        "text": "KVM (Kernel-based Virtual Machine) is a full virtualization solution for\nLinux on AMD64 and Intel 64 systems. The qemu-kvm-rhev packages form the\nuser-space component for running virtual machines using KVM.\n\nA flaw was found in the way QEMU handled VT100 terminal escape sequences\nwhen emulating certain character devices. A guest user with privileges to\nwrite to a character device that is emulated on the host using a virtual\nconsole back-end could use this flaw to crash the qemu-kvm process on the\nhost or, possibly, escalate their privileges on the host. (CVE-2012-3515)\n\nWhen using qemu-kvm-rhev on a Red Hat Enterprise Linux 6 host not managed\nby Red Hat Enterprise Virtualization:\n\n* This flaw did not affect the default use of KVM. Affected configurations\nwere:\n\n- When guests were started from the command line (\"/usr/libexec/qemu-kvm\")\nwithout the \"-nodefaults\" option, and also without specifying a\nserial or parallel device, or a virtio-console device, that specifically\ndoes not use a virtual console (vc) back-end. (Note that Red Hat does not\nsupport invoking \"qemu-kvm\" from the command line without \"-nodefaults\" on\nRed Hat Enterprise Linux 6.)\n\n- Guests that were managed via libvirt, such as when using Virtual Machine\nManager (virt-manager), but that have a serial or parallel device, or a\nvirtio-console device, that uses a virtual console back-end. By default,\nguests managed via libvirt will not use a virtual console back-end for such\ndevices.\n\nWhen using qemu-kvm-rhev on a Red Hat Enterprise Virtualization managed Red\nHat Enterprise Linux 6 host:\n\n* This flaw did not affect the default use of a Red Hat Enterprise\nVirtualization host: it is not possible to add a device that uses a virtual\nconsole back-end via Red Hat Enterprise Virtualization Manager.\n\nTo specify a virtual console back-end for a device and therefore be\nvulnerable to this issue, the device would have to be created another way,\nfor example, by using a VDSM hook.\n\nRed Hat would like to thank the Xen project for reporting this issue.\n\nThis update also fixes the following bugs:\n\n* Previously, the KVM modules were not loaded by the postinstall scriptlet\nof RPM scripts. This bug caused various issues and required the system to\nbe rebooted to resolve them. With this update, the modules are loaded\nproperly by the scriptlet and no unnecessary reboots are now required.\n(BZ#839897)\n\n* Previously, when a guest was started up with two serial devices, qemu-kvm\nreturned an error message and terminated the boot because IRQ 4 for the ISA\nbus was being used by both devices. This update fixes the qemu-kvm code,\nwhich allows IRQ 4 to be used by more than one device on the ISA bus, and\nthe boot now succeeds in the described scenario. (BZ#840054)\n\nAll users of qemu-kvm-rhev are advised to upgrade to these updated\npackages, which fix these issues. After installing this update, shut down\nall running virtual machines. Once all virtual machines have shut down,\nstart them again for this update to take effect.",

        "text": "KVM (Kernel-based Virtual Machine) is a full virtualization solution for\nLinux on AMD64 and Intel 64 systems. The qemu-kvm-rhev packages form the\nuser-space component for running virtual machines using KVM.\n\nA flaw was found in the way QEMU handled VT100 terminal escape sequences\nwhen emulating certain character devices. A guest user with privileges to\nwrite to a character device that is emulated on the host using a virtual\nconsole back-end could use this flaw to crash the qemu-kvm process on the\nhost or, possibly, escalate their privileges on the host. (CVE-2012-3515)\n\nWhen using qemu-kvm-rhev on a Red Hat Enterprise Linux 6 host not managed\nby Red Hat Enterprise Virtualization:\n\n* This flaw did not affect the default use of KVM. Affected configurations\nwere:\n\n- When guests were started from the command line (\"/usr/libexec/qemu-kvm\")\nwithout the \"-nodefaults\" option, and also without specifying a\nserial or parallel device, or a virtio-console device, that specifically\ndoes not use a virtual console (vc) back-end. (Note that Red Hat does not\nsupport invoking \"qemu-kvm\" from the command line without \"-nodefaults\" on\nRed Hat Enterprise Linux 6.)\n\n- Guests that were managed via libvirt, such as when using Virtual Machine\nManager (virt-manager), but that have a serial or parallel device, or a\nvirtio-console device, that uses a virtual console back-end. By default,\nguests managed via libvirt will not use a virtual console back-end for such\ndevices.\n\nWhen using qemu-kvm-rhev on a Red Hat Enterprise Virtualization managed Red\nHat Enterprise Linux 6 host:\n\n* This flaw did not affect the default use of a Red Hat Enterprise\nVirtualization host: it is not possible to add a device that uses a virtual\nconsole back-end via Red Hat Enterprise Virtualization Manager.\n\nTo specify a virtual console back-end for a device and therefore be\nvulnerable to this issue, the device would have to be created another way,\nfor example, by using a VDSM hook.\n\nRed Hat would like to thank the Xen project for reporting this issue.\n\nThis update also fixes the following bugs:\n\n* Previously, the KVM modules were not loaded by the postinstall scriptlet\nof RPM scripts. This bug caused various issues and required the system to\nbe rebooted to resolve them. With this update, the modules are loaded\nproperly by the scriptlet and no unnecessary reboots are now required.\n(BZ#839897)\n\n* Previously, when a guest was started up with two serial devices, qemu-kvm\nreturned an error message and terminated the boot because IRQ 4 for the ISA\nbus was being used by both devices. This update fixes the qemu-kvm code,\nwhich allows IRQ 4 to be used by more than one device on the ISA bus, and\nthe boot now succeeds in the described scenario. (BZ#840054)\n\nAll users of qemu-kvm-rhev are advised to upgrade to these updated\npackages, which fix these issues. After installing this update, shut down\nall running virtual machines. Once all virtual machines have shut down,\nstart them again for this update to take effect.",

The Red Hat Enterprise Virtualization\nHypervisor is a dedicated Kernel-based Virtual Machine (KVM) hypervisor.\nIt includes everything necessary to run and manage virtual machines: A\nsubset of the Red Hat Enterprise Linux operating environment and the Red\nHat Enterprise Virtualization Agent.\n\nNote: Red Hat Enterprise Virtualization Hypervisor is only available for\nthe Intel 64 and AMD64 architectures with virtualization extensions.\n\nA flaw was found in the way QEMU handled VT100 terminal escape sequences\nwhen emulating certain character devices. A guest user with privileges to\nwrite to a character device that is emulated on the host using a virtual\nconsole back-end could use this flaw to crash the qemu-kvm process on the\nhost or, possibly, escalate their privileges on the host. (CVE-2012-3515)\n\nMultiple integer overflow flaws, leading to stack-based buffer overflows,\nwere found in glibc\u0027s functions for converting a string to a numeric\nrepresentation (strtod(), strtof(), and strtold()). If an application used\nsuch a function on attacker controlled input, it could cause the\napplication to crash or, potentially, execute arbitrary code.\n(CVE-2012-3480)\n\nRed Hat would like to thank the Xen project for reporting the CVE-2012-3515\nissue.\n\nThis updated package provides updated components that include various bug\nfixes, as well as a fix for CVE-2012-3515 in the xen package; however, for\nthis component, it had no security impact on Red Hat Enterprise\nVirtualization Hypervisor itself.\n\nUsers of Red Hat Enterprise Virtualization Hypervisor are advised to\nupgrade to this updated package, which fixes these issues.",

A guest user with privileges to\nwrite to a character device that is emulated on the host using a virtual\nconsole back-end could use this flaw to crash the qemu-kvm process on the\nhost or, possibly, escalate their privileges on the host. (CVE-2012-3515)\n\nThis flaw did not affect the default use of KVM. Affected configurations\nwere:\n\n* When guests were started from the command line (\"/usr/libexec/qemu-kvm\"),\nand without specifying a serial or parallel device that specifically does\nnot use a virtual console (vc) back-end. (Note that Red Hat does not\nsupport invoking \"qemu-kvm\" from the command line on Red Hat Enterprise\nLinux 5.)\n\n* Guests that were managed via libvirt, such as when using Virtual Machine\nManager (virt-manager), but that have a serial or parallel device that uses\na virtual console back-end. By default, guests managed via libvirt will not\nuse a virtual console back-end for such devices.\n\nRed Hat would like to thank the Xen project for reporting this issue.\n\nAll KVM users should upgrade to these updated packages, which correct this\nissue.

        "text": "The rhev-hypervisor6 package provides a Red Hat Enterprise Virtualization\nHypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor\nis a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes\neverything necessary to run and manage virtual machines: A subset of the\nRed Hat Enterprise Linux operating environment and the Red Hat Enterprise\nVirtualization Agent.\n\nNote: Red Hat Enterprise Virtualization Hypervisor is only available for\nthe Intel 64 and AMD64 architectures with virtualization extensions.\n\nA flaw was found in the way QEMU handled VT100 terminal escape sequences\nwhen emulating certain character devices. A guest user with privileges to\nwrite to a character device that is emulated on the host using a virtual\nconsole back-end could use this flaw to crash the qemu-kvm process on the\nhost or, possibly, escalate their privileges on the host. (CVE-2012-3515)\n\nThis flaw did not affect the default use of Red Hat Enterprise\nVirtualization Hypervisor: it is not possible to add a device that uses a\nvirtual console back-end via Red Hat Enterprise Virtualization Manager.\n\nTo specify a virtual console back-end for a device and therefore be\nvulnerable to this issue, the device would have to be created another way,\nfor example, by using a VDSM hook. Note that at this time hooks can only be\nused on Red Hat Enterprise Linux hosts, not Red Hat Enterprise\nVirtualization Hypervisor.\n\nMultiple integer overflow flaws, leading to stack-based buffer overflows,\nwere found in glibc\u0027s functions for converting a string to a numeric\nrepresentation (strtod(), strtof(), and strtold()). If an application used\nsuch a function on attacker controlled input, it could cause the\napplication to crash or, potentially, execute arbitrary code.\n(CVE-2012-3480)\n\nRed Hat would like to thank the Xen project for reporting the CVE-2012-3515\nissue.\n\nThis updated package provides updated components that include fixes for\nvarious security issues. These issues have no security impact on Red Hat\nEnterprise Virtualization Hypervisor itself, however. The security fixes\nincluded in this update address the following CVE numbers:\n\nCVE-2012-4244 (bind issue)\n\nCVE-2012-3524 (dbus issue)\n\nCVE-2012-2313, CVE-2012-2384, CVE-2012-2390, CVE-2012-3430, and\nCVE-2012-3552 (kernel issues)\n\nCVE-2012-3445 (libvirt issue)\n\nCVE-2011-3102 and CVE-2012-2807 (libxml2 issues)\n\nCVE-2011-1202, CVE-2011-3970, CVE-2012-2825, CVE-2012-2870, CVE-2012-2871,\nand CVE-2012-2893 (libxslt issues)\n\nThis updated Red Hat Enterprise Virtualization Hypervisor package also\nfixes the following bug:\n\n* Previously, the Manager listed all installed Hypervisor ISO images as\navailable even when they did not support the VDSM compatibility version\nrequired by the selected host. The rhev-hypervisor6 package now maintains a\ntext file for each installed ISO image. The file lists the VDSM\ncompatibility versions supported by the relevant ISO image. The Manager\nuses this information to ensure that only those Hypervisor ISO images that\nare relevant to the selected host are listed. (BZ#856827)\n\nUsers of the Red Hat Enterprise Virtualization Hypervisor are advised to\nupgrade to this updated package, which fixes these issues.",

A guest user with privileges to\nwrite to a character device that is emulated on the host using a virtual\nconsole back-end could use this flaw to crash the qemu-kvm process on the\nhost or, possibly, escalate their privileges on the host. (CVE-2012-3515)\n\nThis flaw did not affect the default use of KVM. Affected configurations\nwere:\n\n* When guests were started from the command line (\"/usr/libexec/qemu-kvm\")\nwithout the \"-nodefaults\" option, and also without specifying a\nserial or parallel device, or a virtio-console device, that specifically\ndoes not use a virtual console (vc) back-end. (Note that Red Hat does not\nsupport invoking \"qemu-kvm\" from the command line without \"-nodefaults\" on\nRed Hat Enterprise Linux 6.)\n\n* Guests that were managed via libvirt, such as when using Virtual Machine\nManager (virt-manager), but that have a serial or parallel device, or a\nvirtio-console device, that uses a virtual console back-end. By default,\nguests managed via libvirt will not use a virtual console back-end\nfor such devices.\n\nRed Hat would like to thank the Xen project for reporting this issue.\n\nAll users of qemu-kvm should upgrade to these updated packages, which\nresolve this issue. After installing this update, shut down all running\nvirtual machines. Once all virtual machines have shut down, start them\nagain for this update to take effect.",

        "text": "The rhev-hypervisor6 package provides a Red Hat Enterprise Virtualization\nHypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor\nis a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes\neverything necessary to run and manage virtual machines: A subset of the\nRed Hat Enterprise Linux operating environment and the Red Hat Enterprise\nVirtualization Agent.\n\nNote: Red Hat Enterprise Virtualization Hypervisor is only available for\nthe Intel 64 and AMD64 architectures with virtualization extensions.\n\nA flaw was found in the way QEMU handled VT100 terminal escape sequences\nwhen emulating certain character devices. A guest user with privileges to\nwrite to a character device that is emulated on the host using a virtual\nconsole back-end could use this flaw to crash the qemu-kvm process on the\nhost or, possibly, escalate their privileges on the host. (CVE-2012-3515)\n\nThis flaw did not affect the default use of Red Hat Enterprise\nVirtualization Hypervisor: it is not possible to add a device that uses a\nvirtual console back-end via Red Hat Enterprise Virtualization Manager.\n\nTo specify a virtual console back-end for a device and therefore be\nvulnerable to this issue, the device would have to be created another way,\nfor example, by using a VDSM hook. Note that at this time hooks can only be\nused on Red Hat Enterprise Linux hosts, not Red Hat Enterprise\nVirtualization Hypervisor.\n\nMultiple integer overflow flaws, leading to stack-based buffer overflows,\nwere found in glibc\u0027s functions for converting a string to a numeric\nrepresentation (strtod(), strtof(), and strtold()). If an application used\nsuch a function on attacker controlled input, it could cause the\napplication to crash or, potentially, execute arbitrary code.\n(CVE-2012-3480)\n\nRed Hat would like to thank the Xen project for reporting the CVE-2012-3515\nissue.\n\nThis updated package provides updated components that include fixes for\nvarious security issues. These issues have no security impact on Red Hat\nEnterprise Virtualization Hypervisor itself, however. The security fixes\nincluded in this update address the following CVE numbers:\n\nCVE-2012-4244 (bind issue)\n\nCVE-2012-3524 (dbus issue)\n\nCVE-2012-2313, CVE-2012-2384, CVE-2012-2390, CVE-2012-3430, and\nCVE-2012-3552 (kernel issues)\n\nCVE-2012-3445 (libvirt issue)\n\nCVE-2011-3102 and CVE-2012-2807 (libxml2 issues)\n\nCVE-2011-1202, CVE-2011-3970, CVE-2012-2825, CVE-2012-2870, CVE-2012-2871,\nand CVE-2012-2893 (libxslt issues)\n\nThis updated Red Hat Enterprise Virtualization Hypervisor package also\nfixes the following bug:\n\n* Previously, the Manager listed all installed Hypervisor ISO images as\navailable even when they did not support the VDSM compatibility version\nrequired by the selected host. The rhev-hypervisor6 package now maintains a\ntext file for each installed ISO image. The file lists the VDSM\ncompatibility versions supported by the relevant ISO image. The Manager\nuses this information to ensure that only those Hypervisor ISO images that\nare relevant to the selected host are listed. (BZ#856827)\n\nUsers of the Red Hat Enterprise Virtualization Hypervisor are advised to\nupgrade to this updated package, which fixes these issues.",

A guest user with privileges to\nwrite to a character device that is emulated on the host using a virtual\nconsole back-end could use this flaw to crash the qemu-kvm process on the\nhost or, possibly, escalate their privileges on the host. (CVE-2012-3515)\n\nThis flaw did not affect the default use of KVM. Affected configurations\nwere:\n\n* When guests were started from the command line (\"/usr/libexec/qemu-kvm\"),\nand without specifying a serial or parallel device that specifically does\nnot use a virtual console (vc) back-end. (Note that Red Hat does not\nsupport invoking \"qemu-kvm\" from the command line on Red Hat Enterprise\nLinux 5.)\n\n* Guests that were managed via libvirt, such as when using Virtual Machine\nManager (virt-manager), but that have a serial or parallel device that uses\na virtual console back-end. By default, guests managed via libvirt will not\nuse a virtual console back-end for such devices.\n\nRed Hat would like to thank the Xen project for reporting this issue.\n\nAll KVM users should upgrade to these updated packages, which correct this\nissue.

        "text": "The rhev-hypervisor6 package provides a Red Hat Enterprise Virtualization\nHypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor\nis a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes\neverything necessary to run and manage virtual machines: A subset of the\nRed Hat Enterprise Linux operating environment and the Red Hat Enterprise\nVirtualization Agent.\n\nNote: Red Hat Enterprise Virtualization Hypervisor is only available for\nthe Intel 64 and AMD64 architectures with virtualization extensions.\n\nA flaw was found in the way QEMU handled VT100 terminal escape sequences\nwhen emulating certain character devices. A guest user with privileges to\nwrite to a character device that is emulated on the host using a virtual\nconsole back-end could use this flaw to crash the qemu-kvm process on the\nhost or, possibly, escalate their privileges on the host. (CVE-2012-3515)\n\nThis flaw did not affect the default use of Red Hat Enterprise\nVirtualization Hypervisor: it is not possible to add a device that uses a\nvirtual console back-end via Red Hat Enterprise Virtualization Manager.\n\nTo specify a virtual console back-end for a device and therefore be\nvulnerable to this issue, the device would have to be created another way,\nfor example, by using a VDSM hook. Note that at this time hooks can only be\nused on Red Hat Enterprise Linux hosts, not Red Hat Enterprise\nVirtualization Hypervisor.\n\nMultiple integer overflow flaws, leading to stack-based buffer overflows,\nwere found in glibc\u0027s functions for converting a string to a numeric\nrepresentation (strtod(), strtof(), and strtold()). If an application used\nsuch a function on attacker controlled input, it could cause the\napplication to crash or, potentially, execute arbitrary code.\n(CVE-2012-3480)\n\nRed Hat would like to thank the Xen project for reporting the CVE-2012-3515\nissue.\n\nThis updated package provides updated components that include fixes for\nvarious security issues. These issues have no security impact on Red Hat\nEnterprise Virtualization Hypervisor itself, however. The security fixes\nincluded in this update address the following CVE numbers:\n\nCVE-2012-4244 (bind issue)\n\nCVE-2012-3524 (dbus issue)\n\nCVE-2012-2313, CVE-2012-2384, CVE-2012-2390, CVE-2012-3430, and\nCVE-2012-3552 (kernel issues)\n\nCVE-2012-3445 (libvirt issue)\n\nCVE-2011-3102 and CVE-2012-2807 (libxml2 issues)\n\nCVE-2011-1202, CVE-2011-3970, CVE-2012-2825, CVE-2012-2870, CVE-2012-2871,\nand CVE-2012-2893 (libxslt issues)\n\nThis updated Red Hat Enterprise Virtualization Hypervisor package also\nfixes the following bug:\n\n* Previously, the Manager listed all installed Hypervisor ISO images as\navailable even when they did not support the VDSM compatibility version\nrequired by the selected host. The rhev-hypervisor6 package now maintains a\ntext file for each installed ISO image. The file lists the VDSM\ncompatibility versions supported by the relevant ISO image. The Manager\nuses this information to ensure that only those Hypervisor ISO images that\nare relevant to the selected host are listed. (BZ#856827)\n\nUsers of the Red Hat Enterprise Virtualization Hypervisor are advised to\nupgrade to this updated package, which fixes these issues.",

A guest user with privileges to\nwrite to a character device that is emulated on the host using a virtual\nconsole back-end could use this flaw to crash the qemu-kvm process on the\nhost or, possibly, escalate their privileges on the host. (CVE-2012-3515)\n\nThis flaw did not affect the default use of KVM. Affected configurations\nwere:\n\n* When guests were started from the command line (\"/usr/libexec/qemu-kvm\")\nwithout the \"-nodefaults\" option, and also without specifying a\nserial or parallel device, or a virtio-console device, that specifically\ndoes not use a virtual console (vc) back-end. (Note that Red Hat does not\nsupport invoking \"qemu-kvm\" from the command line without \"-nodefaults\" on\nRed Hat Enterprise Linux 6.)\n\n* Guests that were managed via libvirt, such as when using Virtual Machine\nManager (virt-manager), but that have a serial or parallel device, or a\nvirtio-console device, that uses a virtual console back-end. By default,\nguests managed via libvirt will not use a virtual console back-end\nfor such devices.\n\nRed Hat would like to thank the Xen project for reporting this issue.\n\nAll users of qemu-kvm should upgrade to these updated packages, which\nresolve this issue. After installing this update, shut down all running\nvirtual machines. Once all virtual machines have shut down, start them\nagain for this update to take effect.",

A guest user with privileges to\nwrite to a character device that is emulated on the host using a virtual\nconsole back-end could use this flaw to crash the qemu-kvm process on the\nhost or, possibly, escalate their privileges on the host. (CVE-2012-3515)\n\nMultiple integer overflow flaws, leading to stack-based buffer overflows,\nwere found in glibc\u0027s functions for converting a string to a numeric\nrepresentation (strtod(), strtof(), and strtold()). If an application used\nsuch a function on attacker controlled input, it could cause the\napplication to crash or, potentially, execute arbitrary code.\n(CVE-2012-3480)\n\nRed Hat would like to thank the Xen project for reporting the CVE-2012-3515\nissue.\n\nThis updated package provides updated components that include various bug\nfixes, as well as a fix for CVE-2012-3515 in the xen package; however, for\nthis component, it had no security impact on Red Hat Enterprise\nVirtualization Hypervisor itself.\n\nUsers of Red Hat Enterprise Virtualization Hypervisor are advised to\nupgrade to this updated package, which fixes these issues.",

A guest user with privileges to\nwrite to a character device that is emulated on the host using a virtual\nconsole back-end could use this flaw to crash the qemu-kvm process on the\nhost or, possibly, escalate their privileges on the host. (CVE-2012-3515)\n\nMultiple integer overflow flaws, leading to stack-based buffer overflows,\nwere found in glibc\u0027s functions for converting a string to a numeric\nrepresentation (strtod(), strtof(), and strtold()). If an application used\nsuch a function on attacker controlled input, it could cause the\napplication to crash or, potentially, execute arbitrary code.\n(CVE-2012-3480)\n\nRed Hat would like to thank the Xen project for reporting the CVE-2012-3515\nissue.\n\nThis updated package provides updated components that include various bug\nfixes, as well as a fix for CVE-2012-3515 in the xen package; however, for\nthis component, it had no security impact on Red Hat Enterprise\nVirtualization Hypervisor itself.\n\nUsers of Red Hat Enterprise Virtualization Hypervisor are advised to\nupgrade to this updated package, which fixes these issues.",

        "text": "KVM (Kernel-based Virtual Machine) is a full virtualization solution for\nLinux on AMD64 and Intel 64 systems. The qemu-kvm-rhev packages form the\nuser-space component for running virtual machines using KVM.\n\nA flaw was found in the way QEMU handled VT100 terminal escape sequences\nwhen emulating certain character devices. A guest user with privileges to\nwrite to a character device that is emulated on the host using a virtual\nconsole back-end could use this flaw to crash the qemu-kvm process on the\nhost or, possibly, escalate their privileges on the host. (CVE-2012-3515)\n\nWhen using qemu-kvm-rhev on a Red Hat Enterprise Linux 6 host not managed\nby Red Hat Enterprise Virtualization:\n\n* This flaw did not affect the default use of KVM. Affected configurations\nwere:\n\n- When guests were started from the command line (\"/usr/libexec/qemu-kvm\")\nwithout the \"-nodefaults\" option, and also without specifying a\nserial or parallel device, or a virtio-console device, that specifically\ndoes not use a virtual console (vc) back-end. (Note that Red Hat does not\nsupport invoking \"qemu-kvm\" from the command line without \"-nodefaults\" on\nRed Hat Enterprise Linux 6.)\n\n- Guests that were managed via libvirt, such as when using Virtual Machine\nManager (virt-manager), but that have a serial or parallel device, or a\nvirtio-console device, that uses a virtual console back-end. By default,\nguests managed via libvirt will not use a virtual console back-end for such\ndevices.\n\nWhen using qemu-kvm-rhev on a Red Hat Enterprise Virtualization managed Red\nHat Enterprise Linux 6 host:\n\n* This flaw did not affect the default use of a Red Hat Enterprise\nVirtualization host: it is not possible to add a device that uses a virtual\nconsole back-end via Red Hat Enterprise Virtualization Manager.\n\nTo specify a virtual console back-end for a device and therefore be\nvulnerable to this issue, the device would have to be created another way,\nfor example, by using a VDSM hook.\n\nRed Hat would like to thank the Xen project for reporting this issue.\n\nThis update also fixes the following bugs:\n\n* Previously, the KVM modules were not loaded by the postinstall scriptlet\nof RPM scripts. This bug caused various issues and required the system to\nbe rebooted to resolve them. With this update, the modules are loaded\nproperly by the scriptlet and no unnecessary reboots are now required.\n(BZ#839897)\n\n* Previously, when a guest was started up with two serial devices, qemu-kvm\nreturned an error message and terminated the boot because IRQ 4 for the ISA\nbus was being used by both devices. This update fixes the qemu-kvm code,\nwhich allows IRQ 4 to be used by more than one device on the ISA bus, and\nthe boot now succeeds in the described scenario. (BZ#840054)\n\nAll users of qemu-kvm-rhev are advised to upgrade to these updated\npackages, which fix these issues. After installing this update, shut down\nall running virtual machines. Once all virtual machines have shut down,\nstart them again for this update to take effect.",

A guest user with privileges to\nwrite to a character device that is emulated on the host using a virtual\nconsole back-end could use this flaw to crash the qemu-kvm process on the\nhost or, possibly, escalate their privileges on the host. (CVE-2012-3515)\n\nThis flaw did not affect the default use of KVM. Affected configurations\nwere:\n\n* When guests were started from the command line (\"/usr/libexec/qemu-kvm\")\nwithout the \"-nodefaults\" option, and also without specifying a\nserial or parallel device, or a virtio-console device, that specifically\ndoes not use a virtual console (vc) back-end. (Note that Red Hat does not\nsupport invoking \"qemu-kvm\" from the command line without \"-nodefaults\" on\nRed Hat Enterprise Linux 6.)\n\n* Guests that were managed via libvirt, such as when using Virtual Machine\nManager (virt-manager), but that have a serial or parallel device, or a\nvirtio-console device, that uses a virtual console back-end. By default,\nguests managed via libvirt will not use a virtual console back-end\nfor such devices.\n\nRed Hat would like to thank the Xen project for reporting this issue.\n\nAll users of qemu-kvm should upgrade to these updated packages, which\nresolve this issue.

KVM is a Linux kernel module built\nfor the standard Red Hat Enterprise Linux kernel.\n\nA flaw was found in the way QEMU handled VT100 terminal escape sequences\nwhen emulating certain character devices. A guest user with privileges to\nwrite to a character device that is emulated on the host using a virtual\nconsole back-end could use this flaw to crash the qemu-kvm process on the\nhost or, possibly, escalate their privileges on the host. (CVE-2012-3515)\n\nThis flaw did not affect the default use of KVM. Affected configurations\nwere:\n\n* When guests were started from the command line (\"/usr/libexec/qemu-kvm\"),\nand without specifying a serial or parallel device that specifically does\nnot use a virtual console (vc) back-end. (Note that Red Hat does not\nsupport invoking \"qemu-kvm\" from the command line on Red Hat Enterprise\nLinux 5.)\n\n* Guests that were managed via libvirt, such as when using Virtual Machine\nManager (virt-manager), but that have a serial or parallel device that uses\na virtual console back-end. By default, guests managed via libvirt will not\nuse a virtual console back-end for such devices.\n\nRed Hat would like to thank the Xen project for reporting this issue.\n\nAll KVM users should upgrade to these updated packages, which correct this\nissue. Note: The procedure in the Solution section must be performed before\nthis update will take effect.",
