Summary

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.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Subverting Environment Variable Values
    The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Browser Fingerprinting
    An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

    descriptionAccording 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

"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)

(system crash) or possibly execute arbitrary code. (CVE-2015-8955)

It was discovered that the SCSI generic (sg) driver in the Linux
kernel contained a double-free vulnerability. A local attacker could
use this to cause a denial of service (system crash). (CVE-2015-8962)

Sasha Levin discovered that a race condition existed in the
performance events and counters subsystem of the Linux kernel when
handling CPU unplug events. A local attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2015-8963)

Tilman Schmidt and Sasha Levin discovered a use-after-free condition
in the TTY implementation in the Linux kernel. A local attacker could
use this to expose sensitive information (kernel memory).
(CVE-2015-8964)

It was discovered that the fcntl64() system call in the Linux kernel
did not properly set memory limits when returning on 32-bit ARM
processors. A local attacker could use this to gain administrative
privileges. (CVE-2015-8966)

It was discovered that the system call table for ARM 64-bit processors
in the Linux kernel was not write-protected. An attacker could use
this in conjunction with another kernel vulnerability to execute
arbitrary code. (CVE-2015-8967)

It was discovered that the generic SCSI block layer in the Linux
kernel did not properly restrict write operations in certain
situations. A local attacker could use this to cause a denial of
service (system crash) or possibly gain administrative privileges.
(CVE-2016-10088)

Alexander Potapenko discovered a race condition in the Advanced Linux
Sound Architecture (ALSA) subsystem in the Linux kernel. A local
attacker could use this to expose sensitive information (kernel
memory). (CVE-2017-1000380)

Li Qiang discovered that the DRM driver for VMware Virtual GPUs in the
Linux kernel did not properly validate some ioctl arguments. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2017-7346)

Tuomas Haanpaa and Ari Kauppi discovered that the NFSv2 and NFSv3
server implementations in the Linux kernel did not properly check for
the end of buffer. A remote attacker could use this to craft requests
that cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2017-7895)

It was discovered that an integer underflow existed in the Edgeport
USB Serial Converter device driver of the Linux kernel. An attacker
with physical access could use this to expose sensitive information
(kernel memory). (CVE-2017-8924)

It was discovered that the USB ZyXEL omni.net LCD PLUS driver in the
Linux kernel did not properly perform reference counting. A local
attacker could use this to cause a denial of service (tty exhaustion).
(CVE-2017-8925)

Murray McAllister discovered that the DRM driver for VMware Virtual
GPUs in the Linux kernel did not properly initialize memory. A local
attacker could use this to expose sensitive information (kernel
memory). (CVE-2017-9605).

"According to the versions of the kernel packages installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerabilities :

  - The pagemap_open function in fs/proc/task_mmu.c in the
    Linux kernel before 3.19.3, as used in Android 6.0.1
    before 2016-03-01, allows local users to obtain
    sensitive physical-address information by reading a
    pagemap file, aka Android internal bug
    25739721.(CVE-2016-0823i1/4%0

  - drivers/hid/hid-steelseries.c in the Human Interface
    Device (HID) subsystem in the Linux kernel through
    3.11, when CONFIG_HID_STEELSERIES is enabled, allows
    physically proximate attackers to cause a denial of
    service (heap-based out-of-bounds write) via a crafted
    device.(CVE-2013-2891i1/4%0

  - The overlayfs implementation in the Linux kernel
    through 4.5.2 does not properly maintain POSIX ACL
    xattr data, which allows local users to gain privileges
    by leveraging a group-writable setgid
    directory.(CVE-2016-1575i1/4%0

  - Integer overflow in the vc4_get_bcl function in
    drivers/gpu/drm/vc4/vc4_gem.c in the VideoCore DRM
    driver in the Linux kernel before 4.9.7 allows local
    users to cause a denial of service or possibly have
    unspecified other impact via a crafted size value in a
    VC4_SUBMIT_CL ioctl call.(CVE-2017-5576i1/4%0

  - The KVM subsystem in the Linux kernel through 3.12.5
    allows local users to gain privileges or cause a denial
    of service (system crash) via a VAPIC synchronization
    operation involving a page-end
    address.(CVE-2013-6368i1/4%0

  - It was found that the code in net/sctp/socket.c in the
    Linux kernel through 4.10.1 does not properly restrict
    association peel-off operations during certain wait
    states, which allows local users to cause a denial of
    service (invalid unlock and double free) via a
    multithreaded application. This vulnerability was
    introduced by CVE-2017-5986 fix (commit
    2dcab5984841).(CVE-2017-6353i1/4%0

  - net/netfilter/nf_conntrack_proto_dccp.c in the Linux
    kernel through 3.13.6 uses a DCCP header pointer
    incorrectly, which allows remote attackers to cause a
    denial of service (system crash) or possibly execute
    arbitrary code via a DCCP packet that triggers a call
    to the (1) dccp_new, (2) dccp_packet, or (3) dccp_error
    function.(CVE-2014-2523i1/4%0

  - Race condition vulnerability was found in
    drivers/misc/mic/vop/vop_vringh.c in the MIC VOP driver
    in the Linux kernel before 4.6.1. MIC VOP driver does
    two successive reads from user space to read a variable
    length data structure. Local user can obtain sensitive
    information from kernel memory or can cause DoS by
    corrupting kernel memory if the data structure changes
    between the two reads.(CVE-2016-5728i1/4%0

  - An issue was discovered in the btrfs filesystem code in
    the Linux kernel. An invalid pointer dereference in
    io_ctl_map_page() when mounting and operating a crafted
    btrfs image is due to a lack of block group item
    validation in check_leaf_item() in
    fs/btrfs/tree-checker.c function. This could lead to a
    system crash and a denial of service.(CVE-2018-14613i1/4%0

  - A flaw was found in the way the Linux kernel handled GS
    segment register base switching when recovering from a
    #SS (stack segment) fault on an erroneous return to
    user space. A local, unprivileged user could use this
    flaw to escalate their privileges on the
    system.(CVE-2014-9322i1/4%0

  - The keyring_search_aux function in
    security/keys/keyring.c in the Linux kernel allows
    local users to cause a denial of service via a
    request_key system call for the 'dead' key
    type.(CVE-2017-6951i1/4%0

  - A flaw was found in the way the Linux kernel's XFS file
    system handled replacing of remote attributes under
    certain conditions. A local user with access to XFS
    file system mount could potentially use this flaw to
    escalate their privileges on the
    system.(CVE-2015-0274i1/4%0

  - A memory leak in the kernel_read_file function in
    fs/exec.c in the Linux kernel through 4.20.11 allows
    attackers to cause a denial of service (memory
    consumption) by triggering vfs_read
    failures.(CVE-2019-8980i1/4%0

  - A flaw was found in the kernel's implementation of the
    Berkeley Packet Filter (BPF). A local attacker could
    craft BPF code to crash the system by creating a
    situation in which the JIT compiler would fail to
    correctly optimize the JIT image on the last pass. This
    would lead to the CPU executing instructions that were
    not part of the JIT code.(CVE-2015-4700i1/4%0

  - A security flaw was discovered in
    nl80211_set_rekey_data() function in the Linux kernel
    since v3.1-rc1 through v4.13. This function does not
    check whether the required attributes are present in a
    netlink request. This request can be issued by a user
    with CAP_NET_ADMIN privilege and may result in NULL
    dereference and a system crash.(CVE-2017-12153i1/4%0

  - The atyfb_ioctl function in
    drivers/video/fbdev/aty/atyfb_base.c in the Linux
    kernel through 4.12.10 does not initialize a certain
    data structure, which allows local users to obtain
    sensitive information from kernel stack memory by
    reading locations associated with padding
    bytes.(CVE-2017-14156i1/4%0

  - kernel/events/core.c in the performance subsystem in
    the Linux kernel before 4.0 mismanages locks during
    certain migrations, which allows local users to gain
    privileges via a crafted application, aka Android
    internal bug 31095224.(CVE-2016-6787i1/4%0

  - 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-2015-8944i1/4%0

  - Race condition in the ioctl_file_dedupe_range function
    in fs/ioctl.c in the Linux kernel through 4.7 allows
    local users to cause a denial of service (heap-based
    buffer overflow) or possibly gain privileges by
    changing a certain count value, aka a 'double fetch'
    vulnerability.(CVE-2016-6516i1/4%0

  - It was found that the timer functionality in the Linux
    kernel ALSA subsystem is prone to a race condition
    between read and ioctl system call handlers, resulting
    in an uninitialized memory disclosure to user space. A
    local user could use this flaw to read information
    belonging to other users.(CVE-2017-1000380i1/4%0

"It was discovered that the Linux kernel did not properly initialize a
Wake- on-Lan data structure. A local attacker could use this to expose
sensitive information (kernel memory). (CVE-2014-9900)

It was discovered that the Linux kernel did not properly restrict
access to /proc/iomem. A local attacker could use this to expose
sensitive information. (CVE-2015-8944)

Alexander Potapenko discovered a race condition in the Advanced Linux
Sound Architecture (ALSA) subsystem in the Linux kernel. A local
attacker could use this to expose sensitive information (kernel
memory). (CVE-2017-1000380)

Li Qiang discovered that the DRM driver for VMware Virtual GPUs in the
Linux kernel did not properly validate some ioctl arguments. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2017-7346)

Jann Horn discovered that bpf in Linux kernel does not restrict the
output of the print_bpf_insn function. A local attacker could use this
to obtain sensitive address information. (CVE-2017-9150)

Murray McAllister discovered that the DRM driver for VMware Virtual
GPUs in the Linux kernel did not properly initialize memory. A local
attacker could use this to expose sensitive information (kernel
memory). (CVE-2017-9605).
