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

  - A flaw was found in the USB-MIDI Linux kernel driver: a     double-free error could be triggered for the 'umidi'     object. An attacker with physical access to the system     could use this flaw to escalate their     privileges.(CVE-2016-2384)

  - A vulnerability was found in Linux kernel. There is an     information leak in file 'sound/core/timer.c' of the     latest mainline Linux kernel, the stack object 'tread'     has a total size of 32 bytes. It contains a 8-bytes     padding, which is not initialized but sent to user via     copy_to_user(), resulting a kernel leak.(CVE-2016-4569)

  - 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 tcp_v6_syn_recv_sock function in     net/ipv6/tcp_ipv6.c in the Linux kernel through 4.14.11     allows attackers to cause a denial of service (slab     out-of-bounds write) or possibly have unspecified other     impact via vectors involving TLS.(CVE-2018-5703)

  - An issue was discovered in the fd_locked_ioctl function     in drivers/block/floppy.c in the Linux kernel. The     floppy driver will copy a kernel pointer to user memory     in response to the FDGETPRM ioctl. An attacker can send     the FDGETPRM ioctl and use the obtained kernel pointer     to discover the location of kernel code and data and     bypass kernel security protections such as     KASLR.(CVE-2018-7755)

  - The usbnet_generic_cdc_bind function in     drivers/net/usb/cdc_ether.c in the Linux kernel through     4.13.11 allows local users to cause a denial of service     (divide-by-zero error and system crash) or possibly     have unspecified other impact via a crafted USB     device.(CVE-2017-16649)

  - Heap-based buffer overflow in the wcnss_wlan_write     function in drivers/net/wireless/wcnss/wcnss_wlan.c in     the wcnss_wlan device driver for the Linux kernel 3.x,     as used in Qualcomm Innovation Center (QuIC) Android     contributions for MSM devices and other products,     allows attackers to cause a denial of service or     possibly have unspecified other impact by writing to     /dev/wcnss_wlan with an unexpected amount of     data.(CVE-2016-5342)

  - drivers/media/usb/dvb-usb/dib0700_devices.c in the     Linux kernel through 4.13.11 allows local users to     cause a denial of service (BUG and system crash) or     possibly have unspecified other impact via a crafted     USB device.(CVE-2017-16646)

  - A flaw was found in the TIPC networking subsystem which     could allow for memory corruption and possible     privilege escalation. The flaw involves a system with     an unusually low MTU (60) on networking devices     configured as bearers for the TIPC protocol. An     attacker could create a packet which will overwrite     memory outside of allocated space and allow for     privilege escalation.(CVE-2016-8632)

  - An issue was discovered in the XFS filesystem in     fs/xfs/libxfs/xfs_inode_buf.c in the Linux kernel. A     denial of service due to the NULL pointer dereference     can occur for a corrupted xfs image upon encountering     an inode that is in extent format, but has more extents     than fit in the inode fork.(CVE-2018-13095)

  - Linux kernel built with the KVM visualization support     (CONFIG_KVM), with nested visualization (nVMX) feature     enabled (nested=1), is vulnerable to a crash due to     disabled external interrupts. As L2 guest could access     (r/w) hardware CR8 register of the host(L0). In a     nested visualization setup, L2 guest user could use     this flaw to potentially crash the host(L0) resulting     in DoS.(CVE-2017-12154)

  - The do_double_fault function in arch/x86/kernel/traps.c     in the Linux kernel through 3.17.4 does not properly     handle faults associated with the Stack Segment (SS)     segment register, which allows local users to cause a     denial of service (panic) via a modify_ldt system call,     as demonstrated by sigreturn_32 in the     linux-clock-tests test suite.(CVE-2014-9090)

  - A race condition flaw was found in the way the Linux     kernel's mac80211 subsystem implementation handled     synchronization between TX and STA wake-up code paths.
    A remote attacker could use this flaw to crash the     system.(CVE-2014-2706)

  - The snd_seq_ioctl_remove_events function in     sound/core/seq/seq_clientmgr.c in the Linux kernel     before 4.4.1 does not verify FIFO assignment before     proceeding with FIFO clearing, which allows local users     to cause a denial of service (NULL pointer dereference     and OOPS) via a crafted ioctl call.(CVE-2016-2543)

  - 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)

  - An integer overflow flaw was found in the Linux     kernel's create_elf_tables() function. An unprivileged     local user with access to SUID (or otherwise     privileged) binary could use this flaw to escalate     their privileges on the system.(CVE-2018-14634)

  - A use-after-free flaw was found in the Netlink     functionality of the Linux kernel networking subsystem.
    Due to the insufficient cleanup in the mq_notify     function, a local attacker could potentially use this     flaw to escalate their privileges on the     system.(CVE-2017-11176)

  - Array index error in the aio_read_events_ring function     in fs/aio.c in the Linux kernel through 3.15.1 allows     local users to obtain sensitive information from kernel     memory via a large head value.(CVE-2014-0206)

  - arch/arm/kernel/sys_oabi-compat.c in the Linux kernel     before 4.4 allows local users to gain privileges via a     crafted (1) F_OFD_GETLK, (2) F_OFD_SETLK, or (3)     F_OFD_SETLKW command in an fcntl64 system     call.(CVE-2015-8966)

  - An issue was discovered in the Linux kernel through     4.17.2. The filter parsing in     kernel/trace/trace_events_filter.c could be called with     no filter, which is an N=0 case when it expected at     least one line to have been read, thus making the N-1     index invalid. This allows attackers to cause a denial     of service (slab out-of-bounds write) or possibly have     unspecified other impact via crafted perf_event_open     and mmap system calls.(CVE-2018-12714)

The SUSE Linux Enterprise 15 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

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-2018-14613: Prevent invalid pointer dereference in io_ctl_map_page() when mounting and operating a crafted btrfs image, caused by a lack of block group item validation in check_leaf_item (bsc#1102896).

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-2018-13093: 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-2018-13094: Prevent OOPS that may have occured for a corrupted xfs image after xfs_da_shrink_inode() is called with a NULL bp (bnc#1100000)

CVE-2018-13095: Prevent denial of service (memory corruption and BUG) that could have occurred for a corrupted xfs image upon encountering an inode that is in extent format, but has more extents than fit in the inode fork (bnc#1099999)

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

CVE-2018-6554: 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-2018-1129: A flaw was found in the way signature calculation was handled by cephx authentication protocol. An attacker having access to ceph cluster network who is able to alter the message payload was able to bypass signature checks done by cephx protocol (bnc#1096748)

CVE-2018-1128: It was found that cephx authentication protocol did not verify ceph clients correctly and was vulnerable to replay attack. Any attacker having access to ceph cluster network who is able to sniff packets on network can use this vulnerability to authenticate with ceph service and perform actions allowed by ceph service (bnc#1096748)

CVE-2018-10938: A crafted network packet sent remotely by an attacker forced the kernel to enter an infinite loop in the cipso_v4_optptr() function leading to a denial-of-service (bnc#1106016)

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

CVE-2018-10878: A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bounds write and a denial of service or unspecified other impact is possible by mounting and operating a crafted ext4 filesystem image. (bnc#1099813)

CVE-2018-10879: A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause a use-after-free in ext4_xattr_set_entry function and a denial of service or unspecified other impact may occur by renaming a file in a crafted ext4 filesystem image. (bnc#1099844)

CVE-2018-10880: Linux kernel is vulnerable to a 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 use this to cause a system crash and a denial of service. (bnc#1099845)

CVE-2018-10881: A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause 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.
(bnc#1099864)

CVE-2018-10882: A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bound write in in fs/jbd2/transaction.c code, a denial of service, and a system crash by unmounting a crafted ext4 filesystem image. (bnc#1099849)

(bnc#1099863)

CVE-2018-10902: It was found that the raw midi kernel driver did not protect against concurrent access which leads to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status() which are part of snd_rawmidi_ioctl() handler in rawmidi.c file. A malicious local attacker could possibly use this for privilege escalation (bnc#1105322).

CVE-2018-10938: A crafted network packet sent remotely by an attacker may force the kernel to enter an infinite loop in the cipso_v4_optptr() function in net/ipv4/cipso_ipv4.c leading to a denial-of-service. A certain non-default configuration of LSM (Linux Security Module) and NetLabel should be set up on a system before an attacker could leverage this flaw (bnc#1106016).

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

CVE-2018-13095: A denial of service (memory corruption and BUG) can occur for a corrupted xfs image upon encountering an inode that is in extent format, but has more extents than fit in the inode fork (bnc#1099999).

CVE-2018-14617: 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 (bnc#1102870).

CVE-2018-14678: The xen_failsafe_callback entry point in arch/x86/entry/entry_64.S did not properly maintain RBX, which allowed local users to cause a denial of service (uninitialized memory usage and system crash). Within Xen, 64-bit x86 PV Linux guest OS users can trigger a guest OS crash or possibly gain privileges (bnc#1102715).

CVE-2018-15572: The spectre_v2_select_mitigation function in arch/x86/kernel/cpu/bugs.c did not always fill RSB upon a context switch, which made it easier for attackers to conduct userspace-userspace spectreRSB attacks (bnc#1102517 bnc#1105296).

CVE-2018-15594: arch/x86/kernel/paravirt.c mishandled certain indirect calls, which made it easier for attackers to conduct Spectre-v2 attacks against paravirtual guests (bnc#1105348).

CVE-2018-16276: Local attackers could use user access read/writes with incorrect bounds checking in the yurex USB driver to crash the kernel or potentially escalate privileges (bnc#1106095).

CVE-2018-16658: An information leak in cdrom_ioctl_drive_status in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 (bnc#1107689).

CVE-2018-17182: The vmacache_flush_all function in mm/vmacache.c mishandled sequence number overflows. An attacker can trigger a use-after-free (and possibly gain privileges) via certain thread creation, map, unmap, invalidation, and dereference operations (bnc#1108399).

CVE-2018-6554: Memory leak in the irda_bind function in net/irda/af_irda.c and later in drivers/staging/irda/net/af_irda.c allowed local users to cause a denial of service (memory consumption) by repeatedly binding an AF_IRDA socket (bnc#1106509).

CVE-2018-6555: The irda_setsockopt function in net/irda/af_irda.c and later in drivers/staging/irda/net/af_irda.c 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-2018-7757: Memory leak in the sas_smp_get_phy_events function in drivers/scsi/libsas/sas_expander.c allowed local users to cause a denial of service (memory consumption) via many read accesses to files in the /sys/class/sas_phy directory, as demonstrated by the /sys/class/sas_phy/phy-1:0:12/invalid_dword_count file (bnc#1084536).

CVE-2018-9363: A buffer overflow in bluetooth HID report processing could be used by malicious bluetooth devices to crash the kernel or potentially execute code (bnc#1105292). The following security bugs were fixed :

CVE-2018-7480: The blkcg_init_queue function in block/blk-cgroup.c allowed local users to cause a denial of service (double free) or possibly have unspecified other impact by triggering a creation failure (bnc#1082863).
