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。

  - Linux 核心 3.x 中的 TCP 堆疊在快速網路連線的情況下，並未正確實作 SYN cookie 保護機制，進而允許遠端攻擊者傳送許多 TCP SYN 封包來造成拒絕服務 (CPU 消耗)，如針對 CentOS Linux 7 中的 kernel-3.10.0 套件發動的攻擊即為一例。注意：第三方無法辨別 GitHub Engineering 的發現與 Trigemini.c 攻擊程式碼之間的任何關係。 (CVE-2017-5972)

請注意，Nessus 依賴供應商報告的套件存在。

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。

  - Linux 内核中的 TCP 堆栈 3.x 没有为快速网络连接正确实现 SYN Cookie 保护机制，从而允许远程攻击者通过发送许多 TCP SYN 数据包造成拒绝服务（CPU 消耗），因为已由针对 CentOS Linux 7 中的 kernel-3.10.0 程序包的攻击证实。注意：第三方无法辨别 GitHub Engineering 调查结果与 Trigemini.c 攻击代码之间的任何关系。 (CVE-2017-5972)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

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。

  - Linux カーネルの TCP スタック 3.x は、高速ネットワーク接続の場合に備えて、SYN クッキー保護メカニズムを適切に実装していません。これにより、リモートの攻撃者は、は、CentOS Linux 7 の kernel-3.10.0 パッケージに対する攻撃によって実証されています。注：サードパーティは、GitHub Engineering の調査結果と Trigemini.c 攻撃コードとの関係を特定できていません。 （CVE-2017-5972）

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。

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

  - The TCP stack in the Linux kernel 3.x does not properly implement a SYN cookie protection mechanism for     the case of a fast network connection, which allows remote attackers to cause a denial of service (CPU     consumption) by sending many TCP SYN packets, as demonstrated by an attack against the kernel-3.10.0     package in CentOS Linux 7. NOTE: third parties have been unable to discern any relationship between the     GitHub Engineering finding and the Trigemini.c attack code. (CVE-2017-5972)

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

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 :

  - The x25_negotiate_facilities function in     net/x25/x25_facilities.c in the Linux kernel before     4.5.5 does not properly initialize a certain data     structure, which allows attackers to obtain sensitive     information from kernel stack memory via an X.25 Call     Request.(CVE-2016-4580i1/4%0

  - A flaw was found in the Linux kernel's implementation     of seq_file where a local attacker could manipulate     memory in the put() function pointer. This could lead     to memory corruption and possible privileged     escalation.(CVE-2016-7910i1/4%0

  - A flaw was found in the way the Linux kernel's     netfilter subsystem handled generic protocol tracking.
    As demonstrated in the Stream Control Transmission     Protocol (SCTP) case, a remote attacker could use this     flaw to bypass intended iptables rule restrictions when     the associated connection tracking module was not     loaded on the system.(CVE-2014-8160i1/4%0

  - The get_endpoints function in     drivers/usb/misc/usbtest.c in the Linux kernel through     4.13.11 allows local users to cause a denial of service     (NULL pointer dereference and system crash) or possibly     have unspecified other impact via a crafted USB     device.(CVE-2017-16532i1/4%0

  - An integer overflow flaw was found in the way the Linux     kernel's Advanced Linux Sound Architecture (ALSA)     implementation handled user controls. A local,     privileged user could use this flaw to crash the     system.(CVE-2014-4656i1/4%0

  - The sr_do_ioctl function in drivers/scsi/sr_ioctl.c in     the Linux kernel through 4.16.12 allows local users to     cause a denial of service (stack-based buffer overflow)     or possibly have unspecified other impact because sense     buffers have different sizes at the CDROM layer and the     SCSI layer.(CVE-2018-11506i1/4%0

  - A race condition flaw was found in the way the Linux     kernel's SCTP implementation handled Address     Configuration lists when performing Address     Configuration Change (ASCONF). A local attacker could     use this flaw to crash the system via a race condition     triggered by setting certain ASCONF options on a     socket.(CVE-2015-3212i1/4%0

  - A symlink size validation was missing in Linux kernels     built with UDF file system (CONFIG_UDF_FS) support,     allowing the corruption of kernel memory. An attacker     able to mount a corrupted/malicious UDF file system     image could cause the kernel to crash.(CVE-2014-9729i1/4%0

  - The Linux kernel before version 4.11 is vulnerable to a     NULL pointer dereference in     fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() that allows an     attacker controlling a CIFS server to kernel panic a     client that has this server mounted, because an empty     TargetInfo field in an NTLMSSP setup negotiation     response is mishandled during session     recovery.(CVE-2018-1066i1/4%0

  - drivers/hid/hid-sensor-hub.c in the Human Interface     Device (HID) subsystem in the Linux kernel through     3.11, when CONFIG_HID_SENSOR_HUB is enabled, allows     physically proximate attackers to obtain sensitive     information from kernel memory via a crafted     device.(CVE-2013-2898i1/4%0

  - An issue was discovered in the Linux kernel's F2FS     filesystem code. A buffer overflow in     truncate_inline_inode() in the fs/f2fs/inline.c     function, when umounting a crafted f2fs image, can     occur because a length value may be     negative.(CVE-2018-14615i1/4%0

  - The help function in net/netfilter/nf_nat_irc.c in the     Linux kernel before 3.12.8 allows remote attackers to     obtain sensitive information from kernel memory by     establishing an IRC DCC session in which incorrect     packet data is transmitted during use of the NAT mangle     feature.(CVE-2014-1690i1/4%0

  - It was found that the Linux kernel's keys subsystem did     not correctly garbage collect uninstantiated keyrings.
    A local attacker could use this flaw to crash the     system or, potentially, escalate their privileges on     the system.(CVE-2015-7872i1/4%0

  - The TCP stack in the Linux kernel 3.x does not properly     implement a SYN cookie protection mechanism for the     case of a fast network connection, which allows remote     attackers to cause a denial of service (CPU     consumption) by sending many TCP SYN packets, as     demonstrated by an attack against the kernel-3.10.0     package in CentOS Linux 7. NOTE: third parties have     been unable to discern any relationship between the     GitHub Engineering finding and the Trigemini.c attack     code.(CVE-2017-5972i1/4%0

  - The xfrm_migrate() function in the     net/xfrm/xfrm_policy.c file in the Linux kernel built     with CONFIG_XFRM_MIGRATE does not verify if the dir     parameter is less than XFRM_POLICY_MAX. This allows a     local attacker to cause a denial of service     (out-of-bounds access) or possibly have unspecified     other impact by sending a XFRM_MSG_MIGRATE netlink     message. This flaw is present in the Linux kernel since     an introduction of XFRM_MSG_MIGRATE in 2.6.21-rc1, up     to 4.13-rc3.(CVE-2017-11600i1/4%0

  - A use-after-free flaw was found in the Linux kernel     which enables a race condition in the L2TPv3 IP     Encapsulation feature. A local user could use this flaw     to escalate their privileges or crash the     system.(CVE-2016-10200i1/4%0

  - A flaw was found in the way the Linux kernel's VFS     subsystem handled file system locks. A local,     unprivileged user could use this flaw to trigger a     deadlock in the kernel, causing a denial of service on     the system.(CVE-2014-8559i1/4%0

  - Multiple buffer overflows in     drivers/staging/wlags49_h2/wl_priv.c in the Linux     kernel before 3.12 allow local users to cause a denial     of service or possibly have unspecified other impact by     leveraging the CAP_NET_ADMIN capability and providing a     long station-name string, related to the (1)     wvlan_uil_put_info and (2) wvlan_set_station_nickname     functions.(CVE-2013-4514i1/4%0

  - The udl_fb_mmap function in     drivers/gpu/drm/udl/udl_fb.c at the Linux kernel     version 3.4 and up to and including 4.15 has an     integer-overflow vulnerability allowing local users     with access to the udldrmfb driver to obtain full read     and write permissions on kernel physical pages,     resulting in a code execution in kernel     space.(CVE-2018-8781i1/4%0

  - A flaw was discovered in the Linux kernel where issuing     certain ioctl() -s commands to the '/dev/ppp' device     file could lead to a NULL pointer dereference. A     privileged user could use this flaw to cause a kernel     crash and denial of service.(CVE-2015-7799i1/4%0
