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