Summary

The Linux kernel, versions 3.9+, is vulnerable to a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker may cause a denial of service condition by sending specially crafted IP fragments. Various vulnerabilities in IP fragmentation have been discovered and fixed over the years. The current vulnerability (CVE-2018-5391) became exploitable in the Linux kernel with the increase of the IP fragment reassembly queue size.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Server Side Include (SSI) Injection
    An attacker can use Server Side Include (SSI) Injection to send code to a web application that then gets executed by the web server. Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.
  • Cross Zone Scripting
    An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security. In a zone-based model, pages belong to one of a set of zones corresponding to the level of privilege assigned to that page. Pages in an untrusted zone would have a lesser level of access to the system and/or be restricted in the types of executable content it was allowed to invoke. In a cross-zone scripting attack, a page that should be assigned to a less privileged zone is granted the privileges of a more trusted zone. This can be accomplished by exploiting bugs in the browser, exploiting incorrect configuration in the zone controls, through a cross-site scripting attack that causes the attackers' content to be treated as coming from a more trusted page, or by leveraging some piece of system functionality that is accessible from both the trusted and less trusted zone. This attack differs from "Restful Privilege Escalation" in that the latter correlates to the inadequate securing of RESTful access methods (such as HTTP DELETE) on the server, while cross-zone scripting attacks the concept of security zones as implemented by a browser.
  • Cross Site Scripting through Log Files
    An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
  • Command Line Execution through SQL Injection
    An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.

"The remote NewStart CGSL host, running version MAIN 4.05, has kernel packages installed that are affected by multiple
vulnerabilities:

  - A flaw was found in the Linux kernel's implementation of
    the SCTP protocol. A remote attacker could trigger an
    out-of-bounds read with an offset of up to 64kB
    potentially causing the system to crash. (CVE-2016-9555)

  - An exploitable memory corruption flaw was found in the
    Linux kernel. The append path can be erroneously
    switched from UFO to non-UFO in ip_ufo_append_data()
    when building an UFO packet with MSG_MORE option. If
    unprivileged user namespaces are available, this flaw
    can be exploited to gain root privileges.
    (CVE-2017-1000112)

  - A bug in the 32-bit compatibility layer of the ioctl
    handling code of the v4l2 video driver in the Linux
    kernel has been found. A memory protection mechanism
    ensuring that user-provided buffers always point to a
    userspace memory were disabled, allowing destination
    address to be in a kernel space. This flaw could be
    exploited by an attacker to overwrite a kernel memory
    from an unprivileged userspace process, leading to
    privilege escalation. (CVE-2017-13166)

  - An industry-wide issue was found in the way many modern
    microprocessor designs have implemented speculative
    execution of instructions (a commonly used performance
    optimization). There are three primary variants of the
    issue which differ in the way the speculative execution
    can be exploited. Variant CVE-2017-5753 triggers the
    speculative execution by performing a bounds-check
    bypass. It relies on the presence of a precisely-defined
    instruction sequence in the privileged code as well as
    the fact that memory accesses may cause allocation into
    the microprocessor's data cache even for speculatively
    executed instructions that never actually commit
    (retire). As a result, an unprivileged attacker could
    use this flaw to cross the syscall boundary and read
    privileged memory by conducting targeted cache side-
    channel attacks. (CVE-2017-5753)

  - An industry-wide issue was found in the way many modern
    microprocessor designs have implemented speculative
    execution of instructions (a commonly used performance
    optimization). There are three primary variants of the
    issue which differ in the way the speculative execution
    can be exploited. Variant CVE-2017-5754 relies on the
    fact that, on impacted microprocessors, during
    speculative execution of instruction permission faults,
    exception generation triggered by a faulting access is
    suppressed until the retirement of the whole instruction
    block. In a combination with the fact that memory
    accesses may populate the cache even when the block is
    being dropped and never committed (executed), an
    unprivileged local attacker could use this flaw to read
    privileged (kernel space) memory by conducting targeted
    cache side-channel attacks. Note: CVE-2017-5754 affects
    Intel x86-64 microprocessors. AMD x86-64 microprocessors
    are not affected by this issue. (CVE-2017-5754)

  - It was found that the packet_set_ring() function of the
    Linux kernel's networking implementation did not
    properly validate certain block-size data. A local
    attacker with CAP_NET_RAW capability could use this flaw
    to trigger a buffer overflow resulting in a system crash
    or a privilege escalation. (CVE-2017-7308)

  - A use-after-free vulnerability was found in DCCP socket
    code affecting the Linux kernel since 2.6.16. This
    vulnerability could allow an attacker to their escalate
    privileges. (CVE-2017-8824)

  - 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)

  - An integer overflow flaw was found in the Linux kernel's
    create_elf_tables() function. An unprivileged local user
    with access to SUID (or otherwise privileged) binary
    could use this flaw to escalate their privileges on the
    system. (CVE-2018-14634)

  - An industry-wide issue was found in the way many modern
    microprocessor designs have implemented speculative
    execution of Load & Store instructions (a commonly used
    performance optimization). It relies on the presence of
    a precisely-defined instruction sequence in the
    privileged code as well as the fact that memory read
    from address to which a recent memory write has occurred
    may see an older value and subsequently cause an update
    into the microprocessor's data cache even for
    speculatively executed instructions that never actually
    commit (retire). As a result, an unprivileged attacker
    could use this flaw to read privileged memory by
    conducting targeted cache side-channel attacks.
    (CVE-2018-3639)

  - An industry-wide issue was found in the way many modern
    microprocessor designs have implemented speculative
    execution of instructions past bounds check. The flaw
    relies on the presence of a precisely-defined
    instruction sequence in the privileged code and the fact
    that memory writes occur to an address which depends on
    the untrusted value. Such writes cause an update into
    the microprocessor's data cache even for speculatively
    executed instructions that never actually commit
    (retire). As a result, an unprivileged attacker could
    use this flaw to influence speculative execution and/or
    read privileged memory by conducting targeted cache
    side-channel attacks. (CVE-2018-3693)

  - A flaw named SegmentSmack was found in the way the Linux
    kernel handled specially crafted TCP packets. A remote
    attacker could use this flaw to trigger time and
    calculation expensive calls to tcp_collapse_ofo_queue()
    and tcp_prune_ofo_queue() functions by sending specially
    modified packets within ongoing TCP sessions which could
    lead to a CPU saturation and hence a denial of service
    on the system. Maintaining the denial of service
    condition requires continuous two-way TCP sessions to a
    reachable open port, thus the attacks cannot be
    performed using spoofed IP addresses. (CVE-2018-5390)

  - A flaw named FragmentSmack was found in the way the
    Linux kernel handled reassembly of fragmented IPv4 and
    IPv6 packets. A remote attacker could use this flaw to
    trigger time and calculation expensive fragment
    reassembly algorithm by sending specially crafted
    packets which could lead to a CPU saturation and hence a
    denial of service on the system. (CVE-2018-5391)

    descriptionAccording to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - Modern operating systems implement virtualization of physical memory to efficiently use available system resources and provide inter-domain protection through access control and isolation. The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimisation) in combination with handling of page-faults caused by terminated virtual to physical address resolving process. As a result, an unprivileged attacker could use this flaw to read privileged memory of the kernel or other processes and/or cross guest/host boundaries to read host memory by conducting targeted cache side-channel attacks. (CVE-2018-3620, CVE-2018-3646) - A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP packets. A remote attacker could use this flaw to trigger time and calculation expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() functions by sending specially modified packets within ongoing TCP sessions which could lead to a CPU saturation and hence a denial of service on the system.

    descriptionThe remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel packages installed that are affected by multiple vulnerabilities: - A buffer overflow vulnerability due to a lack of input filtering of incoming fragmented datagrams was found in the IP-over-1394 driver [firewire-net] in a fragment handling code in the Linux kernel. The vulnerability exists since firewire supported IPv4, i.e. since version 2.6.31 (year 2009) till version v4.9-rc4. A maliciously formed fragment with a respectively large datagram offset would cause a memcpy() past the datagram buffer, which would cause a system panic or possible arbitrary code execution. The flaw requires [firewire-net] module to be loaded and is remotely exploitable from connected firewire devices, but not over a local network. (CVE-2016-8633) - A bug in the 32-bit compatibility layer of the ioctl handling code of the v4l2 video driver in the Linux kernel has been found. A memory protection mechanism ensuring that user-provided buffers always point to a userspace memory were disabled, allowing destination address to be in a kernel space. This flaw could be exploited by an attacker to overwrite a kernel memory from an unprivileged userspace process, leading to privilege escalation.

For more information on this set of information leaks, check out https://www.suse.com/support/kb/doc/?id=7023736 The following security bugs were fixed: CVE-2016-10741: fs/xfs/xfs_aops.c allowed local users to cause a denial of service (system crash) because there is a race condition between direct and memory-mapped I/O (associated with a hole) that is handled with BUG_ON instead of an I/O failure (bnc#1114920 bnc#1124010). CVE-2017-1000407: By flooding the diagnostic port 0x80 an exception can be triggered leading to a kernel panic (bnc#1071021). CVE-2017-16533: The usbhid_parse function in drivers/hid/usbhid/hid-core.c allowed local users to cause a denial of service (out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066674). CVE-2017-7273: The cp_report_fixup function in drivers/hid/hid-cypress.c allowed physically proximate attackers to cause a denial of service (integer underflow) or possibly have unspecified other impact via a crafted HID report (bnc#1031240).

    descriptionThis update for the Linux Kernel 3.12.74-60_64_104 fixes several issues. The following security issues were fixed : CVE-2019-9213: Expand_downwards in mm/mmap.c lacked a check for the mmap minimum address, which made it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task (bsc#1128378). CVE-2019-7221: Fixed a user-after-free vulnerability in the KVM hypervisor related to the emulation of a preemption timer, allowing an guest user/process to crash the host kernel. (bsc#1124734). CVE-2019-6974: kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandled reference counting because of a race condition, leading to a use-after-free (bsc#1124729). CVE-2018-5391: The Linux kernel was vulnerable to a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker might have caused a denial of service condition by sending specially crafted IP fragments. Various vulnerabilities in IP fragmentation have been discovered and fixed over the years.

    description- CVE-2018-5391 (FragmentSmack) Juha-Matti Tilli discovered a flaw in the way the Linux kernel handled reassembly of fragmented IPv4 and IPv6 packets. A remote attacker can take advantage of this flaw to trigger time and calculation expensive fragment reassembly algorithms by sending specially crafted packets, leading to remote denial of service. This is mitigated by reducing the default limits on memory usage for incomplete fragmented packets. The same mitigation can be achieved without the need to reboot, by setting the sysctls : net.ipv4.ipfrag_low_thresh = 196608 net.ipv6.ip6frag_low_thresh = 196608 net.ipv4.ipfrag_high_thresh = 262144 net.ipv6.ip6frag_high_thresh = 262144 The default values may still be increased by local configuration if necessary.

    descriptionThis update for the Linux Kernel 3.12.61-52_125 fixes several issues. The following security issues were fixed : CVE-2019-9213: Expand_downwards in mm/mmap.c lacked a check for the mmap minimum address, which made it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task (bsc#1128378). CVE-2019-7221: Fixed a user-after-free vulnerability in the KVM hypervisor related to the emulation of a preemption timer, allowing an guest user/process to crash the host kernel. (bsc#1124734). CVE-2018-5391: The Linux kernel was vulnerable to a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker might have caused a denial of service condition by sending specially crafted IP fragments. Various vulnerabilities in IP fragmentation have been discovered and fixed over the years. The current vulnerability (CVE-2018-5391) became exploitable in the Linux kernel with the increase of the IP fragment reassembly queue size (bsc#1103098). 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.

    descriptionThe remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel-rt packages installed that are affected by multiple vulnerabilities: - A buffer overflow vulnerability due to a lack of input filtering of incoming fragmented datagrams was found in the IP-over-1394 driver [firewire-net] in a fragment handling code in the Linux kernel. The vulnerability exists since firewire supported IPv4, i.e. since version 2.6.31 (year 2009) till version v4.9-rc4. A maliciously formed fragment with a respectively large datagram offset would cause a memcpy() past the datagram buffer, which would cause a system panic or possible arbitrary code execution. The flaw requires [firewire-net] module to be loaded and is remotely exploitable from connected firewire devices, but not over a local network. (CVE-2016-8633) - The Linux Kernel imposes a size restriction on the arguments and environmental strings passed through RLIMIT_STACK/RLIMIT_INFINITY, but does not take the argument and environment pointers into account, which allows attackers to bypass this limitation. (CVE-2017-1000365) - A bug in the 32-bit compatibility layer of the ioctl handling code of the v4l2 video driver in the Linux kernel has been found. A memory protection mechanism ensuring that user-provided buffers always point to a userspace memory were disabled, allowing destination address to be in a kernel space. This flaw could be exploited by an attacker to overwrite a kernel memory from an unprivileged userspace process, leading to privilege escalation.

    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation or denial of service. CVE-2018-5390 (SegmentSmack) Juha-Matti Tilli discovered that a remote attacker can trigger the worst case code paths for TCP stream reassembly with low rates of specially crafted packets, leading to remote denial of service. CVE-2018-5391 (FragmentSmack) Juha-Matti Tilli discovered a flaw in the way the Linux kernel handled reassembly of fragmented IPv4 and IPv6 packets. A remote attacker can take advantage of this flaw to trigger time and calculation expensive fragment reassembly algorithms by sending specially crafted packets, leading to remote denial of service. This is mitigated by reducing the default limits on memory usage for incomplete fragmented packets. The same mitigation can be achieved without the need to reboot, by setting the sysctls : net.ipv4.ipfrag_high_thresh = 262144 net.ipv6.ip6frag_high_thresh = 262144 net.ipv4.ipfrag_low_thresh = 196608 net.ipv6.ip6frag_low_thresh = 196608 The default values may still be increased by local configuration if necessary. CVE-2018-13405 Jann Horn discovered that the inode_init_owner function in fs/inode.c in the Linux kernel allows local users to create files with an unintended group ownership allowing attackers to escalate privileges by making a plain file executable and SGID.
