Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Attack through Shared Data An attacker exploits a data structure shared between multiple applications or an application pool to affect application behavior. Data may be shared between multiple applications or between multiple threads of a single application. Data sharing is usually accomplished through mutual access to a single memory location. If an attacker can manipulate this shared data (usually by co-opting one of the applications or threads) the other applications or threads using the shared data will often continue to trust the validity of the compromised shared data and use it in their calculations. This can result in invalid trust assumptions, corruption of additional data through the normal operations of the other users of the shared data, or even cause a crash or compromise of the sharing applications.
- Integer Attacks An attacker takes advantage of the structure of integer variables to cause these variables to assume values that are not expected by an application. For example, adding one to the largest positive integer in a signed integer variable results in a negative number. Negative numbers may be illegal in an application and the application may prevent an attacker from providing them directly, but the application may not consider that adding two positive numbers can create a negative number do to the structure of integer storage formats.
- Pointer Attack This attack involves an attacker manipulating a pointer within a target application resulting in the application accessing an unintended memory location. This can result in the crashing of the application or, for certain pointer values, access to data that would not normally be possible or the execution of arbitrary code. Since pointers are simply integer variables, Integer Attacks may often be used in Pointer Attacks.

NASL family Debian Local Security Checks NASL id DEBIAN_DSA-3981.NASL description Several vulnerabilities have been discovered in the Linux kernel that may lead to privilege escalation, denial of service or information leaks. - CVE-2017-7518 Andy Lutomirski discovered that KVM is prone to an incorrect debug exception (#DB) error occurring while emulating a syscall instruction. A process inside a guest can take advantage of this flaw for privilege escalation inside a guest. - CVE-2017-7558 (stretch only) Stefano Brivio of Red Hat discovered that the SCTP subsystem is prone to a data leak vulnerability due to an out-of-bounds read flaw, allowing to leak up to 100 uninitialized bytes to userspace. - CVE-2017-10661 (jessie only) Dmitry Vyukov of Google reported that the timerfd facility does not properly handle certain concurrent operations on a single file descriptor. This allows a local attacker to cause a denial of service or potentially execute arbitrary code. - CVE-2017-11600 Bo Zhang reported that the xfrm subsystem does not properly validate one of the parameters to a netlink message. Local users with the CAP_NET_ADMIN capability can use this to cause a denial of service or potentially to execute arbitrary code. - CVE-2017-12134 / #866511 / XSA-229 Jan H. Schoenherr of Amazon discovered that when Linux is running in a Xen PV domain on an x86 system, it may incorrectly merge block I/O requests. A buggy or malicious guest may trigger this bug in dom0 or a PV driver domain, causing a denial of service or potentially execution of arbitrary code. This issue can be mitigated by disabling merges on the underlying back-end block devices, e.g.:echo 2 > /sys/block/nvme0n1/queue/nomerges - CVE-2017-12146 (stretch only) Adrian Salido of Google reported a race condition in access to the last seen 2020-06-05 modified 2017-09-21 plugin id 103365 published 2017-09-21 reporter This script is Copyright (C) 2017-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/103365 title Debian DSA-3981-1 : linux - security update (BlueBorne) (Stack Clash) code # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from Debian Security Advisory DSA-3981.

If unprivileged users are permitted to access this attribute, this might allow them to gain privileges. - CVE-2017-12153 Bo Zhang reported that the cfg80211 (wifi) subsystem does not properly validate the parameters to a netlink message. Local users with the CAP_NET_ADMIN capability (in any user namespace with a wifi device) can use this to cause a denial of service. - CVE-2017-12154 Jim Mattson of Google reported that the KVM implementation for Intel x86 processors did not correctly handle certain nested hypervisor configurations. A malicious guest (or nested guest in a suitable L1 hypervisor) could use this for denial of service. - CVE-2017-14106 Andrey Konovalov discovered that a user-triggerable division by zero in the tcp_disconnect() function could result in local denial of service. - CVE-2017-14140 Otto Ebeling reported that the move_pages() system call performed insufficient validation of the UIDs of the calling and target processes, resulting in a partial ASLR bypass. This made it easier for local users to exploit vulnerabilities in programs installed with the set-UID permission bit set. - CVE-2017-14156 'sohu0106' reported an information leak in the atyfb video driver. A local user with access to a framebuffer device handled by this driver could use this to obtain sensitive information. - CVE-2017-14340 Richard Wareing discovered that the XFS implementation allows the creation of files with the 'realtime' flag on a filesystem with no realtime device, which can result in a crash (oops). A local user with access to an XFS filesystem that does not have a realtime device can use this for denial of service. - CVE-2017-14489 ChunYu Wang of Red Hat discovered that the iSCSI subsystem does not properly validate the length of a netlink message, leading to memory corruption. A local user with permission to manage iSCSI devices can use this for denial of service or possibly to execute arbitrary code. - CVE-2017-14497 (stretch only) Benjamin Poirier of SUSE reported that vnet headers are not properly handled within the tpacket_rcv() function in the raw packet (af_packet) feature. A local user with the CAP_NET_RAW capability can take advantage of this flaw to cause a denial of service (buffer overflow, and disk and memory corruption) or have other impact. - CVE-2017-1000111 Andrey Konovalov of Google reported a race condition in the raw packet (af_packet) feature. Local users with the CAP_NET_RAW capability can use this for denial of service or possibly to execute arbitrary code. - CVE-2017-1000112 Andrey Konovalov of Google reported a race condition flaw in the UDP Fragmentation Offload (UFO) code. A local user can use this flaw for denial of service or possibly to execute arbitrary code. - CVE-2017-1000251 / #875881 Armis Labs discovered that the Bluetooth subsystem does not properly validate L2CAP configuration responses, leading to a stack-based buffer overflow. This is one of several vulnerabilities dubbed 'Blueborne'. A nearby attacker can use this to cause a denial of service or possibly to execute arbitrary code on a system with Bluetooth enabled. - CVE-2017-1000252 (stretch only) Jan H. Schoenherr of Amazon reported that the KVM implementation for Intel x86 processors did not correctly validate interrupt injection requests. A local user with permission to use KVM could use this for denial of service. - CVE-2017-1000370 The Qualys Research Labs reported that a large argument or environment list can result in ASLR bypass for 32-bit PIE binaries. - CVE-2017-1000371 The Qualys Research Labs reported that a large argument or environment list can result in a stack/heap clash for 32-bit PIE binaries. - CVE-2017-1000380 Alexander Potapenko of Google reported a race condition in the ALSA (sound) timer driver, leading to an information leak. A local user with permission to access sound devices could use this to obtain sensitive information. Debian disables unprivileged user namespaces by default, but if they are enabled (via the kernel.unprivileged_userns_clone sysctl) then CVE-2017-11600, CVE-2017-14497 and CVE-2017-1000111 can be exploited by any local user." ); script_set_attribute( attribute:"see_also", value:"https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=866511" ); script_set_attribute( attribute:"see_also", value:"https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=875881" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-7518" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-7558" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-10661" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-11600" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-12134" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-12146" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-12153" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-12154" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-14106" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-14140" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-14156" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-14340" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-14489" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-14497" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-1000111" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-1000112" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-1000251" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-1000252" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-1000370" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-1000371" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-1000380" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-11600" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-14497" ); script_set_attribute( attribute:"see_also", value:"https://security-tracker.debian.org/tracker/CVE-2017-1000111" ); script_set_attribute( attribute:"see_also", value:"https://packages.debian.org/source/jessie/linux" ); script_set_attribute( attribute:"see_also", value:"https://packages.debian.org/source/stretch/linux" ); script_set_attribute( attribute:"see_also", value:"https://www.debian.org/security/2017/dsa-3981" ); script_set_attribute( attribute:"solution", value: "Upgrade the linux packages.

NASL family SuSE Local Security Checks NASL id SUSE_SU-2017-2847-1.NASL description The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.92 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-1000252: The KVM subsystem in the Linux kernel allowed guest OS users to cause a denial of service (assertion failure, and hypervisor hang or crash) via an out-of bounds guest_irq value, related to arch/x86/kvm/vmx.c and virt/kvm/eventfd.c (bnc#1058038). - CVE-2017-11472: The acpi_ns_terminate() function in drivers/acpi/acpica/nsutils.c in the Linux kernel did not flush the operand cache and causes a kernel stack dump, which allowed local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a crafted ACPI table (bnc#1049580). - CVE-2017-12134: The xen_biovec_phys_mergeable function in drivers/xen/biomerge.c in Xen might allow local OS guest users to corrupt block device data streams and consequently obtain sensitive memory information, cause a denial of service, or gain host OS privileges by leveraging incorrect block IO merge-ability calculation (bnc#1051790 bsc#1053919). - CVE-2017-12153: A security flaw was discovered in the nl80211_set_rekey_data() function in net/wireless/nl80211.c in the Linux kernel This function did not check whether the required attributes are present in a Netlink request. This request can be issued by a user with the CAP_NET_ADMIN capability and may result in a NULL pointer dereference and system crash (bnc#1058410). - CVE-2017-12154: The prepare_vmcs02 function in arch/x86/kvm/vmx.c in the Linux kernel did not ensure that the last seen 2020-06-01 modified 2020-06-02 plugin id 104171 published 2017-10-26 reporter This script is Copyright (C) 2017-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/104171 title SUSE SLED12 / SLES12 Security Update : kernel (SUSE-SU-2017:2847-1) (KRACK) code # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from SUSE update advisory SUSE-SU-2017:2847-1. # The text itself is copyright (C) SUSE. # include("compat.inc"); if (description) { script_id(104171); script_version("3.14"); script_cvs_date("Date: 2019/09/11 11:22:16"); script_cve_id("CVE-2017-1000252", "CVE-2017-11472", "CVE-2017-12134", "CVE-2017-12153", "CVE-2017-12154", "CVE-2017-13080", "CVE-2017-14051", "CVE-2017-14106", "CVE-2017-14489", "CVE-2017-15265", "CVE-2017-15649", "CVE-2017-6346"); script_xref(name:"IAVA", value:"2017-A-0310"); script_name(english:"SUSE SLED12 / SLES12 Security Update : kernel (SUSE-SU-2017:2847-1) (KRACK)"); script_summary(english:"Checks rpm output for the updated packages."); script_set_attribute( attribute:"synopsis", value:"The remote SUSE host is missing one or more security updates." ); script_set_attribute( attribute:"description", value: "The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.92 to receive various security and bugfixes.

NASL family Huawei Local Security Checks NASL id EULEROS_SA-2020-1396.NASL description According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - drivers/gpu/drm/radeon/radeon_display.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference. NOTE: A third-party software maintainer states that the work queue allocation is happening during device initialization, which for a graphics card occurs during boot. It is not attacker controllable and OOM at that time is highly unlikely.(CVE-2019-16230) - In the Linux kernel 5.4.0-rc2, there is a use-after-free (read) in the __blk_add_trace function in kernel/trace/blktrace.c (which is used to fill out a blk_io_trace structure and place it in a per-cpu sub-buffer).(CVE-2019-19768) - A flaw was discovered in the way that the KVM hypervisor handled instruction emulation for an L2 guest when nested virtualisation is enabled. Under some circumstances, an L2 guest may trick the L0 guest into accessing sensitive L1 resources that should be inaccessible to the L2 guest.(CVE-2020-2732) - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vc_do_resize function in drivers/tty/vt/vt.c.(CVE-2020-8647) - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the n_tty_receive_buf_common function in drivers/tty/n_tty.c.(CVE-2020-8648) - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vgacon_invert_region function in drivers/video/console/vgacon.c.(CVE-2020-8649) - ext4_protect_reserved_inode in fs/ext4/block_validity.c in the Linux kernel through 5.5.3 allows attackers to cause a denial of service (soft lockup) via a crafted journal size.(CVE-2020-8992) - An issue was discovered in the Linux kernel through 5.5.6. set_fdc in drivers/block/floppy.c leads to a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it, aka CID-2e90ca68b0d2.(CVE-2020-9383) - In kernel/compat.c in the Linux kernel before 3.17, as used in Google Chrome OS and other products, there is a possible out-of-bounds read. restart_syscall uses uninitialized data when restarting compat_sys_nanosleep.
