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 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):A buffer overflow was     discovered in tpacket_rcv() function in the Linux     kernel since v4.6-rc1 through v4.13. A number of     socket-related syscalls can be made to set up a     configuration when each packet received by a network     interface can cause writing up to 10 bytes to a kernel     memory outside of a kernel buffer. This can cause     unspecified kernel data corruption effects, including     damage of in-memory and on-disk XFS     data.(CVE-2017-14497)The qmi_wwan_bind function in     driverset/usb/qmi_wwan.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-2017-16650)A race condition flaw was found     in the way the Linux kernel's SCTP implementation     handled sctp_accept() during the processing of     heartbeat timeout events. A remote attacker could use     this flaw to prevent further connections to be accepted     by the SCTP server running on the system, resulting in     a denial of service.(CVE-2015-8767)A race condition     flaw was found in the way the Linux kernel's KVM     subsystem handled PIT (Programmable Interval Timer)     emulation. A guest user who has access to the PIT I/O     ports could use this flaw to crash the     host.(CVE-2014-3611)The Linux kernel is vulnerable to a     memory leak in the     driverset/wireless/mac80211_hwsim.c:hwsim_new_radio_nl(     ) function. An attacker could exploit this to cause a     potential denial of service.(CVE-2018-8087)An integer     underflow flaw was found in the way the Linux kernel's     Stream Control Transmission Protocol (SCTP)     implementation processed certain COOKIE_ECHO packets.
    By sending a specially crafted SCTP packet, a remote     attacker could use this flaw to prevent legitimate     connections to a particular SCTP server socket to be     made.(CVE-2014-4667)The cx231xx_usb_probe function in     drivers/media/usb/cx231xx/cx231xx-cards.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-2017-16536)The     snd_usb_create_streams function in sound/usb/card.c in     the Linux kernel, before 4.13.6, allows local users to     cause a denial of service (out-of-bounds read and     system crash) or possibly have unspecified other impact     via a crafted USB device.(CVE-2017-16529)A flaw was     found in the Linux kernel's random number generator     API. A null pointer dereference in the rngapi_reset     function may result in denial of service, crashing the     system.(CVE-2017-15116)The __netlink_deliver_tap_skb     function in netetlink/af_netlink.c in the Linux kernel,     through 4.14.4, does not restrict observations of     Netlink messages to a single net namespace, when     CONFIG_NLMON is enabled. This allows local users to     obtain sensitive information by leveraging the     CAP_NET_ADMIN capability to sniff an nlmon interface     for all Netlink activity on the     system.(CVE-2017-17449)arch/arm64/kernel/perf_event.c     in the Linux kernel before 4.1 on arm64 platforms     allows local users to gain privileges or cause a denial     of service (invalid pointer dereference) via vectors     involving events that are mishandled during a span of     multiple HW PMUs.(CVE-2015-8955)The aac_compat_ioctl     function in drivers/scsi/aacraid/linit.c in the Linux     kernel before 3.11.8 does not require the CAP_SYS_RAWIO     capability, which allows local users to bypass intended     access restrictions via a crafted ioctl     call.(CVE-2013-6383)Linux kernel before version     4.16-rc7 is vulnerable to a null pointer dereference in     dccp_write_xmit() function in net/dccp/output.c in that     allows a local user to cause a denial of service by a     number of certain crafted system     calls.(CVE-2018-1130)The Linux kernel is vulerable to a     use-after-free flaw when Transformation User     configuration interface(CONFIG_XFRM_USER) compile-time     configuration were enabled. This vulnerability occurs     while closing a xfrm netlink socket in     xfrm_dump_policy_done. A user/process could abuse this     flaw to potentially escalate their privileges on a     system.(CVE-2017-16939)A vulnerability was found in the     Linux kernel in function rds_inc_info_copy of file     net/rds/recv.c. The last field 'flags' of object     'minfo' is not initialized. This can leak data     previously at the flags location to     userspace.(CVE-2016-5244)A flaw was found in the     kernel's ACPI interpreter when it does not flush the     operand cache and causes a kernel stack dump. This     allows local users to obtain sensitive information from     kernel memory and bypass the KASLR protection     mechanism.(CVE-2017-13693)It was found that     kernel/events/core.c in the Linux kernel mishandles     counter grouping, which allows local users to gain     privileges via a crafted application, related to the     perf_pmu_register and perf_event_open     functions.(CVE-2015-9004)The xfs_bmap_extents_to_btree     function in fs/xfs/libxfs/xfs_bmap.c in the Linux     kernel through 4.16.3 allows local users to cause a     denial of service (xfs_bmapi_write NULL pointer     dereference) via a crafted xfs     image.(CVE-2018-10323)The lrw_crypt() function in     'crypto/lrw.c' in the Linux kernel before 4.5 allows     local users to cause a system crash and a denial of     service by the NULL pointer dereference via accept(2)     system call for AF_ALG socket without calling setkey()     first to set a cipher key.(CVE-2015-8970)The IPv6     fragmentation implementation in the Linux kernel does     not consider that the nexthdr field may be associated     with an invalid option, which allows local users to     cause a denial of service (out-of-bounds read and BUG)     or possibly have unspecified other impact via crafted     socket and send system calls. Due to the nature of the     flaw, privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2017-9074)

遠端 Ubuntu 14.04 LTS 主機上安裝的一個套件受到 USN-3360-1 公告中所提及的多個弱點影響。

  - 在 4.7 及更低版本的 Linux 核心中 (用於在 Nexus 5 和 7 (2013) 裝置上的 2016-08-05 之前的 Android 中使用)，net/core/ethtool.c 中的 ethtool_get_wol 函數不會初始化某個資料結構，這允許本機使用者透過特製的應用程式獲取敏感資訊，此問題亦稱 Android 內部錯誤 28803952 和 Qualcomm 內部錯誤 CR570754。(CVE-2014-9900)

  - 在 Linux 核心 4.7 及其之前版本中，kernel/resource.c 中的 ioresources_init 函式 (正如 Nexus 6 和 7 (2013) 裝置上低於 2016-08-05 的 Android 中所使用) 會針對 /proc/iomem 使用弱式權限，這讓本機使用者可以透過讀取此檔案來取得敏感資訊，此問題亦稱 Android 內部錯誤 28814213 和 Qualcomm 內部錯誤 CR786116。注意：在大多數非 Android 內容中，這些權限可能是有意設定的。
    (CVE-2015-8944)

  - 在 arm64 平台上，Linux 核心 4.1 之前版本的  arch/arm64/kernel/perf_event.c 允許本機使用者透過涉及在多個 HW PMU 範圍內錯誤處理之事件的向量，取得權限或造成拒絕服務 (無效的指標解除參照)。(CVE-2015-8955)

  - 在 Linux 核心 4.4 之前版本中，drivers/scsi/sg.c 的 sg_common_write 函式存在重複釋放弱點，這讓本機使用者可以透過在 SG_IO ioctl 呼叫期間卸離裝置，來取得權限或造成拒絕服務 (記憶體損毀和系統當機)。(CVE-2015-8962)

  - 在 Linux 核心 4.4 之前版本中，kernel/events/core.c 中的爭用情形允許本機使用者在 CPU 拔除期間透過錯誤的 swevent 資料結構處理，來取得權限或造成拒絕服務 (釋放後使用)。(CVE-2015-8963)

  - 在 Linux 核心 4.5 之前版本中，drivers/tty/tty_ldisc.c 的 tty_set_termios_ldisc 函式允許本機使用者透過讀取 tty 資料結構，來取得核心記憶體中的敏感資訊。(CVE-2015-8964)

  - 在 Linux 核心 4.4 之前版本中，arch/arm/kernel/sys_oabi-compat.c 允許本機使用者透過 fcntl64 系統呼叫中特製的 (1) F_OFD_GETLK、(2) F_OFD_SETLK 或 (3) F_OFD_SETLKW 命令來取得權限。
    (CVE-2015-8966)

  - 在 Linux 核心 4.0 之前版本中，arch/arm64/kernel/sys.c 允許本機使用者利用寫入存取權，來繞過嚴格的頁面權限保護機制並修改系統呼叫資料表，進而取得特權。(CVE-2015-8967)

  在 4.9 及之前版本的 Linux 核心中，sg 實作在設定 KERNEL_DS 選項的情況下，未正確限制寫入作業，進而允許本機使用者讀取或寫入任意核心記憶體位置，或透過利用對 /dev/sg 裝置的存取，引致拒絕服務 (釋放後使用)，這與 block/bsg.c 和 drivers/scsi/sg.c 有關。注意：此弱點是 CVE-2016-9576 的修正不完整所致。(CVE-2016-10088)

  在 4.11.5 之前的 Linux 核心中，sound/core/timer.c 容易受到 ALSA /dev/snd/timer 驅動程式中的資料爭用影響，導致本機使用者能夠讀取屬於其他使用者的資訊，例如未初始化的記憶體內容讀取和 ioctl 同時發生時可能會洩漏。
    (CVE-2017-1000380)

  - 在 4.10.7 及之前版本的 Linux 核心中，drivers/gpu/drm/vmwgfx/vmwgfx_surface.c 的 vmw_gb_surface_define_ioctl 函式不會驗證特定層級資料，進而允許本機使用者透過 /dev/dri/renderD* 裝置的特製 ioctl 呼叫，引致拒絕服務 (系統懸置)。(CVE-2017-7346)

  - 在 4.10.13 及之前版本的 Linux 核心中，NFSv2 和 NFSv3 伺服器實作缺少對緩衝區結尾的特定檢查，這會讓遠端攻擊者透過特製要求觸髮指標算術錯誤，或可能造成其他不明影響；此問題與 fs/nfsd/nfs3xdr.c 和 fs/nfsd/nfsxdr.c 相關。
    (CVE-2017-7895)

  - 在 Linux 核心 4.10.4 之前版本中，drivers/usb/serial/io_ti.c 的 edge_bulk_in_callback 函式讓本機使用者可以透過使用特製的 USB 裝置 (偽裝為 io_ti USB 系列裝置) 來觸發整數反向溢位，從而自未初始化的核心記憶體取得敏感資訊 (在 dmesg ringbuffer 和 syslog 中)。(CVE-2017-8924)

  - 在 Linux 核心 4.10.4 之前版本中，drivers/usb/serial/omninet.c 的 omninet_open 函式讓本機使用者可以利用參照計數處理不當弱點造成拒絕服務 (tty 耗盡)。
    (CVE-2017-8925)

  - 在 Linux 核心 4.11.4 及之前的所有版本中，drivers/gpu/drm/vmwgfx/vmwgfx_surface.c 中的 vmw_gb_surface_define_ioctl 函式 (可透過 DRM_IOCTL_VMW_GB_SURFACE_CREATE 存取) 會定義 backup_handle 變數，但是未給予初始值。如果嘗試建立 GB 面板，並使用先前配置的 DMA 緩衝區作為備份緩衝區，則不會寫入 backup_handle 變數，並且此變數之後會傳回至使用者空間，這允許本機使用者透過特製的 ioctl 呼叫從未初始化的核心記憶體取得敏感資訊。(CVE-2017-9605)

請注意，Nessus 並未測試這些問題，而是僅依據應用程式自我報告的版本號碼作出判斷。

リモートの Ubuntu 14.04 LTS ホストには、USN-3360-1のアドバイザリに記載された複数の脆弱性の影響を受けるパッケージがインストールされています。

  - 4.7 までの Linux カーネルの net/core/ethtool.c の ethtool_get_wol 関数は、2016 年 8 月 5 日より前に Nexus 5 および 7 (2013) のデバイスで Android で使用されていましたが、特定のデータ構造を初期化しません。このため、ローカルユーザーが細工されたアプリケーションを介して機密情報を取得する可能性があります。これは、Android 内部バグ 28803952 および Qualcomm 内部バグ CR570754 という別名で知られています。(CVE-2014-9900)

  - 4.7 までの Linux カーネルの kernel/resource.c の ioresources_init 関数は、2016 年 8 月 5 日より前に Nexus 6 および 7 (2013) デバイスで使用されていたように、/proc/iomem に対して弱い権限を使用します。このため、ローカルユーザーがこのファイルを読み取ることにより、機密情報を取得する可能性があります。これは、Android 内部バグ 28814213 および Qualcomm 内部バグ CR786116 という別名で知られています。注意:  このアクセス許可は、Android 以外のほとんどのコンテキストで意図的なものである可能性があります。
    (CVE-2015-8944)

  - arm64 プラットフォーム上の 4.1 以前の Linux カーネルの arch/arm64/kernel/perf_event.c では、複数の HW PMUs の範囲内で誤って処理されるイベントに関するベクターを介して、ローカルユーザーが権限を取得したり、サービス拒否 (無効なポインターデリファレンス) を引き起こす可能性があります。(CVE-2015-8955)

  - 4.4 以前の Linux カーネル内の drivers/scsi/sg.c の sg_common_write 関数の二重解放脆弱性により、ローカルユーザーが、SG_IO ioctl 呼び出し中にデバイスを接続解除することで権限を取得したり、サービス拒否 (メモリ破損とシステムクラッシュ) を引き起こしたりする可能性があります。(CVE-2015-8962)

  - 4.4 以前の Linux カーネル内の kernel/events/core.c の競合状態により、ローカルユーザーが、CPU 取り外し操作中に swevent データ構造の不正な処理を利用して権限を取得したり、サービス拒否 (メモリ解放後使用) を引き起こしたりする可能性があります。(CVE-2015-8963)

  - 4.5 以前の Linux カーネル内の drivers/tty/tty_ldisc.c の tty_set_termios_ldisc 関数により、ローカルユーザーが、tty データ構造を読み取ってカーネルメモリから機密情報を取得する可能性がありました。(CVE-2015-8964)

  - 4.4 以前の Linux カーネルの arch/arm/kernel/sys_oabi-compat.c では、ローカルユーザーは、fcntl64 システムコールの細工された (1) F_OFD_GETLK、(2) F_OFD_SETLK、または (3) F_OFD_SETLKW コマンドを介して権限を取得できる可能性があります。
    (CVE-2015-8966)

  - 4.0 以前の Linux カーネルの arch/arm64/kernel/sys.c では、ローカルユーザーが厳格なページ権限保護メカニズムをバイパスし、システムコールテーブルを変更することにより、書き込みアクセスを利用して権限を取得する可能性があります。(CVE-2015-8967)

  -4.9までのLinux カーネルのsg実装は、KERNEL_DSオプションが設定されている場合に書き込み操作を適切に制限しないため、ローカルユーザーが任意のカーネルメモリの場所を読み書きしたり、block/bsg.cとdrivers/scsi/sg.cに関連する/dev/sgデバイスへのアクセスを利用してサービス拒否（メモリ解放後使用（Use After Free））を引き起こす可能性があります。注意:  この脆弱性は、CVE-2016-9576の修正が不完全なために存在します。(CVE-2016-10088)

  - 4.11.5より前の Linux カーネル内の sound/core/timer.c が ALSA/dev/snd/timer ドライバーのデータ競合に対して脆弱なため、ローカルユーザーが、他のユーザーに属している情報を読み取れる可能性があります。つまり、read と ioctl が同時に発生したときに、初期化されていないメモリコンテンツが開示される可能性があります。
    (CVE-2017-1000380)

  -4.10.7までのLinuxカーネルのdrivers/gpu/drm/vmwgfx/vmwgfx_surface.cのvmw_gb_surface_define_ioctl関数が、特定のレベルデータを検証していないため、ローカルユーザーが、/dev/dri/renderD*デバイス用の細工されたioctl呼び出しを介して、サービス拒否（システムハングアップ）を引き起こす可能性があります。（CVE-2017-7346）

  - 4.10.13 までの Linux カーネルの NFSv2 と NFSv3 のサーバーの実装には、バッファの終端に対する特定のチェックがありません。そのため、リモート攻撃者が、細工されたリクエストを介して、ポインター演算エラーをトリガーしたり、その他の詳細不明な影響を与えたりする可能性があります。これは s/nfsd/nfs3xdr.c および fs/nfsd/nfsxdr.c に関連しています。
    (CVE-2017-7895)

  - 4.10.4以前のLinuxカーネル内のdrivers/usb/serial/io_ti.cにあるedge_bulk_in_callback関数により、ローカルユーザーが細工されたUSBデバイスを使用して（io_ti USBシリアルデバイスのふりをして）整数アンダーフローを発生させることで、初期化されていないカーネルメモリから（dmesgのリングバッファとsyslogで）機密情報を入手する可能性があります。（CVE-2017-8924）

  - 4.10.4以前のLinuxカーネル内のdrivers/usb/serial/omninet.cのomninet_open関数により、 ローカルユーザーが参照カウントの不適切な処理を活用することで、サービス拒否（tty枯渇）を引き起こす可能性があります。
    (CVE-2017-8925)

  4.11.4 までの Linux カーネルでは、drivers/gpu/drm/vmwgfx/vmwgfx_surface.c の vmw_gb_surface_define_ioctl 関数 (DRM_IOCTL_VMW_GB_SURFACE_CREATE を介してアクセス可能) が backup_handle 変数を定義しますが、初期値は与えません。バックアップバッファとして使用するために以前に割り当てられたDMAバッファでGBサーフェスを作成しようとすると、backup_handle変数は書き込まれず、後でユーザー空間に戻されます。これによりローカルユーザーが、細工されたioctl呼び出しを介して、初期化されていないカーネルメモリから機密情報を取得できるようになります。（CVE-2017-9605）

Nessus はこれらの問題をテストしておらず、代わりにアプリケーションが自己報告するバージョン番号にのみ依存していることに注意してください。
