[SUSE-SU-2016:1937-1] Security update for the Linux Kernel

The SUSE Linux Enterprise 12 SP1 RT kernel was updated to 3.12.61 to receive various security and bugfixes.

Main feature additions:
- Improved support for Clustered File System (CephFS, fate#318586).

The following security bugs were fixed:
- CVE-2014-9717: fs/namespace.c in the Linux kernel processes MNT_DETACH umount2 system calls without verifying that the MNT_LOCKED flag is unset, which allowed local users to bypass intended access restrictions and navigate to filesystem locations beneath a mount by calling umount2 within a user namespace (bnc#928547).
- CVE-2014-9904: The snd_compress_check_input function in sound/core/compress_offload.c in the ALSA subsystem in the Linux kernel did not properly check for an integer overflow, which allowed local users to cause a denial of service (insufficient memory allocation) or possibly have unspecified other impact via a crafted SNDRV_COMPRESS_SET_PARAMS ioctl call (bnc#986811).
- CVE-2015-7833: The usbvision driver in the Linux kernel allowed physically proximate attackers to cause a denial of service (panic) via a nonzero bInterfaceNumber value in a USB device descriptor (bnc#950998).
- CVE-2015-8539: The KEYS subsystem in the Linux kernel allowed local users to gain privileges or cause a denial of service (BUG) via crafted keyctl commands that negatively instantiate a key, related to security/keys/encrypted-keys/encrypted.c, security/keys/trusted.c, and security/keys/user_defined.c (bnc#958463).
- CVE-2015-8551: The PCI backend driver in Xen, when running on an x86 system, allowed local guest administrators to hit BUG conditions and cause a denial of service (NULL pointer dereference and host OS crash) by leveraging a system with access to a passed-through MSI or MSI-X capable physical PCI device and a crafted sequence of XEN_PCI_OP_* operations, aka 'Linux pciback missing sanity checks (bnc#957990).
- CVE-2015-8552: The PCI backend driver in Xen, when running on an x86 system, allowed local guest administrators to generate a continuous stream of WARN messages and cause a denial of service (disk consumption) by leveraging a system with access to a passed-through MSI or MSI-X capable physical PCI device and XEN_PCI_OP_enable_msi operations, aka 'Linux pciback missing sanity checks (bnc#957990).
- CVE-2015-8845: The tm_reclaim_thread function in arch/powerpc/kernel/process.c in the Linux kernel on powerpc platforms did not ensure that TM suspend mode exists before proceeding with a tm_reclaim call, which allowed local users to cause a denial of service (TM Bad Thing exception and panic) via a crafted application (bnc#975533).
- CVE-2016-0758: Integer overflow in lib/asn1_decoder.c in the Linux kernel allowed local users to gain privileges via crafted ASN.1 data (bnc#979867).
- CVE-2016-1583: The ecryptfs_privileged_open function in fs/ecryptfs/kthread.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (stack memory consumption) via vectors involving crafted mmap calls for /proc pathnames, leading to recursive pagefault handling (bnc#983143).
- CVE-2016-2053: The asn1_ber_decoder function in lib/asn1_decoder.c in the Linux kernel allowed attackers to cause a denial of service (panic) via an ASN.1 BER file that lacks a public key, leading to mishandling by the public_key_verify_signature function in crypto/asymmetric_keys/public_key.c (bnc#963762).
- CVE-2016-2847: fs/pipe.c in the Linux kernel did not limit the amount of unread data in pipes, which allowed local users to cause a denial of service (memory consumption) by creating many pipes with non-default sizes (bnc#970948).
- CVE-2016-3672: The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel did not properly randomize the legacy base address, which made it easier for local users to defeat the intended restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or setgid program, by disabling stack-consumption resource limits (bnc#974308).
- CVE-2016-3707: The icmp_check_sysrq function in net/ipv4/icmp.c in the kernel.org projects/rt patches for the Linux kernel allowed remote attackers to execute SysRq commands via crafted ICMP Echo Request packets, as demonstrated by a brute-force attack to discover a cookie, or an attack that occurs after reading the local icmp_echo_sysrq file (bnc#980246).
- CVE-2016-4470: The key_reject_and_link function in security/keys/key.c in the Linux kernel did not ensure that a certain data structure is initialized, which allowed local users to cause a denial of service (system crash) via vectors involving a crafted keyctl request2 command (bnc#984755).
- CVE-2016-4482: The proc_connectinfo function in drivers/usb/core/devio.c in the Linux kernel did not initialize a certain data structure, which allowed local users to obtain sensitive information from kernel stack memory via a crafted USBDEVFS_CONNECTINFO ioctl call (bnc#978401).
- CVE-2016-4486: The rtnl_fill_link_ifmap function in net/core/rtnetlink.c in the Linux kernel did not initialize a certain data structure, which allowed local users to obtain sensitive information from kernel stack memory by reading a Netlink message (bnc#978822).
- CVE-2016-4565: The InfiniBand (aka IB) stack in the Linux kernel incorrectly relies on the write system call, which allowed local users to cause a denial of service (kernel memory write operation) or possibly have unspecified other impact via a uAPI interface (bnc#979548).
- CVE-2016-4569: The snd_timer_user_params function in sound/core/timer.c in the Linux kernel did not initialize a certain data structure, which allowed local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface (bnc#979213).
- CVE-2016-4578: sound/core/timer.c in the Linux kernel did not initialize certain r1 data structures, which allowed local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface, related to the (1) snd_timer_user_ccallback and (2) snd_timer_user_tinterrupt functions (bnc#979879).
- CVE-2016-4805: Use-after-free vulnerability in drivers/net/ppp/ppp_generic.c in the Linux kernel allowed local users to cause a denial of service (memory corruption and system crash, or spinlock) or possibly have unspecified other impact by removing a network namespace, related to the ppp_register_net_channel and ppp_unregister_channel functions (bnc#980371).
- CVE-2016-4997: The compat IPT_SO_SET_REPLACE setsockopt implementation in the netfilter subsystem in the Linux kernel allowed local users to gain privileges or cause a denial of service (memory corruption) by leveraging in-container root access to provide a crafted offset value that triggers an unintended decrement (bnc#986362).
- CVE-2016-5244: The rds_inc_info_copy function in net/rds/recv.c in the Linux kernel did not initialize a certain structure member, which allowed remote attackers to obtain sensitive information from kernel stack memory by reading an RDS message (bnc#983213).
- CVE-2016-5828: The start_thread function in arch/powerpc/kernel/process.c in the Linux kernel on powerpc platforms mishandled transactional state, which allowed local users to cause a denial of service (invalid process state or TM Bad Thing exception, and system crash) or possibly have unspecified other impact by starting and suspending a transaction before an exec system call (bnc#986569).
- CVE-2016-5829: Multiple heap-based buffer overflows in the hiddev_ioctl_usage function in drivers/hid/usbhid/hiddev.c in the Linux kernel allowed local users to cause a denial of service or possibly have unspecified other impact via a crafted (1) HIDIOCGUSAGES or (2) HIDIOCSUSAGES ioctl call (bnc#986572).
