The wacom_probe function in drivers/input/tablet/wacom_sys.c in the Linux kernel before 3.17 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.

According to the versions of the kernel packages installed, the EulerOS 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):** DISPUTED ** 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.
    NOTE: the author of the LZO algorithms says 'the Linux     kernel is *not* affected media hype.'(CVE-2014-4608)A     certain backport in the TCP Fast Open implementation     for the Linux kernel before 3.18 does not properly     maintain a count value, which allow local users to     cause a denial of service (system crash) via the Fast     Open feature, as demonstrated by visiting the     chrome://flags/#enable-tcp-fast-open URL when using     certain 3.10.x through 3.16.x kernel builds, including     longterm-maintenance releases and ckt (aka Canonical     Kernel Team) builds.(CVE-2015-3332)An elevation of     privilege vulnerability in the kernel scsi driver.
    Product: Android. Versions: Android kernel. Android ID     A-65023233.(CVE-2017-13168)An issue was discovered in     drivers/i2c/i2c-core-smbus.c in the Linux kernel before     4.14.15. There is an out of bounds write in the     function i2c_smbus_xfer_emulated.(CVE-2017-18551)An     issue was discovered in net/ipv6/ip6mr.c in the Linux     kernel before 4.11. By setting a specific socket     option, an attacker can control a pointer in kernel     land and cause an inet_csk_listen_stop general     protection fault, or potentially execute arbitrary code     under certain circumstances. The issue can be triggered     as root (e.g., inside a default LXC container or with     the CAP_NET_ADMIN capability) or after namespace     unsharing. This occurs because sk_type and protocol are     not checked in the appropriate part of the ip6_mroute_*     functions. NOTE: this affects Linux distributions that     use 4.9.x longterm kernels before     4.9.187.(CVE-2017-18509)An issue was discovered in the     Linux kernel before 4.14.11. A double free may be     caused by the function allocate_trace_buffer in the     file kernel/trace/trace.c.(CVE-2017-18595)An issue was     discovered in the Linux kernel through 4.17.10. There     is a NULL pointer dereference and panic in     hfsplus_lookup() in fs/hfsplus/dir.c when opening a     file (that is purportedly a hard link) in an hfs+     filesystem that has malformed catalog data, and is     mounted read-only without a metadata     directory.(CVE-2018-14617)An issue was discovered in     write_tpt_entry in drivers/infiniband/hw/cxgb4/mem.c in     the Linux kernel through 5.3.2. The cxgb4 driver is     directly calling dma_map_single (a DMA function) from a     stack variable. This could allow an attacker to trigger     a Denial of Service, exploitable if this driver is used     on an architecture for which this stack/DMA interaction     has security relevance.(CVE-2019-17075)Double free     vulnerability in the snd_usbmidi_create function in     sound/usb/midi.c in the Linux kernel before 4.5 allows     physically proximate attackers to cause a denial of     service (panic) or possibly have unspecified other     impact via vectors involving an invalid USB     descriptor.(CVE-2016-2384)fsamespace.c in the Linux     kernel through 3.16.1 does not properly restrict     clearing MNT_NODEV, MNT_NOSUID, and MNT_NOEXEC and     changing MNT_ATIME_MASK during a remount of a bind     mount, which allows local users to gain privileges,     interfere with backups and auditing on systems that had     atime enabled, or cause a denial of service (excessive     filesystem updating) on systems that had atime disabled     via a 'mount -o remount' command within a user     namespace.(CVE-2014-5207)fs/overlayfs/dir.c in the     OverlayFS filesystem implementation in the Linux kernel     before 4.6 does not properly verify the upper dentry     before proceeding with unlink and rename system-call     processing, which allows local users to cause a denial     of service (system crash) via a rename system call that     specifies a self-hardlink.(CVE-2016-6197)In the Linux     kernel before 4.1.4, a buffer overflow occurs when     checking userspace params in     drivers/media/dvb-frontends/cx24116.c. The maximum size     for a DiSEqC command is 6, according to the userspace     API. However, the code allows larger values such as     23.(CVE-2015-9289)In the Linux kernel through 5.3.2,     cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c     does not reject a long SSID IE, leading to a Buffer     Overflow.(CVE-2019-17133)Insufficient access control in     the Intel(R) PROSet/Wireless WiFi Software driver     before version 21.10 may allow an unauthenticated user     to potentially enable denial of service via adjacent     access.(CVE-2019-0136)Linux distributions that have not     patched their long-term kernels with     https://git.kernel.org/linus/a87938b2e246b81b4fb713edb3     71a9fa3c5c3c86 (committed on April 14, 2015). This     kernel vulnerability was fixed in April 2015 by commit     a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (backported to     Linux 3.10.77 in May 2015), but it was not recognized     as a security threat. With     CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE enabled, and a     normal top-down address allocation strategy,     load_elf_binary() will attempt to map a PIE binary into     an address range immediately below mm->mmap_base.
    Unfortunately, load_elf_ binary() does not take account     of the need to allocate sufficient space for the entire     binary which means that, while the first PT_LOAD     segment is mapped below mm->mmap_base, the subsequent     PT_LOAD segment(s) end up being mapped above     mm->mmap_base into the are that is supposed to be the     'gap' between the stack and the     binary.(CVE-2017-1000253)Race condition in the     sclp_ctl_ioctl_sccb function in     drivers/s390/char/sclp_ctl.c in the Linux kernel before     4.6 allows local users to obtain sensitive information     from kernel memory by changing a certain length value,     aka a 'double fetch'     vulnerability.(CVE-2016-6130)rtl_p2p_noa_ie in drivers     et/wireless/realtek/rtlwifi/ps.c in the Linux kernel     through 5.3.6 lacks a certain upper-bound check,     leading to a buffer     overflow.(CVE-2019-17666)sound/core/timer.c in the     Linux kernel through 4.6 does not initialize certain r1     data structures, which allows local users to obtain     sensitive information from kernel stack memory via     crafted use of the ALSA timer interface, related to the     (1) snd_timer_user_ccallback and (2)     snd_timer_user_tinterrupt     functions.(CVE-2016-4578)Systems with microprocessors     utilizing speculative execution and branch prediction     may allow unauthorized disclosure of information to an     attacker with local user access via a side-channel     analysis.(CVE-2017-5753)The acm_probe function in     drivers/usb/class/cdc-acm.c in the Linux kernel before     4.5.1 allows physically proximate attackers to cause a     denial of service (NULL pointer dereference and system     crash) via a USB device without both a control and a     data endpoint descriptor.(CVE-2016-3138)The     arcmsr_iop_message_xfer function in     drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel     through 4.8.2 does not restrict a certain length field,     which allows local users to gain privileges or cause a     denial of service (heap-based buffer overflow) via an     ARCMSR_MESSAGE_WRITE_WQBUFFER control     code.(CVE-2016-7425)The ati_remote2_probe function in     drivers/input/misc/ati_remote2.c in the Linux kernel     before 4.5.1 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-2016-2185)The     create_fixed_stream_quirk function in     sound/usb/quirks.c in the snd-usb-audio driver in the     Linux kernel before 4.5.1 allows physically proximate     attackers to cause a denial of service (NULL pointer     dereference or double free, and system crash) via a     crafted endpoints value in a USB device     descriptor.(CVE-2016-2184)The digi_port_init function     in drivers/usb/serial/digi_acceleport.c in the Linux     kernel before 4.5.1 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-2016-3140)The     do_remount function in fsamespace.c in the Linux kernel     through 3.16.1 does not maintain the MNT_LOCK_READONLY     bit across a remount of a bind mount, which allows     local users to bypass an intended read-only restriction     and defeat certain sandbox protection mechanisms via a     'mount -o remount' command within a user     namespace.(CVE-2014-5206)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-2016-2187)The hub_activate function in     drivers/usb/core/hub.c in the Linux kernel before 4.3.5     does not properly maintain a hub-interface data     structure, which allows physically proximate attackers     to cause a denial of service (invalid memory access and     system crash) or possibly have unspecified other impact     by unplugging a USB hub device.(CVE-2015-8816)The     ims_pcu_parse_cdc_data function in     drivers/input/misc/ims-pcu.c in the Linux kernel before     4.5.1 allows physically proximate attackers to cause a     denial of service (system crash) via a USB device     without both a master and a slave     interface.(CVE-2016-3689)The Linux Kernel running on     AMD64 systems will sometimes map the contents of PIE     executable, the heap or ld.so to where the stack is     mapped allowing attackers to more easily manipulate the     stack. Linux Kernel version 4.11.5 is     affected.(CVE-2017-1000379)The powermate_probe function     in drivers/input/misc/powermate.c in the Linux kernel     before 4.5.1 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-2016-2186)The signal     implementation in the Linux kernel before 4.3.5 on     powerpc platforms does not check for an MSR with both     the S and T bits set, which allows local users to cause     a denial of service (TM Bad Thing exception and panic)     via a crafted application.(CVE-2015-8844)The     snd_timer_user_params function in sound/core/timer.c in     the Linux kernel through 4.6 does not initialize a     certain data structure, which allows local users to     obtain sensitive information from kernel stack memory     via crafted use of the ALSA timer     interface.(CVE-2016-4569)The tm_reclaim_thread function     in arch/powerpc/kernel/process.c in the Linux kernel     before 4.4.1 on powerpc platforms does not ensure that     TM suspend mode exists before proceeding with a     tm_reclaim call, which allows local users to cause a     denial of service (TM Bad Thing exception and panic)     via a crafted application.(CVE-2015-8845)The VFS     subsystem in the Linux kernel 3.x provides an     incomplete set of requirements for setattr operations     that underspecifies removing extended privilege     attributes, which allows local users to cause a denial     of service (capability stripping) via a failed     invocation of a system call, as demonstrated by using     chown to remove a capability from the ping or Wireshark     dumpcap program.(CVE-2015-1350)The wacom_probe function     in drivers/input/tablet/wacom_sys.c in the Linux kernel     before 3.17 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-2016-3139)

The remote Oracle Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2019-4644 advisory.

  - The ecryptfs_privileged_open function in fs/ecryptfs/kthread.c in the Linux kernel before 4.6.3 allows     local users to gain privileges or cause a denial of service (stack memory consumption) via vectors     involving crafted mmap calls for /proc pathnames, leading to recursive pagefault handling. (CVE-2016-1583)

  - The qmi_wwan_bind function in drivers/net/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 information disclosure vulnerability in the Upstream kernel encrypted-keys. Product: Android. Versions:
    Android kernel. Android ID: A-70526974. (CVE-2017-13305)

  - The function hso_get_config_data in drivers/net/usb/hso.c in the Linux kernel through 4.19.8 reads if_num     from the USB device (as a u8) and uses it to index a small array, resulting in an object out-of-bounds     (OOB) read that potentially allows arbitrary read in the kernel address space. (CVE-2018-19985)

  - The Linux kernel before 4.8 allows local users to bypass ASLR on setuid programs (such as /bin/su) because     install_exec_creds() is called too late in load_elf_binary() in fs/binfmt_elf.c, and thus the     ptrace_may_access() check has a race condition when reading /proc/pid/stat. (CVE-2019-11190)

  - The wacom_probe function in drivers/input/tablet/wacom_sys.c in the Linux kernel before 3.17 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-2016-3139)

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

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 double free vulnerability was found in netlink_dump,     which could cause a denial of service 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-2016-9806i1/4%0

  - Memory leak in drivers/media/video/videobuf-core.c in     the videobuf subsystem in the Linux kernel 2.6.x     through 4.x allows local users to cause a denial of     service (memory consumption) by leveraging /dev/video     access for a series of mmap calls that require new     allocations, a different vulnerability than     CVE-2007-6761. NOTE: as of 2016-06-18, this affects     only 11 drivers that have not been updated to use     videobuf2 instead of videobuf.(CVE-2010-5321i1/4%0

  - drivers/hid/hid-ntrig.c in the Human Interface Device     (HID) subsystem in the Linux kernel through 3.11, when     CONFIG_HID_NTRIG is enabled, allows physically     proximate attackers to cause a denial of service (NULL     pointer dereference and OOPS) via a crafted     device.(CVE-2013-2896i1/4%0

  - The wacom_probe function in     drivers/input/tablet/wacom_sys.c in the Linux kernel     before 3.17 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-2016-3139i1/4%0

  - An integer overflow vulnerability in     ip6_find_1stfragopt() function was found. A local     attacker that has privileges (of CAP_NET_RAW) to open     raw socket can cause an infinite loop inside the     ip6_find_1stfragopt() function.(CVE-2017-7542i1/4%0

  - Memory leak in the virtio_gpu_object_create function in     drivers/gpu/drm/virtio/virtgpu_object.c in the Linux     kernel through 4.11.8 allows attackers to cause a     denial of service (memory consumption) by triggering     object-initialization failures.(CVE-2017-10810i1/4%0

  - The ping_recvmsg function in net/ipv4/ping.c in the     Linux kernel before 3.12.4 does not properly interact     with read system calls on ping sockets, which allows     local users to cause a denial of service (NULL pointer     dereference and system crash) by leveraging unspecified     privileges to execute a crafted     application.(CVE-2013-6432i1/4%0

  - The madvise_willneed function in the Linux kernel     allows local users to cause a denial of service     (infinite loop) by triggering use of MADVISE_WILLNEED     for a DAX mapping.(CVE-2017-18208i1/4%0

  - An issue was discovered in the Linux kernel through     4.18.8. The vmacache_flush_all function in     mm/vmacache.c mishandles sequence number overflows. An     attacker can trigger a use-after-free (and possibly     gain privileges) via certain thread creation, map,     unmap, invalidation, and dereference     operations.(CVE-2018-17182i1/4%0

  - The ieee80211_radiotap_iterator_init function in     net/wireless/radiotap.c in the Linux kernel before     3.11.7 does not check whether a frame contains any data     outside of the header, which might allow attackers to     cause a denial of service (buffer over-read) via a     crafted header.(CVE-2013-7027i1/4%0

  - The Btrfs implementation in the Linux kernel before     3.19 does not ensure that the visible xattr state is     consistent with a requested replacement, which allows     local users to bypass intended ACL settings and gain     privileges via standard filesystem operations (1)     during an xattr-replacement time window, related to a     race condition, or (2) after an xattr-replacement     attempt that fails because the data does not     fit.(CVE-2014-9710i1/4%0

  - A syntax vulnerability was discovered in the kernel's     ASN1.1 DER decoder, which could lead to memory     corruption or a complete local denial of service     through x509 certificate DER files. A local system user     could use a specially created key file to trigger     BUG_ON() in the public_key_verify_signature() function     (crypto/asymmetric_keys/public_key.c), to cause a     kernel panic and crash the system.(CVE-2016-2053i1/4%0

  - It was found that the Linux kernel's KVM subsystem did     not handle the VM exits gracefully for the invept     (Invalidate Translations Derived from EPT)     instructions. On hosts with an Intel processor and     invept VM exit support, an unprivileged guest user     could use these instructions to crash the     guest.(CVE-2014-3645i1/4%0

  - The packet_recvmsg function in net/packet/af_packet.c     in the Linux kernel before 3.12.4 updates a certain     length value before ensuring that an associated data     structure has been initialized, which allows local     users to obtain sensitive information from kernel     memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg     system call.(CVE-2013-7270i1/4%0

  - The init_new_context function in     arch/x86/include/asm/mmu_context.h in the Linux kernel,     before 4.12.10, does not correctly handle errors from     LDT table allocation when forking a new process. This     could allow a local attacker to achieve a     use-after-free or possibly have unspecified other     impact by running a specially crafted     program.(CVE-2017-17053i1/4%0

  - It was found that the sanity_check_raw_super() function     in 'fs/f2fs/super.c' file in the Linux kernel before     version 4.12-rc1 does not validate the f2fs filesystem     segment count. This allows an unprivileged local user     to cause a system panic and DoS. Due to the nature of     the flaw, privilege escalation cannot be fully ruled     out, although we believe it is     unlikely.(CVE-2017-10662i1/4%0

According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - The snd_timer_interrupt function in sound/core/timer.c     in the Linux kernel before 4.4.1 does not properly     maintain a certain linked list, which allows local     users to cause a denial of service (race condition and     system crash) via a crafted ioctl call.(CVE-2016-2545)

  - sound/core/timer.c in the Linux kernel before 4.4.1     uses an incorrect type of mutex, which allows local     users to cause a denial of service (race condition,     use-after-free, and system crash) via a crafted ioctl     call.(CVE-2016-2546)

  - sound/core/timer.c in the Linux kernel before 4.4.1     employs a locking approach that does not consider slave     timer instances, which allows local users to cause a     denial of service (race condition, use-after-free, and     system crash) via a crafted ioctl call.(CVE-2016-2547)

  - sound/core/timer.c in the Linux kernel before 4.4.1     retains certain linked lists after a close or stop     action, which allows local users to cause a denial of     service (system crash) via a crafted ioctl call,     related to the (1) snd_timer_close and (2)
    _snd_timer_stop functions.(CVE-2016-2548)

  - sound/core/hrtimer.c in the Linux kernel before 4.4.1     does not prevent recursive callback access, which     allows local users to cause a denial of service     (deadlock) via a crafted ioctl call.(CVE-2016-2549)

  - A resource-exhaustion vulnerability was found in the     kernel, where an unprivileged process could allocate     and accumulate far more file descriptors than the     process' limit. A local, unauthenticated user could     exploit this flaw by sending file descriptors over a     Unix socket and then closing them to keep the process'     fd count low, thereby creating kernel-memory or     file-descriptors exhaustion (denial of     service).(CVE-2016-2550)

  - It is possible for a single process to cause an OOM     condition by filling large pipes with data that are     never read. A typical process filling 4096 pipes with 1     MB of data will use 4 GB of memory and there can be     multiple such processes, up to a     per-user-limit.(CVE-2016-2847)

  - A security flaw was found in the Linux kernel that an     attempt to move page mapped by AIO ring buffer to the     other node triggers NULL pointer dereference at     trace_writeback_dirty_page(), because     aio_fs_backing_dev_info.dev is 0.(CVE-2016-3070)

  - A security flaw was found in the Linux kernel in the     mark_source_chains() function in     'net/ipv4/netfilter/ip_tables.c'. It is possible for a     user-supplied 'ipt_entry' structure to have a large     'next_offset' field.

The SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.57 to receive various security and bugfixes.

The following security bugs were fixed :

  - CVE-2015-8812: A flaw was found in the CXGB3 kernel     driver when the network was considered congested. The     kernel would incorrectly misinterpret the congestion as     an error condition and incorrectly free/clean up the     skb. When the device would then send the skb's queued,     these structures would be referenced and may panic the     system or allow an attacker to escalate privileges in a     use-after-free scenario. (bsc#966437)

  - CVE-2015-8816: A malicious USB device could cause a     kernel crash in the USB hub driver. (bnc#968010).

  - CVE-2016-2143: On zSeries a fork of a large process     could have caused memory corruption due to incorrect     page table handling. (bnc#970504)

  - CVE-2016-2184: A malicious USB device could cause a     kernel crash in the alsa usb-audio driver. (bsc#971125).

  - CVE-2016-2384: A malicious USB device could cause a     kernel crash in the alsa usb-audio driver. (bsc#966693)

  - CVE-2016-2782: A malicious USB device could cause a     kernel crash in the usb visor driver. (bnc#968670).

  - CVE-2016-3139: A malicious USB device could cause a     kernel crash in the wacom driver. (bnc#970909).

  - CVE-2016-3156: Removal of ipv4 interfaces with a large     number of IP addresses was taking very long.
    (bsc#971360).

  - CVE-2015-8709: kernel/ptrace.c in the Linux kernel     mishandled uid and gid mappings, which allowed local     users to gain privileges by establishing a user     namespace, waiting for a root process to enter that     namespace with an unsafe uid or gid, and then using the     ptrace system call. NOTE: the vendor states 'there is no     kernel bug here (bnc#960561).

The update package also includes non-security fixes. See advisory for details.

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.
