its serial console     in a short period of time. Eventually, the guest would     freeze after the console buffer was filled due to the     crashed xenconsoled. Timestamp logging is disabled by     default.

All xen users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. KVM is a Linux kernel module built for the standard Scientific Linux kernel.

A heap overflow flaw was found in the way QEMU-KVM emulated the e1000 network interface card. A privileged guest user in a virtual machine whose network interface is configured to use the e1000 emulated driver could use this flaw to crash the host or, possibly, escalate their privileges on the host. (CVE-2012-0029)

A flaw was found in the way the KVM subsystem of a Linux kernel handled PIT (Programmable Interval Timer) IRQs (interrupt requests) when there was no virtual interrupt controller set up. A malicious user in the kvm group on the host could force this situation to occur, resulting in the host crashing. (CVE-2011-4622)

All KVM users should upgrade to these updated packages, which contain backported patches to correct these issues. Note: The procedure in the Solution section must be performed before this update will take effect.

All users of qemu-kvm should upgrade to these updated packages, which correct these issues and add this enhancement. 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.

Nicolae Mogoreanu discovered that QEMU did not properly verify legacy mode packets in the e1000 network driver. A remote attacker could exploit this to cause a denial of service or possibly execute code with the privileges of the user invoking the program.

When using QEMU with libvirt or virtualization management software based on libvirt such as Eucalyptus and OpenStack, QEMU guests are individually isolated by an AppArmor profile by default in Ubuntu.
