The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.

The 4.17.4 stable kernel update contains a number of important updates across the tree.

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

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

Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - 在 Linux 核心 4.17.2 及之前版本中發現一個問題。kernel/trace/trace_events_filter.c 中的篩選剖析可在沒有篩選的情況下遭到呼叫N=0 的情況是其預期至少已讀取一行因而會使 N-1 索引無效。這可讓攻擊者透過特製的 perf_event_open 和 mmap 系統呼叫造成拒絕服務 (slab 超出邊界寫入) 或可能造成其他不明影響。 (CVE-2018-12714)

請注意，Nessus 依賴供應商報告的套件存在。

Linux/Unix ホストには、ベンダーが提供するパッチが利用できない脆弱性の影響を受ける複数のパッケージがインストールされています。

  - 4.17.2 までの Linux カーネルで問題が発見されました。kernel/trace/trace_events_filter.cのフィルター解析は、フィルターなしで呼び出される可能性があります。これは、少なくとも1つの行が読み取られることが期待される場合のN=0の場合であるため、N-1インデックスを無効にしてしまいます。これにより、攻撃者はサービス拒否スラブ領域外書き込みを引き起こすことができ、細工された perf_event_open および mmap システムコールを介して他の詳細不明の影響を及ぼす可能性があります。CVE-2018-12714

Nessus は、ベンダーによって報告されたパッケージの存在に依存していることに注意してください。

Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。
