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.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - kernel: out of bounds read in drivers/media/usb/dvb-usb/technisat-usb2.c (CVE-2019-15505)

  - kernel: buffer-overflow hardening in WiFi beacon validation code. (CVE-2019-16746)

  - block/scsi_ioctl.c in the Linux kernel through 3.8 does not properly consider the SCSI device class during     authorization of SCSI commands, which allows local users to bypass intended access restrictions via an     SG_IO ioctl call that leverages overlapping opcodes. (CVE-2012-4542)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - kernel: Buffer overflow due to unbounded strcpy in ISDN I4L driver (CVE-2017-12762)

  - kernel: buffer-overflow hardening in WiFi beacon validation code. (CVE-2019-16746)

  - include/linux/init_task.h in the Linux kernel before 2.6.35 does not prevent signals with a process group     ID of zero from reaching the swapper process, which allows local users to cause a denial of service     (system crash) by leveraging access to this process group. (CVE-2010-5328)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

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)

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/gpu/msm/kgsl.c in the MSM graphics driver (aka     GPU driver) for the Linux kernel 3.x, as used in     Qualcomm Innovation Center (QuIC) Android contributions     for MSM devices and other products, mishandles the     KGSL_MEMFLAGS_GPUREADONLY flag, which allows attackers     to gain privileges by leveraging accidental read-write     mappings, aka Qualcomm internal bug     CR988993.(CVE-2016-2067i1/4%0

  - Integer overflow in the mem_check_range function in     drivers/infiniband/sw/rxe/rxe_mr.c in the Linux kernel     before 4.9.10 allows local users to cause a denial of     service (memory corruption), obtain sensitive     information from kernel memory, or possibly have     unspecified other impact via a write or read request     involving the 'RDMA protocol over infiniband' (aka Soft     RoCE) technology.(CVE-2016-8636i1/4%0

  - Heap-based buffer overflow in the     logi_dj_ll_raw_request function in     drivers/hid/hid-logitech-dj.c in the Linux kernel     before 3.16.2 allows physically proximate attackers to     cause a denial of service (system crash) or possibly     execute arbitrary code via a crafted device that     specifies a large report size for an LED     report.(CVE-2014-3183i1/4%0

  - The futex_requeue function in kernel/futex.c in the     Linux kernel, before 4.14.15, might allow attackers to     cause a denial of service (integer overflow) or     possibly have unspecified other impacts by triggering a     negative wake or requeue value. Due to the nature of     the flaw, privilege escalation cannot be fully ruled     out, although we believe it is     unlikely.(CVE-2018-6927i1/4%0

  - 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-2015-8816i1/4%0

  - It was found that the blk_rq_map_user_iov() function in     the Linux kernel's block device implementation did not     properly restrict the type of iterator, which could     allow a local attacker to read or write to arbitrary     kernel memory locations or cause a denial of service     (use-after-free) by leveraging write access to a     /dev/sg device.(CVE-2016-9576i1/4%0

  - A security flaw was found in the Linux kernel's     networking subsystem that destroying the network     interface with huge number of ipv4 addresses assigned     keeps 'rtnl_lock' spinlock for a very long time (up to     hour). This blocks many network-related operations,     including creation of new incoming ssh connections.The     problem is especially important for containers, as the     container owner has enough permissions to trigger this     and block a network access on a whole host, outside the     container.(CVE-2016-3156i1/4%0

  - The edge_bulk_in_callback function in     drivers/usb/serial/io_ti.c in the Linux kernel allows     local users to obtain sensitive information (in the     dmesg ringbuffer and syslog) from uninitialized kernel     memory by using a crafted USB device (posing as an     io_ti USB serial device) to trigger an integer     underflow.(CVE-2017-8924i1/4%0

  - The IPv4 implementation in the Linux kernel before     3.18.8 does not properly consider the length of the     Read-Copy Update (RCU) grace period for redirecting     lookups in the absence of caching, which allows remote     attackers to cause a denial of service (memory     consumption or system crash) via a flood of     packets.(CVE-2015-1465i1/4%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-2014-9728i1/4%0

  - net/ipv6/ip6_output.c in the Linux kernel through     3.11.4 does not properly determine the need for UDP     Fragmentation Offload (UFO) processing of small packets     after the UFO queueing of a large packet, which allows     remote attackers to cause a denial of service (memory     corruption and system crash) or possibly have     unspecified other impact via network traffic that     triggers a large response packet.(CVE-2013-4387i1/4%0

  - It was found that nfsd is missing permissions check     when setting ACL on files, this may allow a local users     to gain access to any file by setting a crafted     ACL.(CVE-2016-1237i1/4%0

  - In the Linux kernel before 4.13.5, a local user could     create keyrings for other users via keyctl commands,     setting unwanted defaults or causing a denial of     service.(CVE-2017-18270i1/4%0

  - An issue was discovered in the Linux kernel where an     integer overflow in kernel/time/posix-timers.c in the     POSIX timer code is caused by the way the overrun     accounting works. Depending on interval and expiry time     values, the overrun can be larger than INT_MAX, but the     accounting is int based. This basically makes the     accounting values, which are visible to user space via     timer_getoverrun(2) and siginfo::si_overrun,     random.(CVE-2018-12896i1/4%0

  - Since Linux kernel version 3.2, the mremap() syscall     performs TLB flushes after dropping pagetable locks. If     a syscall such as ftruncate() removes entries from the     pagetables of a task that is in the middle of mremap(),     a stale TLB entry can remain for a short time that     permits access to a physical page after it has been     released back to the page allocator and reused. This is     fixed in the following kernel versions: 4.9.135,     4.14.78, 4.18.16, 4.19.(CVE-2018-18281i1/4%0

  - The netfilter subsystem in the Linux kernel through     4.15.7 mishandles the case of a rule blob that contains     a jump but lacks a user-defined chain, which allows     local users to cause a denial of service (NULL pointer     dereference) by leveraging the CAP_NET_RAW or     CAP_NET_ADMIN capability, related to arpt_do_table in     net/ipv4/netfilter/arp_tables.c, ipt_do_table in     net/ipv4/netfilter/ip_tables.c, and ip6t_do_table in     net/ipv6/netfilter/ip6_tables.c.(CVE-2018-1065i1/4%0

  - The use of a kzalloc with an integer multiplication     allowed an integer overflow condition to be reached in     vfio_pci_intrs.c. This combined with CVE-2016-9083 may     allow an attacker to craft an attack and use     unallocated memory, potentially crashing the     machine.(CVE-2016-9084i1/4%0

  - 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-2016-3138i1/4%0

  - It was discovered that root can gain direct access to     an internal keyring, such as '.dns_resolver' in RHEL-7     or '.builtin_trusted_keys' upstream, by joining it as     its session keyring. This allows root to bypass module     signature verification by adding a new public key of     its own devising to the keyring.(CVE-2016-9604i1/4%0

  - An information leak flaw was found in the Linux     kernel's IEEE 802.11 wireless networking     implementation. When software encryption was used, a     remote attacker could use this flaw to leak up to 8     bytes of plaintext.(CVE-2014-8709i1/4%0

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. 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 installation on the remote host is affected by the following vulnerabilities :

  - An information-leak vulnerability was found in the     kernel when it truncated a file to a smaller size which     consisted of an inline extent that was compressed. The     data between the new file size and the old file size     was not discarded and the number of bytes used by the     inode were not correctly decremented, which gave the     wrong report for callers of the stat(2) syscall. This     wasted metadata space and allowed for the truncated     data to be leaked, and data corruption or loss to     occur. A caller of the clone ioctl could exploit this     flaw by using only standard file-system operations     without root access to read the truncated     data.(CVE-2015-8374)

  - A flaw was found in the Linux kernel's key management     system where it was possible for an attacker to     escalate privileges or crash the machine. If a user key     gets negatively instantiated, an error code is cached     in the payload area. A negatively instantiated key may     be then be positively instantiated by updating it with     valid data. However, the -i1/4zupdate key type method     must be aware that the error code may be     there.(CVE-2015-8539)

  - A NULL pointer dereference flaw was found in the way     the Linux kernel's network subsystem handled socket     creation with an invalid protocol identifier. A local     user could use this flaw to crash the     system.(CVE-2015-8543)

  - An out-of-bounds flaw was found in the kernel, where     the length of the sockaddr parameter was not checked in     the pptp_bind() and pptp_connect() functions. As a     result, more kernel memory was copied out than     required, leaking information from the kernel stack     (including kernel addresses). A local system user could     exploit this flaw to bypass kernel ASLR or leak other     information.(CVE-2015-8569)

  - 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-2015-8575)

  - The ovl_setattr function in fs/overlayfs/inode.c in the     Linux kernel through 4.3.3 attempts to merge distinct     setattr operations, which allows local users to bypass     intended access restrictions and modify the attributes     of arbitrary overlay files via a crafted     application.(CVE-2015-8660)

  - A NULL pointer dereference flaw was found in the Linux     kernel: the NFSv4.2 migration code improperly     initialized the kernel structure. A local,     authenticated user could use this flaw to cause a panic     of the NFS client (denial of service).(CVE-2015-8746)

  - 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)

  - An infinite-loop flaw was found in the kernel. When a     local user calls the sys_writev syscall with a     specially crafted sequence of iov structs, the     fuse_fill_write_pages kernel function might never     terminate, instead continuing in a tight loop. This     process cannot be terminated and requires a     reboot.(CVE-2015-8785)

  - A NULL-pointer dereference vulnerability was found in     the Linux kernel's TCP stack, in     net/netfilter/nf_nat_redirect.c in the     nf_nat_redirect_ipv4() function. A remote,     unauthenticated user could exploit this flaw to create     a system crash (denial of service).(CVE-2015-8787)

  - A use-after-free flaw was found in the CXGB3 kernel     driver when the network was considered to be congested.
    The kernel incorrectly misinterpreted the congestion as     an error condition and incorrectly freed or cleaned up     the socket buffer (skb). When the device then sent the     skb's queued data, these structures were referenced. A     local attacker could use this flaw to panic the system     (denial of service) or, with a local account, escalate     their privileges.(CVE-2015-8812)

  - 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 ioresources_init function in kernel/resource.c in     the Linux kernel through 4.7, as used in Android before     2016-08-05 on Nexus 6 and 7 (2013) devices, uses weak     permissions for /proc/iomem, which allows local users     to obtain sensitive information by reading this file,     aka Android internal bug 28814213 and Qualcomm internal     bug CR786116. NOTE: the permissions may be intentional     in most non-Android contexts.(CVE-2015-8944)

  - 'A flaw was found in the Linux kernel's implementation     of overlayfs. An attacker can leak file resources in     the system by opening a large file with write     permissions on a overlay filesystem that is     insufficient to deal with the size of the write.

  - When unmounting the underlying device, the system is     unable to free an inode and this will consume     resources. Repeating this for all available inodes and     memory will create a denial of service     situation.(CVE-2015-8953)'

  - The rfcomm_sock_bind function in     net/bluetooth/rfcomm/sock.c in the Linux kernel before     4.2 allows local users to obtain sensitive information     or cause a denial of service (NULL pointer dereference)     via vectors involving a bind system call on a Bluetooth     RFCOMM socket.(CVE-2015-8956)

  - 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-2015-8961)

  - A flaw was found in the Linux kernel SCSI subsystem,     which allowed a local user to gain privileges or cause     a denial of service (memory corruption and system     crash) by issuing an SG_IO ioctl call while a device     was being detached.(CVE-2015-8962)

  - Race condition in kernel/events/core.c in the Linux     kernel before 4.4 allows local users to gain privileges     or cause a denial of service via use-after-free     vulnerability by leveraging incorrect handling of an     swevent data structure during a CPU unplug     operation.(CVE-2015-8963)

  - The tty_set_termios_ldisc() function in     'drivers/tty/tty_ldisc.c' in the Linux kernel before     4.5 allows local users to obtain sensitive information     from kernel memory by reading a tty data     structure.(CVE-2015-8964)

  - 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)

  - 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)

  - A use-after-free flaw was discovered in the Linux     kernel's tty subsystem, which allows for the disclosure     of uncontrolled memory location and possible kernel     panic. The information leak is caused by a race     condition when attempting to set and read the tty line     discipline. A local attacker could use the TIOCSETD     (via tty_set_ldisc ) to switch to a new line discipline     a concurrent call to a TIOCGETD ioctl performing a read     on a given tty could then access previously allocated     memory. Up to 4 bytes could be leaked when querying the     line discipline or the kernel could panic with a     NULL-pointer dereference.(CVE-2016-0723)

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.

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service, information leak or data loss.

  - CVE-2013-4312, CVE-2016-2847     Tetsuo Handa discovered that users can use pipes queued     on local (Unix) sockets to allocate an unfair share of     kernel memory, leading to denial-of-service (resource     exhaustion).

  This issue was previously mitigated for the stable suite by limiting   the total number of files queued by each user on local sockets. The   new kernel version in both suites includes that mitigation plus   limits on the total size of pipe buffers allocated for each user.

  - CVE-2015-7566     Ralf Spenneberg of OpenSource Security reported that the     visor driver crashes when a specially crafted USB device     without bulk-out endpoint is detected.

  - CVE-2015-8767     An SCTP denial-of-service was discovered which can be     triggered by a local attacker during a heartbeat timeout     event after the 4-way handshake.

  - CVE-2015-8785     It was discovered that local users permitted to write to     a file on a FUSE filesystem could cause a denial of     service (unkillable loop in the kernel).

  - CVE-2015-8812     A flaw was found in the iw_cxgb3 Infiniband driver.
    Whenever it could not send a packet because the network     was congested, it would free the packet buffer but later     attempt to send the packet again. This use-after-free     could result in a denial of service (crash or hang),     data loss or privilege escalation.

  - CVE-2015-8816     A use-after-free vulnerability was discovered in the USB     hub driver. This may be used by a physically present     user for privilege escalation.

  - CVE-2015-8830     Ben Hawkes of Google Project Zero reported that the AIO     interface permitted reading or writing 2 GiB of data or     more in a single chunk, which could lead to an integer     overflow when applied to certain filesystems, socket or     device types. The full security impact has not been     evaluated.

  - CVE-2016-0723     A use-after-free vulnerability was discovered in the     TIOCGETD ioctl. A local attacker could use this flaw for     denial-of-service.

  - CVE-2016-0774     It was found that the fix for CVE-2015-1805 in kernel     versions older than Linux 3.16 did not correctly handle     the case of a partially failed atomic read. A local,     unprivileged user could use this flaw to crash the     system or leak kernel memory to user space.

  - CVE-2016-2069     Andy Lutomirski discovered a race condition in flushing     of the TLB when switching tasks on an x86 system. On an     SMP system this could possibly lead to a crash,     information leak or privilege escalation.

  - CVE-2016-2384     Andrey Konovalov found that a crafted USB MIDI device     with an invalid USB descriptor could trigger a     double-free. This may be used by a physically present     user for privilege escalation.

  - CVE-2016-2543     Dmitry Vyukov found that the core sound sequencer driver     (snd-seq) lacked a necessary check for a NULL pointer,     allowing a user with access to a sound sequencer device     to cause a denial-of service (crash).

  - CVE-2016-2544, CVE-2016-2546, CVE-2016-2547,     CVE-2016-2548

    Dmitry Vyukov found various race conditions in the sound     subsystem (ALSA)'s management of timers. A user with     access to sound devices could use these to cause a     denial-of-service (crash or hang) or possibly for     privilege escalation.

  - CVE-2016-2545     Dmitry Vyukov found a flaw in list manipulation in the     sound subsystem (ALSA)'s management of timers. A user     with access to sound devices could use this to cause a     denial-of-service (crash or hang) or possibly for     privilege escalation.

  - CVE-2016-2549     Dmitry Vyukov found a potential deadlock in the sound     subsystem (ALSA)'s use of high resolution timers. A user     with access to sound devices could use this to cause a     denial-of-service (hang).

  - CVE-2016-2550     The original mitigation of CVE-2013-4312, limiting the     total number of files a user could queue on local     sockets, was flawed. A user given a local socket opened     by another user, for example through the systemd socket     activation mechanism, could make use of the other user's     quota, again leading to a denial-of-service (resource     exhaustion). This is fixed by accounting queued files to     the sender rather than the socket opener.
