(CVE-2012-0029)\n\nRed Hat would like to thank Nicolae Mogoreanu for reporting this issue.\n\nThis update also fixes the following bug :\n\n* 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.\n\nThis 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.\n\nIf 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:\nguests will automatically use 'scsi=off'. (BZ#767721)\n\nNote: 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.\n\nAs well, this update adds the following enhancement :\n\n* 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)\n\nAll users of qemu-kvm should upgrade to these updated packages, which correct these issues and add this enhancement.

A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.\n\nKVM (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.\n\nA 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)\n\nRed Hat would like to thank Nicolae Mogoreanu for reporting this issue.\n\nThis update also fixes the following bug :\n\n* 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.\n\nThis 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.\n\nIf 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:\nguests will automatically use 'scsi=off'. (BZ#767721)\n\nNote: 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.\n\nAs well, this update adds the following enhancement :\n\n* 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)\n\nAll users of qemu-kvm should upgrade to these updated packages, which correct these issues and add this enhancement.

"SUSE-SU-2013:0786-1", "type": "suse", "title": "Security update for Linux kernel (important)", "description": "The SUSE Linux Enterprise Server 11 SP2 Realtime kernel has\n been updated to 3.0.74 fixing various bugs and security\n issues.\n\n This update brings some features:\n\n * Updated HD-audio drivers for Nvidia/AMD HDMI and\n Haswell audio (FATE#314311 FATE#313695)\n * Lustre enablement patches were added (FATE#314679).\n * SGI UV (Ultraviolet) platform support. (FATE#306952)\n\n Security issues fixed in this update:\n\n * CVE-2013-0349: The hidp_setup_hid function in\n net/bluetooth/hidp/core.c in the Linux kernel did not\n properly copy a certain name field, which allowed local\n users to obtain sensitive information from kernel memory by\n setting a long name and making an HIDPCONNADD ioctl call.\n * CVE-2012-2137: Buffer overflow in virt/kvm/irq_comm.c\n in the KVM subsystem in the Linux kernel allowed local\n users to cause a denial of service (crash) and to possibly\n execute arbitrary code via vectors related to Message\n Signaled Interrupts (MSI), irq routing entries, and an\n incorrect check by the setup_routing_entry function before\n invoking the kvm_set_irq function.\n * CVE-2012-6549: The isofs_export_encode_fh function in\n fs/isofs/export.c in the Linux kernel did not initialize a\n certain structure member, which allowed local users to\n obtain sensitive information from kernel heap memory via a\n crafted application.\n * CVE-2012-6548: The udf_encode_fh function in\n fs/udf/namei.c in the Linux kernel did not initialize a\n certain structure member, which allowed local users to\n obtain sensitive information from kernel heap memory via a\n crafted application.\n * CVE-2013-0160: Timing side channel on attacks were\n possible on /dev/ptmx that could allow local attackers to\n predict keypresses like e.g. passwords. This has been fixed\n by not updating accessed/modified time on the pty devices.\n Note that this might break pty idle detection, so it might\n get reverted again.\n * CVE-2013-0216: The Xen netback functionality in the\n Linux kernel allowed guest OS users to cause a denial of\n service (loop) by triggering ring pointer corruption.\n * CVE-2013-0231: The pciback_enable_msi function in the\n PCI backend driver\n (drivers/xen/pciback/conf_space_capability_msi.c) in Xen\n for the Linux allowed guest OS users with PCI device access\n to cause a denial of service via a large number of kernel\n log messages.\n * CVE-2013-0311: The translate_desc function in\n drivers/vhost/vhost.c in the Linux kernel did not properly\n handle cross-region descriptors, which allowed guest OS\n users to obtain host OS privileges by leveraging KVM guest\n OS privileges.\n * CVE-2013-0913: Integer overflow in\n drivers/gpu/drm/i915/i915_gem_execbuffer.c in the i915\n driver in the Direct Rendering Manager (DRM) subsystem in\n the Linux kernel allowed local users to cause a denial of\n service (heap-based buffer overflow) or possibly have\n unspecified other impact via a crafted application that\n triggers many relocation copies, and potentially leads to a\n race condition.\n * CVE-2013-0914: The flush_signal_handlers function in\n kernel/signal.c in the Linux kernel preserved the value of\n the sa_restorer field across an exec operation, which makes\n it easier for local users to bypass the ASLR protection\n mechanism via a crafted application containing a sigaction\n system call.\n * CVE-2013-1767: Use-after-free vulnerability in the\n shmem_remount_fs function in mm/shmem.c in the Linux kernel\n allowed local users to gain privileges or to cause a denial\n of service (system crash) by remounting a tmpfs filesystem\n without specifying a required mpol (aka mempolicy) mount\n option.\n * CVE-2013-1772: The log_prefix function in\n kernel/printk.c in the Linux kernel 3.x did not properly\n remove a prefix string from a syslog header, which allowed\n local users to cause a denial of service (buffer overflow\n and system crash) by leveraging /dev/kmsg write access and\n triggering a call_console_drivers function call.\n * CVE-2013-1774: The chase_port function in\n drivers/usb/serial/io_ti.c in the Linux kernel allowed\n local users to cause a denial of service (NULL pointer\n dereference and system crash) via an attempted /dev/ttyUSB\n read or write operation on a disconnected Edgeport USB\n serial converter.\n * CVE-2013-1792: Race condition in the\n install_user_keyrings function in\n security/keys/process_keys.c in the Linux kernel allowed\n local users to cause a denial of service (NULL pointer\n dereference and system crash) via crafted keyctl system\n calls that trigger keyring operations in simultaneous\n threads.\n * CVE-2013-1796: The kvm_set_msr_common function in\n arch/x86/kvm/x86.c in the Linux kernel did not ensure a\n required time_page alignment during an MSR_KVM_SYSTEM_TIME\n operation, which allowed guest OS users to cause a denial\n of service (buffer overflow and host OS memory corruption)\n or possibly have unspecified other impact via a crafted\n application.\n * CVE-2013-1797: Use-after-free vulnerability in\n arch/x86/kvm/x86.c in the Linux kernel allowed guest OS\n users to cause a denial of service (host OS memory\n corruption) or possibly have unspecified other impact via a\n crafted application that triggers use of a guest physical\n address (GPA) in (1) movable or (2) removable memory during\n an MSR_KVM_SYSTEM_TIME kvm_set_msr_common operation.\n * CVE-2013-1798: The ioapic_read_indirect function in\n virt/kvm/ioapic.c in the Linux kernel did not properly\n handle a certain combination of invalid IOAPIC_REG_SELECT\n and IOAPIC_REG_WINDOW operations, which allows guest OS\n users to obtain sensitive information from host OS memory\n or cause a denial of service (host OS OOPS) via a crafted\n application.\n * CVE-2013-1848: fs/ext3/super.c in the Linux kernel\n used incorrect arguments to functions in certain\n circumstances related to printk input, which allowed local\n users to conduct format-string attacks and possibly gain\n privileges via a crafted application.\n * CVE-2013-1860: Heap-based buffer overflow in the\n wdm_in_callback function in drivers/usb/class/cdc-wdm.c in\n the Linux kernel allowed physically proximate attackers to\n cause a denial of service (system crash) or to possibly\n execute arbitrary code via a crafted cdc-wdm USB device.\n * CVE-2013-2634: net/dcb/dcbnl.c in the Linux kernel\n did not initialize certain structures, which allowed local\n users to obtain sensitive information from kernel stack\n memory via a crafted application.\n * CVE-2013-2635: The rtnl_fill_ifinfo function in\n net/core/rtnetlink.c in the Linux kernel did not initialize\n a certain structure member, which allowed local users to\n obtain sensitive information from kernel stack memory via a\n crafted application.\n * CVE-2013-0268: The msr_open function in\n arch/x86/kernel/msr.c in the Linux kernel allowed local\n users to bypass intended capability restrictions by\n executing a crafted application as root, as demonstrated by\n msr32.c.\n\n Bugs fixed in this update:\n\n BTRFS:\n\n * btrfs: do not try to notify udev

(CVE-2012-0029)\n\nRed Hat would like to thank Nicolae Mogoreanu for reporting this issue.\n\nThis update also fixes the following bug:\n\n* qemu-kvm has a \"scsi\" option, to be used, for example, with the\n\"-device\" option: \"-device virtio-blk-pci,drive=[drive name],scsi=off\".\nPreviously, however, it only masked the feature bit, and did not reject\nSCSI commands if a malicious guest ignored the feature bit and issued a\nrequest. This update corrects this issue. The \"scsi=off\" option can be\nused to mitigate the virtualization aspect of CVE-2011-4127 before the\nRHSA-2011:1849 kernel update is installed on the host.\n\nThis mitigation is only required if you do not have the RHSA-2011:1849\nkernel update installed on the host and you are using raw format virtio\ndisks backed by a partition or LVM volume.\n\nIf you run guests by invoking /usr/libexec/qemu-kvm directly, use the\n\"-global virtio-blk-pci.scsi=off\" option to apply the mitigation. If you\nare using libvirt, as recommended by Red Hat, and have the RHBA-2012:0013\nlibvirt update installed, no manual action is required: guests will\nautomatically use \"scsi=off\". (BZ#767721)\n\nNote: After installing the RHSA-2011:1849 kernel update, SCSI requests\nissued by guests via the SG_IO IOCTL will not be passed to the underlying\nblock device when using raw format virtio disks backed by a partition or\nLVM volume, even if \"scsi=on\" is used.\n\nAs well, this update adds the following enhancement:\n\n* Prior to this update, qemu-kvm was not built with RELRO or PIE support.\nqemu-kvm is now built with full RELRO and PIE support as a security\nenhancement. (BZ#767906)\n\nAll users of qemu-kvm should upgrade to these updated packages, which\ncorrect these issues and add this enhancement. After installing this\nupdate, shut down all running virtual machines. Once all virtual machines\nhave shut down, start them again for this update to take effect.\n\n\n**Merged security bulletin from advisories:**\nhttp://lists.centos.org/pipermail/centos-announce/2012-January/018383.html\n\n**Affected packages:**\nqemu-img\nqemu-kvm\nqemu-kvm-tools\n\n**Upstream details at:**\nhttps://rhn.redhat.com/errata/RHSA-2012-0050.html", "published": "2012-01-23T22:15:05", "cvss": {"score": 7.4, "vector": "AV:ADJACENT_NETWORK/AC:MEDIUM/Au:SINGLE_INSTANCE/C:COMPLETE/I:COMPLETE/A:COMPLETE/"}, "href": "http://lists.centos.org/pipermail/centos-announce/2012-January/018383.html", "cvelist": ["CVE-2012-0029", "CVE-2011-4127"], "lastseen": "2017-10-03T18:25:34"}, {"id": "CESA-2012:0350", "type": "centos", "title": "kernel, perf, python security update", "description": "**CentOS Errata and Security Advisory** CESA-2012:0350\n\n\nThe kernel packages contain the Linux kernel, the core of any Linux\noperating system.\n\nThis update fixes the following security issues:\n\n* A buffer overflow flaw was found in the way the Linux kernel's XFS file\nsystem implementation handled links with overly long path names.

found in the way the Linux kernel's XFS file system implementation handled links with overly long path names. A local, unprivileged user could use this flaw to cause a denial of service or escalate their privileges by mounting a specially-crafted disk. ([CVE-2011-4077 __](<https://access.redhat.com/security/cve/CVE-2011-4077>), Moderate)\n\nFlaws in ghash_update() and ghash_final() could allow a local, unprivileged user to cause a denial of service. ([CVE-2011-4081 __](<https://access.redhat.com/security/cve/CVE-2011-4081>), Moderate)\n\nA flaw was found in the Linux kernel's Journaling Block Device (JBD). A local, unprivileged user could use this flaw to crash the system by mounting a specially-crafted ext3 or ext4 disk. ([CVE-2011-4132 __](<https://access.redhat.com/security/cve/CVE-2011-4132>), Moderate)\n\nIt was found that the kvm_vm_ioctl_assign_device() function in the KVM (Kernel-based Virtual Machine) subsystem of a Linux kernel did not check if the user requesting device assignment was privileged or not. A local, unprivileged user on the host could assign unused PCI devices, or even devices that were in use and whose resources were not properly claimed by the respective drivers, which could result in the host crashing. ([CVE-2011-4347 __](<https://access.redhat.com/security/cve/CVE-2011-4347>), Moderate)\n\nTwo flaws were found in the way the Linux kernel's __sys_sendmsg() function, when invoked via the sendmmsg() system call, accessed user-space memory. A local, unprivileged user could use these flaws to cause a denial of service. ([CVE-2011-4594 __](<https://access.redhat.com/security/cve/CVE-2011-4594>), Moderate)\n\nA previous update introduced an integer overflow flaw in the Linux kernel. On PowerPC systems, a local, unprivileged user could use this flaw to cause a denial of service. ([CVE-2011-4611 __](<https://access.redhat.com/security/cve/CVE-2011-4611>), Moderate)\n\nA 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 local, unprivileged user on the host could force this situation to occur, resulting in the host crashing. ([CVE-2011-4622 __](<https://access.redhat.com/security/cve/CVE-2011-4622>), Moderate)\n\nA flaw was found in the way the Linux kernel's XFS file system implementation handled on-disk Access Control Lists (ACLs). A local, unprivileged user could use this flaw to cause a denial of service or escalate their privileges by mounting a specially-crafted disk. ([CVE-2012-0038 __](<https://access.redhat.com/security/cve/CVE-2012-0038>), Moderate)\n\nA flaw was found in the way the Linux kernel's KVM hypervisor implementation emulated the syscall instruction for 32-bit guests. An unprivileged guest user could trigger this flaw to crash the guest. ([CVE-2012-0045 __](<https://access.redhat.com/security/cve/CVE-2012-0045>), Moderate)\n\nA 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 __](<https://access.redhat.com/security/cve/CVE-2012-0207>), Moderate)\n\n \n**Affected Packages:** \n\n\nkernel\n\n \n**Issue Correction:** \nRun _yum update kernel_ to update your system.
