CVE-2018-1000004

Luo Quan reported a race condition in the ALSA (sound) sequencer core, between multiple ioctl operations. This could lead to a deadlock or use-after-free. A local user with access to a sequencer device could use this for denial of service or possibly for privilege escalation.

CVE-2018-1000199

Andy Lutomirski discovered that the ptrace subsystem did not sufficiently validate hardware breakpoint settings. Local users can use this to cause a denial of service, or possibly for privilege escalation, on x86 (amd64 and i386) and possibly other architectures.

Additionally, some mitigations for CVE-2017-5753 are included in this release :

CVE-2017-5753

Multiple researchers have discovered a vulnerability in various processors supporting speculative execution, enabling an attacker controlling an unprivileged process to read memory from arbitrary addresses, including from the kernel and all other processes running on the system.

This specific attack has been named Spectre variant 1 (bounds-check bypass) and is mitigated by identifying vulnerable code sections (array bounds checking followed by array access) and replacing the array access with the speculation-safe array_index_nospec() function.

More use sites will be added over time.

For Debian 7 'Wheezy', these problems have been fixed in version 3.2.101-1. This version also includes bug fixes from upstream versions up to and including 3.2.101. It also fixes a regression in the procfs hidepid option in the previous version (Debian bug #887106).

We recommend that you upgrade your linux packages.

  - A vulnerability was found in the Linux kernel's     kernel/events/core.c:perf_cpu_time_max_percent_handler(     ) function. Local privileged users could exploit this     flaw to cause a denial of service due to integer     overflow or possibly have unspecified other     impact.(CVE-2017-18255)

  - A flaw was found in the Linux kernel in the way a local     user could create keyrings for other users via keyctl     commands. This may allow an attacker to set unwanted     defaults, a denial of service, or possibly leak keyring     information between users.(CVE-2017-18270)

  - The mm subsystem in the Linux kernel through 4.10.10     does not properly enforce the CONFIG_STRICT_DEVMEM     protection mechanism, which allows local users to read     or write to kernel memory locations in the first     megabyte (and bypass slab-allocation access     restrictions) via an application that opens the     /dev/mem file, related to arch/x86/mm/init.c and     drivers/char/mem.c.(CVE-2017-7889)

  - The code in the drivers/scsi/libsas/sas_scsi_host.c     file in the Linux kernel allow a physically proximate     attacker to cause a memory leak in the ATA command     queue and, thus, denial of service by triggering     certain failure conditions.(CVE-2018-10021)

  - An issue was discovered in the XFS filesystem in     fs/xfs/libxfs/xfs_attr_leaf.c in the Linux kernel. A     NULL pointer dereference may occur for a corrupted xfs     image after xfs_da_shrink_inode() is called with a NULL     bp. This can lead to a system crash and a denial of     service.(CVE-2018-13094)

  - A flaw was found in the Linux Kernel in the     ucma_leave_multicast() function in     drivers/infiniband/core/ucma.c which allows access to a     certain data structure after freeing it in     ucma_process_join(). This allows an attacker to cause a     use-after-free bug and to induce kernel memory     corruption, leading to a system crash or other     unspecified impact. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2018-14734)

  - A race condition in the store_int_with_restart()     function in arch/x86/kernel/cpu/mcheck/mce.c in the     Linux kernel allows local users to cause a denial of     service (panic) by leveraging root access to write to     the check_interval file in a     /sys/devices/system/machinecheck/machinecheck (cpu     number) directory.(CVE-2018-7995)

    This could lead to a local elevation of privilege     enabling code execution as a privileged process with no     additional execution privileges needed. User     interaction is not needed for exploitation. Product:
    Android. Versions: Android kernel. Android ID:
    A-66954097.(CVE-2017-13216)

  - 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)

  - The rtnl_fill_link_ifmap function in     net/core/rtnetlink.c in the Linux kernel before 4.5.5     does not initialize a certain data structure, which     allows local users to obtain sensitive information from     kernel stack memory by reading a Netlink     message.(CVE-2016-4486)

  - The ip6gre_err function in net/ipv6/ip6_gre.c in the     Linux kernel allows remote attackers to have     unspecified impact via vectors involving GRE flags in     an IPv6 packet, which trigger an out-of-bounds     access.(CVE-2017-5897)

  - In the Linux kernel before version 4.12, Kerberos 5     tickets decoded when using the RXRPC keys incorrectly     assumes the size of a field. This could lead to the     size-remaining variable wrapping and the data pointer     going over the end of the buffer. This could possibly     lead to memory corruption and possible privilege     escalation.(CVE-2017-7482)

  - A flaw was found in the Linux Kernel where an attacker     may be able to have an uncontrolled read to     kernel-memory from within a vm guest. A race condition     between connect() and close() function may allow an     attacker using the AF_VSOCK protocol to gather a 4 byte     information leak or possibly intercept or corrupt     AF_VSOCK messages destined to other     clients.(CVE-2018-14625)

  - drivers/net/usb/asix_devices.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-2017-16647)

  - A memory leak in the ql_alloc_large_buffers() function     in drivers/net/ethernet/qlogic/qla3xxx.c in the Linux     kernel before 5.3.5 allows local users to cause a     denial of service (memory consumption) by triggering     pci_dma_mapping_error() failures, aka     CID-1acb8f2a7a9f.(CVE-2019-18806)

  - An issue was discovered in the fd_locked_ioctl function     in drivers/block/floppy.c in the Linux kernel through     4.15.7. The floppy driver will copy a kernel pointer to     user memory in response to the FDGETPRM ioctl. An     attacker can send the FDGETPRM ioctl and use the     obtained kernel pointer to discover the location of     kernel code and data and bypass kernel security     protections such as KASLR.(CVE-2018-7755)

  - The usbvision driver in the Linux kernel package     3.10.0-123.20.1.el7 through 3.10.0-229.14.1.el7 in Red     Hat Enterprise Linux (RHEL) 7.1 allows physically     proximate attackers to cause a denial of service     (panic) via a nonzero bInterfaceNumber value in a USB     device descriptor.(CVE-2015-7833)

  - A flaw that allowed an attacker to corrupt memory and     possibly escalate privileges was found in the mwifiex     kernel module while connecting to a malicious wireless     network.(CVE-2019-3846)

  - drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14     does not check the alloc_workqueue return value,     leading to a NULL pointer dereference.(CVE-2019-16231)

  - 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)

  - A flaw was found in the Linux kernel. A heap based     buffer overflow in mwifiex_uap_parse_tail_ies function     in drivers/net/wireless/marvell/mwifiex/ie.c might lead     to memory corruption and possibly other     consequences.(CVE-2019-10126)

  - The Bluetooth BR/EDR specification up to and including     version 5.1 permits sufficiently low encryption key     length and does not prevent an attacker from     influencing the key length negotiation. This allows     practical brute-force attacks (aka 'KNOB') that can     decrypt traffic and inject arbitrary ciphertext without     the victim noticing.(CVE-2019-9506)

  - An issue was discovered in net/wireless/nl80211.c in     the Linux kernel through 5.2.17. It does not check the     length of variable elements in a beacon head, leading     to a buffer overflow.(CVE-2019-16746)

  - In the hidp_process_report in bluetooth, there is an     integer overflow. This could lead to an out of bounds     write with no additional execution privileges needed.
    User interaction is not needed for exploitation.
    Product: Android Versions: Android kernel Android ID:
    A-65853588 References: Upstream kernel.(CVE-2018-9363)

  - 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)

  - rtl_p2p_noa_ie in     drivers/net/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)

  - arch/arm/mm/dma-mapping.c in the Linux kernel before     3.13 on ARM platforms, as used in Android before     2016-08-05 on Nexus 5 and 7 (2013) devices, does not     prevent executable DMA mappings, which might allow     local users to gain privileges via a crafted     application, aka Android internal bug 28803642 and     Qualcomm internal bug CR642735.(CVE-2014-9888)

  - 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)

  - The rds_ib_xmit function in net/rds/ib_send.c in the     Reliable Datagram Sockets (RDS) protocol implementation     in the Linux kernel 3.7.4 and earlier allows local     users to cause a denial of service (BUG_ON and kernel     panic) by establishing an RDS connection with the     source IP address equal to the IPoIB interface's own IP     address, as demonstrated by rds-ping.(CVE-2012-2372)

  - 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)

  - A memory leak in the bfad_im_get_stats() function in     drivers/scsi/bfa/bfad_attr.c in the Linux kernel     through 5.3.11 allows attackers to cause a denial of     service (memory consumption) by triggering     bfa_port_get_stats() failures, aka     CID-0e62395da2bd.(CVE-2019-19066)

  - The kernel in Android before 2016-08-05 on Nexus 7     (2013) devices allows attackers to gain privileges via     a crafted application, aka internal bug     28522518.(CVE-2016-3857)

  - arch/arm64/kernel/sys.c in the Linux kernel before 4.0     allows local users to bypass the 'strict page     permissions' protection mechanism and modify the     system-call table, and consequently gain privileges, by     leveraging write access.(CVE-2015-8967)

  - 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 __clear_user function in     arch/arm64/lib/clear_user.S in the Linux kernel before     3.17.4 on the ARM64 platform allows local users to     cause a denial of service (system crash) by reading one     byte beyond a /dev/zero page boundary.(CVE-2014-7843)

  - The x86/fpu (Floating Point Unit) subsystem in the     Linux kernel before 4.13.5, when a processor supports     the xsave feature but not the xsaves feature, does not     correctly handle attempts to set reserved bits in the     xstate header via the ptrace() or rt_sigreturn() system     call, allowing local users to read the FPU registers of     other processes on the system, related to     arch/x86/kernel/fpu/regset.c and     arch/x86/kernel/fpu/signal.c.(CVE-2017-15537)

  - ** DISPUTED ** Race condition in the     store_int_with_restart() function in     arch/x86/kernel/cpu/mcheck/mce.c in the Linux kernel     through 4.15.7 allows local users to cause a denial of     service (panic) by leveraging root access to write to     the check_interval file in a     /sys/devices/system/machinecheck/machinecheck     directory. NOTE: a third party has indicated that this     report is not security relevant.(CVE-2018-7995)

  - 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.(CVE-2014-4508)

  - arch/x86/kernel/tls.c in the Thread Local Storage (TLS)     implementation in the Linux kernel through 3.18.1     allows local users to bypass the espfix protection     mechanism, and consequently makes it easier for local     users to bypass the ASLR protection mechanism, via a     crafted application that makes a set_thread_area system     call and later reads a 16-bit value.(CVE-2014-8133)

  - arch/mips/include/asm/thread_info.h in the Linux kernel     before 3.14.8 on the MIPS platform does not configure
    _TIF_SECCOMP checks on the fast system-call path, which     allows local users to bypass intended PR_SET_SECCOMP     restrictions by executing a crafted application without     invoking a trace or audit subsystem.(CVE-2014-4157)

  - Integer signedness error in the oz_hcd_get_desc_cnf     function in drivers/staging/ozwpan/ozhcd.c in the     OZWPAN driver in the Linux kernel through 4.0.5 allows     remote attackers to cause a denial of service (system     crash) or possibly execute arbitrary code via a crafted     packet.(CVE-2015-4001)

  - drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver     in the Linux kernel through 4.0.5 does not ensure that     certain length values are sufficiently large, which     allows remote attackers to cause a denial of service     (system crash or large loop) or possibly execute     arbitrary code via a crafted packet, related to the (1)     oz_usb_rx and (2) oz_usb_handle_ep_data     functions.(CVE-2015-4002)

  - The oz_usb_handle_ep_data function in     drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver     in the Linux kernel through 4.0.5 allows remote     attackers to cause a denial of service (divide-by-zero     error and system crash) via a crafted     packet.(CVE-2015-4003)

  - The OZWPAN driver in the Linux kernel through 4.0.5     relies on an untrusted length field during packet     parsing, which allows remote attackers to obtain     sensitive information from kernel memory or cause a     denial of service (out-of-bounds read and system crash)     via a crafted packet.(CVE-2015-4004)

  - 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)

  - The print_binder_transaction_ilocked function in     drivers/android/binder.c in the Linux kernel 4.14.90     allows local users to obtain sensitive address     information by reading '*from *code *flags' lines in a     debugfs file.(CVE-2018-20510)

  - 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)

  - The saa7164_bus_get function in     drivers/media/pci/saa7164/saa7164-bus.c in the Linux     kernel through 4.11.5 allows local users to cause a     denial of service (out-of-bounds array access) or     possibly have unspecified other impact by changing a     certain sequence-number value, aka a 'double fetch'     vulnerability.(CVE-2017-8831)

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.

A weakness was found in the Linux kernel's implementation of random seed data. Programs, early in the boot sequence, could use the data allocated for the seed before it was sufficiently generated.
(CVE-2018-1108)

A flaw was found in the way the Linux kernel handled exceptions delivered after a stack switch operation via Mov SS or Pop SS instructions. During the stack switch operation, the processor did not deliver interrupts and exceptions, rather they are delivered once the first instruction after the stack switch is executed. An unprivileged system user could use this flaw to crash the system kernel resulting in the denial of service. (CVE-2018-8897)

A flaw was found in the Linux kernel's implementation of 32-bit syscall interface for bridging. This allowed a privileged user to arbitrarily write to a limited range of kernel memory. (CVE-2018-1068)

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 flaw was found in the Linux kernel where a crash can be triggered from unprivileged userspace during core dump on a POWER system with a certain configuration. This is due to a missing processor feature check and an erroneous use of transactional memory (TM) instructions in the core dump path leading to a denial of service.(CVE-2018-1091)

An address corruption flaw was discovered in the Linux kernel built with hardware breakpoint (CONFIG_HAVE_HW_BREAKPOINT) support. While modifying a h/w breakpoint via 'modify_user_hw_breakpoint' routine, an unprivileged user/process could use this flaw to crash the system kernel resulting in DoS OR to potentially escalate privileges on a the system.(CVE-2018-1000199)

A flaw was found in the way the Linux kernel's KVM hypervisor handled exceptions delivered after a stack switch operation via Mov SS or Pop SS instructions. During the stack switch operation, the processor did not deliver interrupts and exceptions, rather they are delivered once the first instruction after the stack switch is executed. An unprivileged KVM guest user could use this flaw to crash the guest or, potentially, escalate their privileges in the guest.(CVE-2018-1087)

A flaw was found in the Linux kernel's skcipher component, which affects the skcipher_recvmsg function. Attackers using a specific input can lead to a privilege escalation.(CVE-2017-13215)

The do_get_mempolicy() function in mm/mempolicy.c in the Linux kernel allows local users to hit a use-after-free bug via crafted system calls and thus cause a denial of service (DoS) or possibly have unspecified other impact. Due to the nature of the flaw, privilege escalation cannot be fully ruled out.(CVE-2018-10675)

A flaw was found in Linux kernel's KVM virtualization subsystem. The VMX code does not restore the GDT.LIMIT to the previous host value, but instead sets it to 64KB. With a corrupted GDT limit a host's userspace code has an ability to place malicious entries in the GDT, particularly to the per-cpu variables. An attacker can use this to escalate their privileges.(CVE-2018-10901)

A race condition in the store_int_with_restart() function in arch/x86/kernel/cpu/mcheck/mce.c in the Linux kernel allows local users to cause a denial of service (panic) by leveraging root access to write to the check_interval file in a /sys/devices/system/machinecheck/machinecheck<cpu number> directory.
