    description Updated rhev-hypervisor packages that fix multiple security issues and two bugs are 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-hypervisor 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. It was found that the libspice component of QEMU-KVM on the host did not validate all pointers provided from a guest system's QXL graphics card driver. A privileged guest user could use this flaw to cause the host to dereference an invalid pointer, causing the guest to crash (denial of service) or, possibly, resulting in the privileged guest user escalating their privileges on the host. (CVE-2010-0428) It was found that the libspice component of QEMU-KVM on the host could be forced to perform certain memory management operations on memory addresses controlled by a guest. A privileged guest user could use this flaw to crash the guest (denial of service) or, possibly, escalate their privileges on the host. (CVE-2010-0429) It was found that QEMU-KVM on the host did not validate all pointers provided from a guest system's QXL graphics card driver. A privileged guest user could use this flaw to cause the host to dereference an invalid pointer, causing the guest to crash (denial of service) or, possibly, resulting in the privileged guest user escalating their privileges on the host. (CVE-2010-0431) A flaw was found in QEMU-KVM, allowing the guest some control over the index used to access the callback array during sub-page MMIO initialization. A privileged guest user could use this flaw to crash the guest (denial of service) or, possibly, escalate their privileges on the host. (CVE-2010-2784) A NULL pointer dereference flaw was found when Red Hat Enterprise Virtualization Hypervisor was run on a system that has a processor with the Intel VT-x extension enabled. A privileged guest user could use this flaw to trick the host into emulating a certain instruction, which could crash the host (denial of service). (CVE-2010-0435) A flaw was found in the way VDSM accepted SSL connections. An attacker could trigger this flaw by creating a crafted SSL connection to VDSM, preventing VDSM from accepting SSL connections from other users. (CVE-2010-2811) These updated packages provide updated components that include fixes for security issues; however, these issues have no security impact for Red Hat Enterprise Virtualization Hypervisor. These fixes are for avahi issues CVE-2009-0758 and CVE-2010-2244; freetype issues CVE-2010-1797, CVE-2010-2498, CVE-2010-2499, CVE-2010-2500, CVE-2010-2519, CVE-2010-2527, and CVE-2010-2541; kernel issues CVE-2010-1084, CVE-2010-2066, CVE-2010-2070, CVE-2010-2226, CVE-2010-2248, CVE-2010-2521, and CVE-2010-2524; and openldap issues CVE-2010-0211 and CVE-2010-0212. These updated rhev-hypervisor packages also fix two bugs. Documentation for these bug fixes will be available shortly from http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Virtualization_fo r_Servers /2.2/html/Technical_Notes/index.html As Red Hat Enterprise Virtualization Hypervisor is based on KVM, the bug fixes from the KVM update RHSA-2010:0627 have been included in this update. Also included are the bug fixes from the VDSM update RHSA-2010:0628. KVM: https://rhn.redhat.com/errata/RHSA-2010-0627.html VDSM: https://rhn.redhat.com/errata/RHSA-2010-0628.html Users of Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to these updated rhev-hypervisor packages, which resolve these issues.

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. 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 Red Hat Enterprise Linux kernel. It was found that QEMU-KVM on the host did not validate all pointers provided from a guest system's QXL graphics card driver.

(CVE-2010-0435) This update also fixes the following bugs : * running a 'qemu-img' check on a faulty virtual machine image ended with a segmentation fault. With this update, the segmentation fault no longer occurs when running the 'qemu-img' check. (BZ#610342) * when attempting to transfer a file between two guests that were joined in the same virtual LAN (VLAN), the receiving guest unexpectedly quit. With this update, the transfer completes successfully. (BZ#610343) * installation of a system was occasionally failing in KVM. This was caused by KVM using wrong permissions for large guest pages. With this update, the installation completes successfully. (BZ#616796) * previously, the migration process would fail for a virtual machine because the virtual machine could not map all the memory. This was caused by a conflict that was initiated when a virtual machine was initially run and then migrated right away. With this update, the conflict no longer occurs and the migration process no longer fails. (BZ#618205) * using a thinly provisioned VirtIO disk on iSCSI storage and performing a 'qemu-img' check during an 'e_no_space' event returned cluster errors. With this update, the errors no longer appear. (BZ#618206) All KVM users should upgrade to these updated packages, which contain backported patches to resolve these issues. Note: The procedure in the Solution section must be performed before this update will take effect.

    description Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leak. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2010-0435 Gleb Napatov reported an issue in the KVM subsystem that allows virtual machines to cause a denial of service of the host machine by executing mov to/from DR instructions. - CVE-2010-3699 Keir Fraser provided a fix for an issue in the Xen subsystem. A guest can cause a denial of service on the host by retaining a leaked reference to a device. This can result in a zombie domain, xenwatch process hangs, and xm command failures. - CVE-2010-4158 Dan Rosenberg discovered an issue in the socket filters subsystem, allowing local unprivileged users to obtain the contents of sensitive kernel memory. - CVE-2010-4162 Dan Rosenberg discovered an overflow issue in the block I/O subsystem that allows local users to map large numbers of pages, resulting in a denial of service due to invocation of the out of memory killer. - CVE-2010-4163 Dan Rosenberg discovered an issue in the block I/O subsystem. Due to improper validation of iov segments, local users can trigger a kernel panic resulting in a denial of service. - CVE-2010-4242 Alan Cox reported an issue in the Bluetooth subsystem. Local users with sufficient permission to access HCI UART devices can cause a denial of service (NULL pointer dereference) due to a missing check for an existing tty write operation. - CVE-2010-4243 Brad Spengler reported a denial-of-service issue in the kernel memory accounting system. By passing large argv/envp values to exec, local users can cause the out of memory killer to kill processes owned by other users. - CVE-2010-4248 Oleg Nesterov reported an issue in the POSIX CPU timers subsystem. Local users can cause a denial of service (Oops) due to incorrect assumptions about thread group leader behavior. - CVE-2010-4249 Vegard Nossum reported an issue with the UNIX socket garbage collector. Local users can consume all of LOWMEM and decrease system performance by overloading the system with inflight sockets. - CVE-2010-4258 Nelson Elhage reported an issue in Linux oops handling. Local users may be able to obtain elevated privileges if they are able to trigger an oops with a process' fs set to KERNEL_DS. - CVE-2010-4342 Nelson Elhage reported an issue in the Econet protocol. Remote attackers can cause a denial of service by sending an Acorn Universal Networking packet over UDP. - CVE-2010-4346 Tavis Ormandy discovered an issue in the install_special_mapping routine which allows local users to bypass the mmap_min_addr security restriction. Combined with an otherwise low severity local denial of service vulnerability (NULL pointer dereference), a local user could obtain elevated privileges. - CVE-2010-4526 Eugene Teo reported a race condition in the Linux SCTP implementation. Remote users can cause a denial of service (kernel memory corruption) by transmitting an ICMP unreachable message to a locked socket. - CVE-2010-4527 Dan Rosenberg reported two issues in the OSS soundcard driver. Local users with access to the device (members of group 'audio' on default Debian installations) may access to sensitive kernel memory or cause a buffer overflow, potentially leading to an escalation of privileges. - CVE-2010-4529 Dan Rosenberg reported an issue in the Linux kernel IrDA socket implementation on non-x86 architectures. Local users may be able to gain access to sensitive kernel memory via a specially crafted IRLMP_ENUMDEVICES getsockopt call. - CVE-2010-4565 Dan Rosenberg reported an issue in the Linux CAN protocol implementation. Local users can obtain the address of a kernel heap object which might help facilitate system exploitation. - CVE-2010-4649 Dan Carpenter reported an issue in the uverb handling of the InfiniBand subsystem. A potential buffer overflow may allow local users to cause a denial of service (memory corruption) by passing in a large cmd.ne value. - CVE-2010-4656 Kees Cook reported an issue in the driver for I/O-Warrior USB devices. Local users with access to these devices may be able to overrun kernel buffers, resulting in a denial of service or privilege escalation. - CVE-2010-4668 Dan Rosenberg reported an issue in the block subsystem. A local user can cause a denial of service (kernel panic) by submitting certain 0-length I/O requests. - CVE-2011-0521 Dan Carpenter reported an issue in the DVB driver for AV7110 cards. Local users can pass a negative info->num value, corrupting kernel memory and causing a denial of service.

    description From Red Hat Security Advisory 2010:0627 : Updated kvm packages that fix three security issues and multiple bugs are now available for Red Hat Enterprise Linux 5. 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. 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 Red Hat Enterprise Linux kernel. It was found that QEMU-KVM on the host did not validate all pointers provided from a guest system's QXL graphics card driver. A privileged guest user could use this flaw to cause the host to dereference an invalid pointer, causing the guest to crash (denial of service) or, possibly, resulting in the privileged guest user escalating their privileges on the host. (CVE-2010-0431) A flaw was found in QEMU-KVM, allowing the guest some control over the index used to access the callback array during sub-page MMIO initialization. A privileged guest user could use this flaw to crash the guest (denial of service) or, possibly, escalate their privileges on the host. (CVE-2010-2784) A NULL pointer dereference flaw was found when the host system had a processor with the Intel VT-x extension enabled. A privileged guest user could use this flaw to trick the host into emulating a certain instruction, which could crash the host (denial of service). (CVE-2010-0435) This update also fixes the following bugs : * running a 'qemu-img' check on a faulty virtual machine image ended with a segmentation fault. With this update, the segmentation fault no longer occurs when running the 'qemu-img' check. (BZ#610342) * when attempting to transfer a file between two guests that were joined in the same virtual LAN (VLAN), the receiving guest unexpectedly quit. With this update, the transfer completes successfully. (BZ#610343) * installation of a system was occasionally failing in KVM. This was caused by KVM using wrong permissions for large guest pages. With this update, the installation completes successfully. (BZ#616796) * previously, the migration process would fail for a virtual machine because the virtual machine could not map all the memory. This was caused by a conflict that was initiated when a virtual machine was initially run and then migrated right away. With this update, the conflict no longer occurs and the migration process no longer fails. (BZ#618205) * using a thinly provisioned VirtIO disk on iSCSI storage and performing a 'qemu-img' check during an 'e_no_space' event returned cluster errors. With this update, the errors no longer appear. (BZ#618206) All KVM users should upgrade to these updated packages, which contain backported patches to resolve these issues. Note: The procedure in the Solution section must be performed before this update will take effect.

    NASL id SUSE_11_3_KERNEL-101215.NASL
    description The openSUSE 11.3 kernel was updated to fix various bugs and security issues. Following security issues have been fixed: CVE-2010-4347: A local user could inject ACPI code into the kernel via the world-writable 'custom_debug' file, allowing local privilege escalation. CVE-2010-4258: A local attacker could use a Oops (kernel crash) caused by other flaws to write a 0 byte to a attacker controlled address in the kernel. This could lead to privilege escalation together with other issues. CVE-2010-4157: A 32bit vs 64bit integer mismatch in gdth_ioctl_alloc could lead to memory corruption in the GDTH driver. CVE-2010-4165: The do_tcp_setsockopt function in net/ipv4/tcp.c in the Linux kernel did not properly restrict TCP_MAXSEG (aka MSS) values, which allows local users to cause a denial of service (OOPS) via a setsockopt call that specifies a small value, leading to a divide-by-zero error or incorrect use of a signed integer.

CVE-2010-3874: A minor heap overflow in the CAN network module was fixed. Due to nature of the memory allocator it is likely not exploitable. CVE-2010-4158: A memory information leak in berkely packet filter rules allowed local attackers to read uninitialized memory of the kernel stack. CVE-2010-4162: A local denial of service in the blockdevice layer was fixed. CVE-2010-4163: By submitting certain I/O requests with 0 length, a local user could have caused a kernel panic. CVE-2010-0435: The Hypervisor in KVM 83, when the Intel VT-x extension is enabled, allows guest OS users to cause a denial of service (NULL pointer dereference and host OS crash) via vectors related to instruction emulation. CVE-2010-3861: The ethtool_get_rxnfc function in net/core/ethtool.c in the Linux kernel did not initialize a certain block of heap memory, which allowed local users to obtain potentially sensitive information via an ETHTOOL_GRXCLSRLALL ethtool command with a large info.rule_cnt value. CVE-2010-3442: Multiple integer overflows in the snd_ctl_new function in sound/core/control.c in the Linux kernel allowed local users to cause a denial of service (heap memory corruption) or possibly have unspecified other impact via a crafted (1) SNDRV_CTL_IOCTL_ELEM_ADD or (2) SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl call. CVE-2010-3437: A range checking overflow in pktcdvd ioctl was fixed. CVE-2010-4078: The sisfb_ioctl function in drivers/video/sis/sis_main.c in the Linux kernel did not properly initialize a certain structure member, which allowed local users to obtain potentially sensitive information from kernel stack memory via an FBIOGET_VBLANK ioctl call. CVE-2010-4080: The snd_hdsp_hwdep_ioctl function in sound/pci/rme9652/hdsp.c in the Linux kernel did not initialize a certain structure, which allowed local users to obtain potentially sensitive information from kernel stack memory via an SNDRV_HDSP_IOCTL_GET_CONFIG_INFO ioctl call. CVE-2010-4081: The snd_hdspm_hwdep_ioctl function in sound/pci/rme9652/hdspm.c in the Linux kernel did not initialize a certain structure, which allowed local users to obtain potentially sensitive information from kernel stack memory via an SNDRV_HDSPM_IOCTL_GET_CONFIG_INFO ioctl call. CVE-2010-4082: The viafb_ioctl_get_viafb_info function in drivers/video/via/ioctl.c in the Linux kernel did not properly initialize a certain structure member, which allowed local users to obtain potentially sensitive information from kernel stack memory via a VIAFB_GET_INFO ioctl call. CVE-2010-4073: The ipc subsystem in the Linux kernel did not initialize certain structures, which allowed local users to obtain potentially sensitive information from kernel stack memory via vectors related to the (1) compat_sys_semctl, (2) compat_sys_msgctl, and (3) compat_sys_shmctl functions in ipc/compat.c; and the (4) compat_sys_mq_open and (5) compat_sys_mq_getsetattr functions in ipc/compat_mq.c. CVE-2010-4072: The copy_shmid_to_user function in ipc/shm.c in the Linux kernel did not initialize a certain structure, which allowed local users to obtain potentially sensitive information from kernel stack memory via vectors related to the shmctl system call and the 'old shm interface.' CVE-2010-4083: The copy_semid_to_user function in ipc/sem.c in the Linux kernel did not initialize a certain structure, which allowed local users to obtain potentially sensitive information from kernel stack memory via a (1) IPC_INFO, (2) SEM_INFO, (3) IPC_STAT, or (4) SEM_STAT command in a semctl system call. CVE-2010-3432: The sctp_packet_config function in net/sctp/output.c in the Linux kernel performed extraneous initializations of packet data structures, which allowed remote attackers to cause a denial of service (panic) via a certain sequence of SCTP traffic. CVE-2010-3067: Integer overflow in the do_io_submit function in fs/aio.c in the Linux kernel allowed local users to cause a denial of service or possibly have unspecified other impact via crafted use of the io_submit system call. CVE-2010-3865: A iovec integer overflow in RDS sockets was fixed which could lead to local attackers gaining kernel privileges.
