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 :

  - drivers/soc/qcom/qdsp6v2/voice_svc.c in the QDSP6v2     Voice Service 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 (memory     corruption) or possibly have unspecified other impact     via a write request, as demonstrated by a     voice_svc_send_req buffer overflow.(CVE-2016-5343i1/4%0

  - A use-after-free 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-2014-4655i1/4%0

  - Race condition in the handle_to_path function in     fs/fhandle.c in the Linux kernel through 3.19.1 allows     local users to bypass intended size restrictions and     trigger read operations on additional memory locations     by changing the handle_bytes value of a file handle     during the execution of this function.(CVE-2015-1420i1/4%0

  - A flaw was found in the way the Linux kernel's keys     subsystem handled the termination condition in the     associative array garbage collection functionality. A     local, unprivileged user could use this flaw to crash     the system.(CVE-2014-3631i1/4%0

  - A flaw was found in the ext4 subsystem. This     vulnerability is a use after free vulnerability was     found in __ext4_journal_stop(). Attackers could abuse     this to allow any code which attempts to deal with the     journal failure to be mishandled or not fail at all.
    This could lead to data corruption or     crashes.(CVE-2015-8961i1/4%0

  - Buffer overflow in the oz_cdev_write function in     drivers/staging/ozwpan/ozcdev.c in the Linux kernel     before 3.12 allows local users to cause a denial of     service or possibly have unspecified other impact via a     crafted write operation.(CVE-2013-4513i1/4%0

  - The nfnetlink_rcv_batch() function in     'net/netfilter/nfnetlink.c' in the Linux kernel before     4.5 does not check whether a batch message's length     field is large enough, which allows local users to     obtain sensitive information from kernel memory or     cause a denial of service (infinite loop or     out-of-bounds read) by leveraging the CAP_NET_ADMIN     capability.(CVE-2016-7917i1/4%0

  - Array index error in the kvm_vm_ioctl_create_vcpu     function in virt/kvm/kvm_main.c in the KVM subsystem in     the Linux kernel through 3.12.5 allows local users to     gain privileges via a large id value.(CVE-2013-4587i1/4%0

  - A leak of information was possible when issuing a     netlink command of the stack memory area leading up to     this function call. An attacker could use this to     determine stack information for use in a later     exploit.(CVE-2016-5243i1/4%0

  - An issue was discovered in the Linux kernel in the F2FS     filesystem code. A NULL pointer dereference in     fscrypt_do_page_crypto() in the fs/crypto/crypto.c     function can occur when operating on a file on a     corrupted f2fs image.(CVE-2018-14616i1/4%0

  - An out-of-bounds flaw was found in the kernel, where     the sco_sock_bind() function (bluetooth/sco) did not     check the length of its sockaddr parameter. As a     result, more kernel memory was copied out than     required, leaking information from the kernel stack     (including kernel addresses). A local user could     exploit this flaw to bypass kernel ASLR or leak other     information.(CVE-2015-8575i1/4%0

  - A denial of service vulnerability was found in the     WhiteHEAT USB Serial Driver (whiteheat_attach function     in drivers/usb/serial/whiteheat.c). In the driver, the     COMMAND_PORT variable was hard coded and set to 4 (5th     element). The driver assumed that the number of ports     would always be 5 and used port number 5 as the command     port. However, when using a USB device in which the     number of ports was set to a number less than 5 (for     example, 3), the driver triggered a kernel NULL-pointer     dereference. A non-privileged attacker could use this     flaw to panic the host.(CVE-2015-5257i1/4%0

  - The LLC subsystem in the Linux kernel does not ensure     that a certain destructor exists in required     circumstances, which allows local users to cause a     denial of service (BUG_ON) or possibly have unspecified     other impact via crafted system calls.(CVE-2017-6345i1/4%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 aEURoer1aEUR     has a total size of 32 bytes. Its field aEURoeeventaEUR and     aEURoevalaEUR both contain 4 bytes padding. These 8 bytes     padding bytes are sent to user without being     initialized.(CVE-2016-4578i1/4%0

  - An information leak flaw was found in the way the Linux     kernel changed certain segment registers and     thread-local storage (TLS) during a context switch. A     local, unprivileged user could use this flaw to leak     the user space TLS base address of an arbitrary     process.(CVE-2014-9419i1/4%0

  - A flaw was found in the way memory was being allocated     on the stack for user space binaries. If heap (or     different memory region) and stack memory regions were     adjacent to each other, an attacker could use this flaw     to jump over the stack guard gap, cause controlled     memory corruption on process stack or the adjacent     memory region, and thus increase their privileges on     the system. This is a kernel-side mitigation which     increases the stack guard gap size from one page to 1     MiB to make successful exploitation of this issue more     difficult.(CVE-2017-1000364i1/4%0

  - A flaw was found in the Linux kernel's handling of     clearing SELinux attributes on /proc/pid/attr files. An     empty (null) write to this file can crash the system by     causing the system to attempt to access unmapped kernel     memory.(CVE-2017-2618i1/4%0

  - A use-after-free vulnerability was found in ALSA pcm     layer, which allows local users to cause a denial of     service, memory corruption, or possibly other     unspecified impact. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2016-9794i1/4%0

  - A flaw was found in the way the Linux kernel's floppy     driver handled user space provided data in certain     error code paths while processing FDRAWCMD IOCTL     commands. A local user with write access to /dev/fdX     could use this flaw to free (using the kfree()     function) arbitrary kernel memory. (CVE-2014-1737,     Important)t was found that the Linux kernel's floppy     driver leaked internal kernel memory addresses to user     space during the processing of the FDRAWCMD IOCTL     command. A local user with write access to /dev/fdX     could use this flaw to obtain information about the     kernel heap arrangement. (CVE-2014-1738, Low)Note: A     local user with write access to /dev/fdX could use     these two flaws (CVE-2014-1737 in combination with     CVE-2014-1738) to escalate their privileges on the     system.(CVE-2014-1737i1/4%0

  - An out-of-bounds memory access flaw was found in the     Linux kernel's aiptek USB tablet driver (aiptek_probe()     function in drivers/input/tablet/aiptek.c). The driver     assumed that the interface always had at least one     endpoint. By using a specially crafted USB device with     no endpoints on one of its interfaces, an unprivileged     user with physical access to the system could trigger a     kernel NULL pointer dereference, causing the system to     panic.(CVE-2015-7515i1/4%0

(CVE-2014-0181, Moderate)

    * It was found that the try_to_unmap_cluster() function in the Linux     kernel's Memory Managment subsystem did not properly handle page locking in     certain cases, which could potentially trigger the BUG_ON() macro in the     mlock_vma_page() function. A local, unprivileged user could use this flaw     to crash the system. (CVE-2014-3122, Moderate)

    * A flaw was found in the way the Linux kernel's kvm_iommu_map_pages()     function handled IOMMU mapping failures. A privileged user in a guest with     an assigned host device could use this flaw to crash the host.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Multiple vulnerabilities has been found and corrected in the Linux kernel :

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-2013-4514).

Use-after-free vulnerability in the skb_segment function in net/core/skbuff.c in the Linux kernel through 3.13.6 allows attackers to obtain sensitive information from kernel memory by leveraging the absence of a certain orphaning operation (CVE-2014-0131).

The rd_build_device_space function in drivers/target/target_core_rd.c in the Linux kernel before 3.14 does not properly initialize a certain data structure, which allows local users to obtain sensitive information from ramdisk_mcp memory by leveraging access to a SCSI initiator (CVE-2014-4027).

Multiple integer overflows in the lzo1x_decompress_safe function in lib/lzo/lzo1x_decompress_safe.c in the LZO decompressor in the Linux kernel before 3.15.2 allow context-dependent attackers to cause a denial of service (memory corruption) via a crafted Literal Run (CVE-2014-4608).

Race condition in the tlv handler functionality in the snd_ctl_elem_user_tlv function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 allows local users to obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access (CVE-2014-4652).

sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not ensure possession of a read/write lock, which allows local users to cause a denial of service (use-after-free) and obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access (CVE-2014-4653).

The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not check authorization for SNDRV_CTL_IOCTL_ELEM_REPLACE commands, which allows local users to remove kernel controls and cause a denial of service (use-after-free and system crash) by leveraging /dev/snd/controlCX access for an ioctl call (CVE-2014-4654).

The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not properly maintain the user_ctl_count value, which allows local users to cause a denial of service (integer overflow and limit bypass) by leveraging /dev/snd/controlCX access for a large number of SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl calls (CVE-2014-4655).

Multiple integer overflows in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 allow local users to cause a denial of service by leveraging /dev/snd/controlCX access, related to (1) index values in the snd_ctl_add function and (2) numid values in the snd_ctl_remove_numid_conflict function (CVE-2014-4656).

The sctp_association_free function in net/sctp/associola.c in the Linux kernel before 3.15.2 does not properly manage a certain backlog value, which allows remote attackers to cause a denial of service (socket outage) via a crafted SCTP packet (CVE-2014-4667).

The Linux kernel before 3.15.4 on Intel processors does not properly restrict use of a non-canonical value for the saved RIP address in the case of a system call that does not use IRET, which allows local users to leverage a race condition and gain privileges, or cause a denial of service (double fault), via a crafted application that makes ptrace and fork system calls (CVE-2014-4699).

The PPPoL2TP feature in net/l2tp/l2tp_ppp.c in the Linux kernel through 3.15.6 allows local users to gain privileges by leveraging data-structure differences between an l2tp socket and an inet socket (CVE-2014-4943).

The SUSE Linux Enterprise Server 11 SP2 LTSS received a roll up update to fix several security and non-security issues.

The following security issues have been fixed :

  - CVE-2014-0055: The get_rx_bufs function in     drivers/vhost/net.c in the vhost-net subsystem in the     Linux kernel package before 2.6.32-431.11.2 on Red Hat     Enterprise Linux (RHEL) 6 does not properly handle     vhost_get_vq_desc errors, which allows guest OS users to     cause a denial of service (host OS crash) via     unspecified vectors. (bnc#870173)

  - CVE-2014-0077: drivers/vhost/net.c in the Linux kernel     before 3.13.10, when mergeable buffers are disabled,     does not properly validate packet lengths, which allows     guest OS users to cause a denial of service (memory     corruption and host OS crash) or possibly gain     privileges on the host OS via crafted packets, related     to the handle_rx and get_rx_bufs functions. (bnc#870576)

  - CVE-2014-1739: The media_device_enum_entities function     in drivers/media/media-device.c in the Linux kernel     before 3.14.6 does not initialize a certain data     structure, which allows local users to obtain sensitive     information from kernel memory by leveraging /dev/media0     read access for a MEDIA_IOC_ENUM_ENTITIES ioctl call.
    (bnc#882804)

  - CVE-2014-2706: Race condition in the mac80211 subsystem     in the Linux kernel before 3.13.7 allows remote     attackers to cause a denial of service (system crash)     via network traffic that improperly interacts with the     WLAN_STA_PS_STA state (aka power-save mode), related to     sta_info.c and tx.c. (bnc#871797)

  - CVE-2014-2851: Integer overflow in the ping_init_sock     function in net/ipv4/ping.c in the Linux kernel through     3.14.1 allows local users to cause a denial of service     (use-after-free and system crash) or possibly gain     privileges via a crafted application that leverages an     improperly managed reference counter. (bnc#873374)

  - CVE-2014-3144: The (1) BPF_S_ANC_NLATTR and (2)     BPF_S_ANC_NLATTR_NEST extension implementations in the     sk_run_filter function in net/core/filter.c in the Linux     kernel through 3.14.3 do not check whether a certain     length value is sufficiently large, which allows local     users to cause a denial of service (integer underflow     and system crash) via crafted BPF instructions. NOTE:
    the affected code was moved to the __skb_get_nlattr and
    __skb_get_nlattr_nest functions before the vulnerability     was announced. (bnc#877257)

  - CVE-2014-3145: The BPF_S_ANC_NLATTR_NEST extension     implementation in the sk_run_filter function in     net/core/filter.c in the Linux kernel through 3.14.3     uses the reverse order in a certain subtraction, which     allows local users to cause a denial of service     (over-read and system crash) via crafted BPF     instructions. NOTE: the affected code was moved to the
    __skb_get_nlattr_nest function before the vulnerability     was announced. (bnc#877257)

  - CVE-2014-3917: kernel/auditsc.c in the Linux kernel     through 3.14.5, when CONFIG_AUDITSYSCALL is enabled with     certain syscall rules, allows local users to obtain     potentially sensitive single-bit values from kernel     memory or cause a denial of service (OOPS) via a large     value of a syscall number. (bnc#880484)

  - CVE-2014-4508: arch/x86/kernel/entry_32.S in the Linux     kernel through 3.15.1 on 32-bit x86 platforms, when     syscall auditing is enabled and the sep CPU feature flag     is set, allows local users to cause a denial of service     (OOPS and system crash) via an invalid syscall number,     as demonstrated by number 1000. (bnc#883724)

  - CVE-2014-4652: Race condition in the tlv handler     functionality in the snd_ctl_elem_user_tlv function in     sound/core/control.c in the ALSA control implementation     in the Linux kernel before 3.15.2 allows local users to     obtain sensitive information from kernel memory by     leveraging /dev/snd/controlCX access. (bnc#883795)

  - CVE-2014-4653: sound/core/control.c in the ALSA control     implementation in the Linux kernel before 3.15.2 does     not ensure possession of a read/write lock, which allows     local users to cause a denial of service     (use-after-free) and obtain sensitive information from     kernel memory by leveraging /dev/snd/controlCX access.
    (bnc#883795)

  - CVE-2014-4654: The snd_ctl_elem_add function in     sound/core/control.c in the ALSA control implementation     in the Linux kernel before 3.15.2 does not check     authorization for SNDRV_CTL_IOCTL_ELEM_REPLACE commands,     which allows local users to remove kernel controls and     cause a denial of service (use-after-free and system     crash) by leveraging /dev/snd/controlCX access for an     ioctl call. (bnc#883795)

  - CVE-2014-4655: The snd_ctl_elem_add function in     sound/core/control.c in the ALSA control implementation     in the Linux kernel before 3.15.2 does not properly     maintain the user_ctl_count value, which allows local     users to cause a denial of service (integer overflow and     limit bypass) by leveraging /dev/snd/controlCX access     for a large number of SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl     calls. (bnc#883795)

  - CVE-2014-4656: Multiple integer overflows in     sound/core/control.c in the ALSA control implementation     in the Linux kernel before 3.15.2 allow local users to     cause a denial of service by leveraging     /dev/snd/controlCX access, related to (1) index values     in the snd_ctl_add function and (2) numid values in the     snd_ctl_remove_numid_conflict function. (bnc#883795)

  - CVE-2014-4667: The sctp_association_free function in     net/sctp/associola.c in the Linux kernel before 3.15.2     does not properly manage a certain backlog value, which     allows remote attackers to cause a denial of service     (socket outage) via a crafted SCTP packet. (bnc#885422)

  - CVE-2014-4699: The Linux kernel before 3.15.4 on Intel     processors does not properly restrict use of a     non-canonical value for the saved RIP address in the     case of a system call that does not use IRET, which     allows local users to leverage a race condition and gain     privileges, or cause a denial of service (double fault),     via a crafted application that makes ptrace and fork     system calls. (bnc#885725)

  - CVE-2014-5077: The sctp_assoc_update function in     net/sctp/associola.c in the Linux kernel through 3.15.8,     when SCTP authentication is enabled, allows remote     attackers to cause a denial of service (NULL pointer     dereference and OOPS) by starting to establish an     association between two endpoints immediately after an     exchange of INIT and INIT ACK chunks to establish an     earlier association between these endpoints in the     opposite direction. (bnc#889173)

  - CVE-2013-4299: Interpretation conflict in     drivers/md/dm-snap-persistent.c in the Linux kernel     through 3.11.6 allows remote authenticated users to     obtain sensitive information or modify data via a     crafted mapping to a snapshot block device. (bnc#846404)
