Updated kernel packages that fix multiple security issues, address several hundred bugs, and add numerous enhancements are now available as part of the ongoing support and maintenance of Red Hat Enterprise Linux version 6. This is the fifth regular update.

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 kernel packages contain the Linux kernel, the core of any Linux operating system.

This update fixes the following security issues :

* A flaw was found in the way the Linux kernel's IPv6 implementation handled certain UDP packets when the UDP Fragmentation Offload (UFO) feature was enabled. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system.
(CVE-2013-4387, Important)

* A flaw was found in the way the Linux kernel handled the creation of temporary IPv6 addresses. If the IPv6 privacy extension was enabled (/proc/sys/net/ipv6/conf/eth0/use_tempaddr set to '2'), an attacker on the local network could disable IPv6 temporary address generation, leading to a potential information disclosure. (CVE-2013-0343, Moderate)

* A flaw was found in the way the Linux kernel handled HID (Human Interface Device) reports with an out-of-bounds Report ID. An attacker with physical access to the system could use this flaw to crash the system or, potentially, escalate their privileges on the system.
(CVE-2013-2888, Moderate)

* An off-by-one flaw was found in the way the ANSI CPRNG implementation in the Linux kernel processed non-block size aligned requests. This could lead to random numbers being generated with less bits of entropy than expected when ANSI CPRNG was used.
(CVE-2013-4345, Moderate)

* It was found that the fix for CVE-2012-2375 released via RHSA-2012:1580 accidentally removed a check for small-sized result buffers. A local, unprivileged user with access to an NFSv4 mount with ACL support could use this flaw to crash the system or, potentially, escalate their privileges on the system . (CVE-2013-4591, Moderate)

* A flaw was found in the way IOMMU memory mappings were handled when moving memory slots. A malicious user on a KVM host who has the ability to assign a device to a guest could use this flaw to crash the host. (CVE-2013-4592, Moderate)

* Heap-based buffer overflow flaws were found in the way the Zeroplus and Pantherlord/GreenAsia game controllers handled HID reports. An attacker with physical access to the system could use these flaws to crash the system or, potentially, escalate their privileges on the system. (CVE-2013-2889, CVE-2013-2892, Moderate)

* Two information leak flaws were found in the logical link control (LLC) implementation in the Linux kernel. A local, unprivileged user could use these flaws to leak kernel stack memory to user space.
(CVE-2012-6542, CVE-2013-3231, Low)

* A heap-based buffer overflow in the way the tg3 Ethernet driver parsed the vital product data (VPD) of devices could allow an attacker with physical access to a system to cause a denial of service or, potentially, escalate their privileges. (CVE-2013-1929, Low)

* Information leak flaws in the Linux kernel could allow a privileged, local user to leak kernel memory to user space. (CVE-2012-6545, CVE-2013-1928, CVE-2013-2164, CVE-2013-2234, Low)

* A format string flaw was found in the Linux kernel's block layer. A privileged, local user could potentially use this flaw to escalate their privileges to kernel level (ring0). (CVE-2013-2851, Low)

The openSUSE 12.1 kernel was updated to fix a severe secrutiy issue and various bugs.

Security issues fixed: CVE-2013-2094: The perf_swevent_init function in kernel/events/core.c in the Linux kernel used an incorrect integer data type, which allowed local users to gain privileges via a crafted perf_event_open system 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-2013-1928: The do_video_set_spu_palette function in fs/compat_ioctl.c in the Linux kernel lacked a certain error check, which might have allowed local users to obtain sensitive information from kernel stack memory via a crafted VIDEO_SET_SPU_PALETTE ioctl call on a /dev/dvb device.

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 allowed 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-2013-1767: 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 cause a denial of service (system crash) by remounting a tmpfs filesystem without specifying a required mpol (aka mempolicy) mount option.

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.
