The tipc_msg_build function in net/tipc/msg.c in the Linux kernel through 4.8.11 does not validate the relationship between the minimum fragment length and the maximum packet size, which allows local users to gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN capability.

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 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-2016-2384i1/4%0

  - 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     aEURoetreadaEUR 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-2016-4569i1/4%0

  - 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-2013-7281i1/4%0

  - 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-2018-5703i1/4%0

  - 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-2018-7755i1/4%0

  - 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-2017-16649i1/4%0

  - 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-2016-5342i1/4%0

  - 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-2017-16646i1/4%0

  - 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-2016-8632i1/4%0

  - 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-2018-13095i1/4%0

  - 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-2017-12154i1/4%0

  - 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-2014-9090i1/4%0

  - 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-2014-2706i1/4%0

  - 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-2016-2543i1/4%0

  - 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-2016-2187i1/4%0

  - 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-2018-14634i1/4%0

  - 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-2017-11176i1/4%0

  - 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-2014-0206i1/4%0

  - 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-2015-8966i1/4%0

  - 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-2018-12714i1/4%0

The SUSE Linux Enterprise 12 SP2 kernel was updated to receive critical security fixes. The following security bugs were fixed :

  - CVE-2016-8655: A race condition in the af_packet     packet_set_ring function could be used by local     attackers to crash the kernel or gain privileges     (bsc#1012754).

  - CVE-2016-8632: The tipc_msg_build function in     net/tipc/msg.c in the Linux kernel did not validate the     relationship between the minimum fragment length and the     maximum packet size, which allowed local users to gain     privileges or cause a denial of service (heap-based     buffer overflow) by leveraging the CAP_NET_ADMIN     capability (bnc#1008831).

  - CVE-2016-9555: The sctp_sf_ootb function in     net/sctp/sm_statefuns.c in the Linux kernel lacks     chunk-length checking for the first chunk, which allowed     remote attackers to cause a denial of service     (out-of-bounds slab access) or possibly have unspecified     other impact via crafted SCTP data (bnc#1011685).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
