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

The following security bugs were fixed :

CVE-2018-14634: Prevent integer overflow in create_elf_tables that allowed a local attacker to exploit this vulnerability via a SUID-root binary and obtain full root privileges (bsc#1108912)

CVE-2018-14617: Prevent NULL pointer dereference and panic in hfsplus_lookup() when opening a file (that is purportedly a hard link) in an hfs+ filesystem that has malformed catalog data, and is mounted read-only without a metadata directory (bsc#1102870)

CVE-2018-16276: Incorrect bounds checking in the yurex USB driver in yurex_read allowed local attackers to use user access read/writes to crash the kernel or potentially escalate privileges (bsc#1106095)

CVE-2018-12896: Prevent integer overflow in the POSIX timer code that was caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically made the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. This allowed a local user to cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls (bnc#1099922)

CVE-2018-13093: Prevent NULL pointer dereference and panic in lookup_slow() on a NULL inode->i_ops pointer when doing pathwalks on a corrupted xfs image. This occured because of a lack of proper validation that cached inodes are free during allocation (bnc#1100001)

CVE-2018-10940: The cdrom_ioctl_media_changed function allowed local attackers to use a incorrect bounds check in the CDROM driver CDROM_MEDIA_CHANGED ioctl to read out kernel memory (bsc#1092903)

CVE-2018-16658: Prevent information leak in cdrom_ioctl_drive_status that could have been used by local attackers to read kernel memory (bnc#1107689)

CVE-2018-6555: The irda_setsockopt function allowed local users to cause a denial of service (ias_object use-after-free and system crash) or possibly have unspecified other impact via an AF_IRDA socket (bnc#1106511)

CVE-2018-6554: Prevent memory leak in the irda_bind function that allowed local users to cause a denial of service (memory consumption) by repeatedly binding an AF_IRDA socket (bnc#1106509)

CVE-2018-10902: Protect against concurrent access to prevent double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status(). A malicious local attacker could have used this for privilege escalation (bnc#1105322)

CVE-2018-10879: A local user could have caused a use-after-free in ext4_xattr_set_entry function and a denial of service or unspecified other impact by renaming a file in a crafted ext4 filesystem image (bsc#1099844)

CVE-2018-10883: A local user could have caused an out-of-bounds write in jbd2_journal_dirty_metadata(), a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image (bsc#1099863)

CVE-2018-10880: Prevent stack-out-of-bounds write in the ext4 filesystem code when mounting and writing to a crafted ext4 image in ext4_update_inline_data(). An attacker could have used this to cause a system crash and a denial of service (bsc#1099845)

CVE-2018-10882: A local user could have caused an out-of-bound write, a denial of service, and a system crash by unmounting a crafted ext4 filesystem image (bsc#1099849)

CVE-2018-10881: A local user could have caused an out-of-bound access in ext4_get_group_info function, a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image (bsc#1099864)

CVE-2018-10877: Prevent out-of-bound access in the ext4_ext_drop_refs() function when operating on a crafted ext4 filesystem image (bsc#1099846)

CVE-2018-10876: A use-after-free was possible in ext4_ext_remove_space() function when mounting and operating a crafted ext4 image (bsc#1099811)

CVE-2018-10878: A local user could have caused an out-of-bounds write and a denial of service or unspecified other impact by mounting and operating a crafted ext4 filesystem image (bsc#1099813)

CVE-2018-10853: The KVM hypervisor did not check current privilege(CPL) level while emulating unprivileged instructions. An unprivileged guest user/process could have used this flaw to potentially escalate privileges inside guest (bsc#1097104).

The update package also includes non-security fixes. See advisory for details.

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc.Security Fix(es):** DISPUTED ** Multiple     integer overflows in the lzo1x_decompress_safe function     in lib/lzo/lzo1x_decompress_safe.c in the LZO     decompressor in the Linux kernel before 3.15.2 allow     context-dependent attackers to cause a denial of     service (memory corruption) via a crafted Literal Run.
    NOTE: the author of the LZO algorithms says 'the Linux     kernel is *not* affected media hype.'(CVE-2014-4608)A     certain backport in the TCP Fast Open implementation     for the Linux kernel before 3.18 does not properly     maintain a count value, which allow local users to     cause a denial of service (system crash) via the Fast     Open feature, as demonstrated by visiting the     chrome://flags/#enable-tcp-fast-open URL when using     certain 3.10.x through 3.16.x kernel builds, including     longterm-maintenance releases and ckt (aka Canonical     Kernel Team) builds.(CVE-2015-3332)An elevation of     privilege vulnerability in the kernel scsi driver.
    Product: Android. Versions: Android kernel. Android ID     A-65023233.(CVE-2017-13168)An issue was discovered in     drivers/i2c/i2c-core-smbus.c in the Linux kernel before     4.14.15. There is an out of bounds write in the     function i2c_smbus_xfer_emulated.(CVE-2017-18551)An     issue was discovered in net/ipv6/ip6mr.c in the Linux     kernel before 4.11. By setting a specific socket     option, an attacker can control a pointer in kernel     land and cause an inet_csk_listen_stop general     protection fault, or potentially execute arbitrary code     under certain circumstances. The issue can be triggered     as root (e.g., inside a default LXC container or with     the CAP_NET_ADMIN capability) or after namespace     unsharing. This occurs because sk_type and protocol are     not checked in the appropriate part of the ip6_mroute_*     functions. NOTE: this affects Linux distributions that     use 4.9.x longterm kernels before     4.9.187.(CVE-2017-18509)An issue was discovered in the     Linux kernel before 4.14.11. A double free may be     caused by the function allocate_trace_buffer in the     file kernel/trace/trace.c.(CVE-2017-18595)An issue was     discovered in the Linux kernel through 4.17.10. There     is a NULL pointer dereference and panic in     hfsplus_lookup() in fs/hfsplus/dir.c when opening a     file (that is purportedly a hard link) in an hfs+     filesystem that has malformed catalog data, and is     mounted read-only without a metadata     directory.(CVE-2018-14617)An issue was discovered in     write_tpt_entry in drivers/infiniband/hw/cxgb4/mem.c in     the Linux kernel through 5.3.2. The cxgb4 driver is     directly calling dma_map_single (a DMA function) from a     stack variable. This could allow an attacker to trigger     a Denial of Service, exploitable if this driver is used     on an architecture for which this stack/DMA interaction     has security relevance.(CVE-2019-17075)Double free     vulnerability in the snd_usbmidi_create function in     sound/usb/midi.c in the Linux kernel before 4.5 allows     physically proximate attackers to cause a denial of     service (panic) or possibly have unspecified other     impact via vectors involving an invalid USB     descriptor.(CVE-2016-2384)fsamespace.c in the Linux     kernel through 3.16.1 does not properly restrict     clearing MNT_NODEV, MNT_NOSUID, and MNT_NOEXEC and     changing MNT_ATIME_MASK during a remount of a bind     mount, which allows local users to gain privileges,     interfere with backups and auditing on systems that had     atime enabled, or cause a denial of service (excessive     filesystem updating) on systems that had atime disabled     via a 'mount -o remount' command within a user     namespace.(CVE-2014-5207)fs/overlayfs/dir.c in the     OverlayFS filesystem implementation in the Linux kernel     before 4.6 does not properly verify the upper dentry     before proceeding with unlink and rename system-call     processing, which allows local users to cause a denial     of service (system crash) via a rename system call that     specifies a self-hardlink.(CVE-2016-6197)In the Linux     kernel before 4.1.4, a buffer overflow occurs when     checking userspace params in     drivers/media/dvb-frontends/cx24116.c. The maximum size     for a DiSEqC command is 6, according to the userspace     API. However, the code allows larger values such as     23.(CVE-2015-9289)In the Linux kernel through 5.3.2,     cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c     does not reject a long SSID IE, leading to a Buffer     Overflow.(CVE-2019-17133)Insufficient access control in     the Intel(R) PROSet/Wireless WiFi Software driver     before version 21.10 may allow an unauthenticated user     to potentially enable denial of service via adjacent     access.(CVE-2019-0136)Linux distributions that have not     patched their long-term kernels with     https://git.kernel.org/linus/a87938b2e246b81b4fb713edb3     71a9fa3c5c3c86 (committed on April 14, 2015). This     kernel vulnerability was fixed in April 2015 by commit     a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (backported to     Linux 3.10.77 in May 2015), but it was not recognized     as a security threat. With     CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE enabled, and a     normal top-down address allocation strategy,     load_elf_binary() will attempt to map a PIE binary into     an address range immediately below mm->mmap_base.
    Unfortunately, load_elf_ binary() does not take account     of the need to allocate sufficient space for the entire     binary which means that, while the first PT_LOAD     segment is mapped below mm->mmap_base, the subsequent     PT_LOAD segment(s) end up being mapped above     mm->mmap_base into the are that is supposed to be the     'gap' between the stack and the     binary.(CVE-2017-1000253)Race condition in the     sclp_ctl_ioctl_sccb function in     drivers/s390/char/sclp_ctl.c in the Linux kernel before     4.6 allows local users to obtain sensitive information     from kernel memory by changing a certain length value,     aka a 'double fetch'     vulnerability.(CVE-2016-6130)rtl_p2p_noa_ie in drivers     et/wireless/realtek/rtlwifi/ps.c in the Linux kernel     through 5.3.6 lacks a certain upper-bound check,     leading to a buffer     overflow.(CVE-2019-17666)sound/core/timer.c in the     Linux kernel through 4.6 does not initialize certain r1     data structures, which allows 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.(CVE-2016-4578)Systems with microprocessors     utilizing speculative execution and branch prediction     may allow unauthorized disclosure of information to an     attacker with local user access via a side-channel     analysis.(CVE-2017-5753)The acm_probe function in     drivers/usb/class/cdc-acm.c in the Linux kernel before     4.5.1 allows physically proximate attackers to cause a     denial of service (NULL pointer dereference and system     crash) via a USB device without both a control and a     data endpoint descriptor.(CVE-2016-3138)The     arcmsr_iop_message_xfer function in     drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel     through 4.8.2 does not restrict a certain length field,     which allows local users to gain privileges or cause a     denial of service (heap-based buffer overflow) via an     ARCMSR_MESSAGE_WRITE_WQBUFFER control     code.(CVE-2016-7425)The ati_remote2_probe function in     drivers/input/misc/ati_remote2.c in the Linux kernel     before 4.5.1 allows physically proximate attackers to     cause a denial of service (NULL pointer dereference and     system crash) via a crafted endpoints value in a USB     device descriptor.(CVE-2016-2185)The     create_fixed_stream_quirk function in     sound/usb/quirks.c in the snd-usb-audio driver in the     Linux kernel before 4.5.1 allows physically proximate     attackers to cause a denial of service (NULL pointer     dereference or double free, and system crash) via a     crafted endpoints value in a USB device     descriptor.(CVE-2016-2184)The digi_port_init function     in drivers/usb/serial/digi_acceleport.c in the Linux     kernel before 4.5.1 allows physically proximate     attackers to cause a denial of service (NULL pointer     dereference and system crash) via a crafted endpoints     value in a USB device descriptor.(CVE-2016-3140)The     do_remount function in fsamespace.c in the Linux kernel     through 3.16.1 does not maintain the MNT_LOCK_READONLY     bit across a remount of a bind mount, which allows     local users to bypass an intended read-only restriction     and defeat certain sandbox protection mechanisms via a     'mount -o remount' command within a user     namespace.(CVE-2014-5206)The gtco_probe function in     drivers/input/tablet/gtco.c in the Linux kernel through     4.5.2 allows physically proximate attackers to cause a     denial of service (NULL pointer dereference and system     crash) via a crafted endpoints value in a USB device     descriptor.(CVE-2016-2187)The hub_activate function in     drivers/usb/core/hub.c in the Linux kernel before 4.3.5     does not properly maintain a hub-interface data     structure, which allows physically proximate attackers     to cause a denial of service (invalid memory access and     system crash) or possibly have unspecified other impact     by unplugging a USB hub device.(CVE-2015-8816)The     ims_pcu_parse_cdc_data function in     drivers/input/misc/ims-pcu.c in the Linux kernel before     4.5.1 allows physically proximate attackers to cause a     denial of service (system crash) via a USB device     without both a master and a slave     interface.(CVE-2016-3689)The Linux Kernel running on     AMD64 systems will sometimes map the contents of PIE     executable, the heap or ld.so to where the stack is     mapped allowing attackers to more easily manipulate the     stack. Linux Kernel version 4.11.5 is     affected.(CVE-2017-1000379)The powermate_probe function     in drivers/input/misc/powermate.c in the Linux kernel     before 4.5.1 allows physically proximate attackers to     cause a denial of service (NULL pointer dereference and     system crash) via a crafted endpoints value in a USB     device descriptor.(CVE-2016-2186)The signal     implementation in the Linux kernel before 4.3.5 on     powerpc platforms does not check for an MSR with both     the S and T bits set, which allows local users to cause     a denial of service (TM Bad Thing exception and panic)     via a crafted application.(CVE-2015-8844)The     snd_timer_user_params function in sound/core/timer.c in     the Linux kernel through 4.6 does not initialize a     certain data structure, which allows local users to     obtain sensitive information from kernel stack memory     via crafted use of the ALSA timer     interface.(CVE-2016-4569)The tm_reclaim_thread function     in arch/powerpc/kernel/process.c in the Linux kernel     before 4.4.1 on powerpc platforms does not ensure that     TM suspend mode exists before proceeding with a     tm_reclaim call, which allows local users to cause a     denial of service (TM Bad Thing exception and panic)     via a crafted application.(CVE-2015-8845)The VFS     subsystem in the Linux kernel 3.x provides an     incomplete set of requirements for setattr operations     that underspecifies removing extended privilege     attributes, which allows local users to cause a denial     of service (capability stripping) via a failed     invocation of a system call, as demonstrated by using     chown to remove a capability from the ping or Wireshark     dumpcap program.(CVE-2015-1350)The wacom_probe function     in drivers/input/tablet/wacom_sys.c in the Linux kernel     before 3.17 allows physically proximate attackers to     cause a denial of service (NULL pointer dereference and     system crash) via a crafted endpoints value in a USB     device descriptor.(CVE-2016-3139)
