  - The ims_pcu_get_cdc_union_desc function in     drivers/input/misc/ims-pcu.c in the Linux kernel,     through 4.13.11, allows local users to cause a denial     of service (ims_pcu_parse_cdc_data out-of-bounds read     and system crash) or possibly have unspecified other     impact via a crafted USB device.(CVE-2017-16645i1/4%0

  - It was found that due to excessive files_lock locking,     a soft lockup could be triggered in the Linux kernel     when performing asynchronous I/O operations. A local,     unprivileged user could use this flaw to crash the     system.(CVE-2014-8172i1/4%0

  - A flaw was discovered in the kernel's collect_mounts     function. If the kernel's audit subsystem called     collect_mounts to audit an unmounted path, it could     panic the system. With this flaw, an unprivileged user     could call umount(MNT_DETACH) to launch a     denial-of-service attack.(CVE-2015-4177i1/4%0

  - A flaw was found in the way the Linux kernel's floppy     driver handled user space provided data in certain     error code paths while processing FDRAWCMD IOCTL     commands. A local user with write access to /dev/fdX     could use this flaw to free (using the kfree()     function) arbitrary kernel memory. (CVE-2014-1737,     Important) was found that the Linux kernel's floppy     driver leaked internal kernel memory addresses to user     space during the processing of the FDRAWCMD IOCTL     command. A local user with write access to /dev/fdX     could use this flaw to obtain information about the     kernel heap arrangement. (CVE-2014-1738, Low)Note: A     local user with write access to /dev/fdX could use     these two flaws (CVE-2014-1737 in combination with     CVE-2014-1738) to escalate their privileges on the     system.(CVE-2014-1738i1/4%0

  - Use-after-free vulnerability in the     ffs_user_copy_worker function in     drivers/usb/gadget/function/f_fs.c in the Linux kernel     before 4.5.3 allows local users to gain privileges by     accessing an I/O data structure after a certain     callback call. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out, although we     believe it is unlikely.(CVE-2016-7912i1/4%0

  - A flaw was found in the way the get_dumpable() function     return value was interpreted in the ptrace subsystem of     the Linux kernel. When 'fs.suid_dumpable' was set to 2,     a local, unprivileged local user could use this flaw to     bypass intended ptrace restrictions and obtain     potentially sensitive information.(CVE-2013-2929i1/4%0

The following security issues have been addressed :

CVE-2013-6382: Multiple buffer underflows in the XFS implementation in the Linux kernel through 3.12.1 allow local users to cause a denial of service (memory corruption) or possibly have unspecified other impact by leveraging the CAP_SYS_ADMIN capability for a (1) XFS_IOC_ATTRLIST_BY_HANDLE or (2) XFS_IOC_ATTRLIST_BY_HANDLE_32 ioctl call with a crafted length value, related to the xfs_attrlist_by_handle function in fs/xfs/xfs_ioctl.c and the xfs_compat_attrlist_by_handle function in fs/xfs/xfs_ioctl32.c.
(bnc#852553)

Multiple vulnerabilities has been found and corrected in the Linux kernel :

The KVM subsystem in the Linux kernel through 3.12.5 allows local users to gain privileges or cause a denial of service (system crash) via a VAPIC synchronization operation involving a page-end address (CVE-2013-6368).

The apic_get_tmcct function in arch/x86/kvm/lapic.c in the KVM subsystem in the Linux kernel through 3.12.5 allows guest OS users to cause a denial of service (divide-by-zero error and host OS crash) via crafted modifications of the TMICT value (CVE-2013-6367).

Multiple buffer underflows in the XFS implementation in the Linux kernel through 3.12.1 allow local users to cause a denial of service (memory corruption) or possibly have unspecified other impact by leveraging the CAP_SYS_ADMIN capability for a (1) XFS_IOC_ATTRLIST_BY_HANDLE or (2) XFS_IOC_ATTRLIST_BY_HANDLE_32 ioctl call with a crafted length value, related to the xfs_attrlist_by_handle function in fs/xfs/xfs_ioctl.c and the xfs_compat_attrlist_by_handle function in fs/xfs/xfs_ioctl32.c (CVE-2013-6382).

Array index error in the kvm_vm_ioctl_create_vcpu function in virt/kvm/kvm_main.c in the KVM subsystem in the Linux kernel through 3.12.5 allows local users to gain privileges via a large id value (CVE-2013-4587).

The mISDN_sock_recvmsg function in drivers/isdn/mISDN/socket.c in the Linux kernel before 3.12.4 does not ensure that a certain length value is consistent with the size of an associated data structure, which allows local users to obtain sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call (CVE-2013-7266).

The atalk_recvmsg function in net/appletalk/ddp.c in the Linux kernel before 3.12.4 updates a certain length value without ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call (CVE-2013-7267).

The ipx_recvmsg function in net/ipx/af_ipx.c in the Linux kernel before 3.12.4 updates a certain length value without ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call (CVE-2013-7268).

The nr_recvmsg function in net/netrom/af_netrom.c in the Linux kernel before 3.12.4 updates a certain length value without ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call (CVE-2013-7269).

The packet_recvmsg function in net/packet/af_packet.c in the Linux kernel before 3.12.4 updates a certain length value before ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call (CVE-2013-7270).

The x25_recvmsg function in net/x25/af_x25.c in the Linux kernel before 3.12.4 updates a certain length value without ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call (CVE-2013-7271).

The Linux kernel before 3.12.4 updates certain length values before ensuring that associated data structures have been initialized, which allows local users to obtain sensitive information from kernel stack memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call, related to net/ipv4/ping.c, net/ipv4/raw.c, net/ipv4/udp.c, net/ipv6/raw.c, and net/ipv6/udp.c (CVE-2013-7263).

The l2tp_ip_recvmsg function in net/l2tp/l2tp_ip.c in the Linux kernel before 3.12.4 updates a certain length value before ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel stack memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call (CVE-2013-7264).

The pn_recvmsg function in net/phonet/datagram.c in the Linux kernel before 3.12.4 updates a certain length value before ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel stack memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call (CVE-2013-7265).

The dgram_recvmsg function in net/ieee802154/dgram.c in the Linux kernel before 3.12.4 updates a certain length value without ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel stack memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call (CVE-2013-7281).

The updated packages provides a solution for these security issues.
