Summary

The __get_user_asm_ex macro in arch/x86/include/asm/uaccess.h in the Linux kernel before 4.7.5 does not initialize a certain integer variable, which allows local users to obtain sensitive information from kernel stack memory by triggering failure of a get_user_ex call.

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.

    "Several vulnerabilities have been discovered in the Linux kernel that
    may lead to a privilege escalation, denial of service or information
    leaks.
    
    CVE-2012-6704, CVE-2016-9793
    
    Eric Dumazet found that a local user with CAP_NET_ADMIN capability
    could set a socket's buffer size to be negative, leading to a denial
    of service or other security impact. Additionally, in kernel versions
    prior to 3.5, any user could do this if sysctl net.core.rmem_max was
    changed to a very large value.
    
    CVE-2015-1350 / #770492
    
    Ben Harris reported that local users could remove set-capability
    attributes from any file visible to them, allowing a denial of
    service.
    
    CVE-2015-8962
    
    Calvin Owens fouund that removing a SCSI device while it was being
    accessed through the SCSI generic (sg) driver led to a double- free,
    possibly causing a denial of service (crash or memory corruption) or
    privilege escalation. This could be exploited by local users with
    permision to access a SCSI device node.
    
    CVE-2015-8963
    
    Sasha Levin reported that hot-unplugging a CPU resulted in a
    use-after-free by the performance events (perf) subsystem, possibly
    causing a denial of service (crash or memory corruption) or privilege
    escalation. This could by exploited by any local user.
    
    CVE-2015-8964
    
    It was found that the terminal/serial (tty) subsystem did not reliably
    reset the terminal buffer state when the terminal line discipline was
    changed. This could allow a local user with access to a terminal
    device to read sensitive information from kernel memory.
    
    CVE-2016-7097
    
    Jan Kara found that changing the POSIX ACL of a file never cleared its
    set-group-ID flag, which should be done if the user changing it is not
    a member of the group-owner. In some cases, this would allow the
    user-owner of an executable to gain the privileges of the group-owner.
    
    CVE-2016-7910
    
    Vegard Nossum discovered that a memory allocation failure while
    handling a read of /proc/diskstats or /proc/partitions could lead to a
    use-after-free, possibly causing a denial of service (crash or memory
    corruption) or privilege escalation.
    
    CVE-2016-7911
    
    Dmitry Vyukov reported that a race between ioprio_get() and
    ioprio_set() system calls could result in a use-after-free, possibly
    causing a denial of service (crash) or leaking sensitive information.
    
    CVE-2016-7915
    
    Benjamin Tissoires found that HID devices could trigger an out-of-
    bounds memory access in the HID core. A physically present user could
    possibly use this for denial of service (crash) or to leak sensitive
    information.
    
    CVE-2016-8399
    
    Qidan He reported that the IPv4 ping socket implementation did not
    validate the length of packets to be sent. A user with permisson to
    use ping sockets could cause an out-of-bounds read, possibly resulting
    in a denial of service or information leak. However, on Debian systems
    no users have permission to create ping sockets by default.
    
    CVE-2016-8633
    
    Eyal Itkin reported that the IP-over-Firewire driver (firewire-net)
    did not validate the offset or length in link-layer fragmentation
    headers. This allowed a remote system connected by Firewire to write
    to memory after a packet buffer, leading to a denial of service
    (crash) or remote code execution.
    
    CVE-2016-8645
    
    Marco Grassi reported that if a socket filter (BPF program) attached
    to a TCP socket truncates or removes the TCP header, this could cause
    a denial of service (crash). This was exploitable by any local user.
    
    CVE-2016-8655
    
    Philip Pettersson found that the implementation of packet sockets
    (AF_PACKET family) had a race condition between enabling a transmit
    ring buffer and changing the version of buffers used, which could
    result in a use-after-free. A local user with the CAP_NET_ADMIN
    capability could exploit this for privilege escalation.
    
    CVE-2016-9178
    
    Al Viro found that a failure to read data from user memory might lead
    to a information leak on the x86 architecture (amd64 or i386).
    
    CVE-2016-9555
    
    Andrey Konovalov reported that the SCTP implementation does not
    validate 'out of the blue' packet chunk lengths early enough. A remote
    system able could use this to cause a denial of service (crash) or
    other security impact for systems using SCTP.
    
    CVE-2016-9576, CVE-2016-10088
    
    Dmitry Vyukov reported that using splice() with the SCSI generic
    driver led to kernel memory corruption. Local users with permision to
    access a SCSI device node could exploit this for privilege escalation.
    
    CVE-2016-9756
    
    Dmitry Vyukov reported that KVM for the x86 architecture (amd64 or
    i386) did not correctly handle the failure of certain instructions
    that require software emulation on older processors. This could be
    exploited by guest systems to leak sensitive information or for denial
    of service (log spam).
    
    CVE-2016-9794
    
    Baozeng Ding reported a race condition in the ALSA (sound) subsystem
    that could result in a use-after-free. Local users with access to a
    PCM sound device could exploit this for denial of service (crash or
    memory corruption) or other security impact.
    
    For Debian 7 'Wheezy', these problems have been fixed in version
    3.2.84-1. This version also includes bug fixes from upstream version
    3.2.84 and updates the PREEMPT_RT featureset to version 3.2.84-rt122.
    Finally, this version adds the option to mitigate security issues in
    the performance events (perf) subsystem by disabling use by
    unprivileged users. This can be done by setting sysctl
    kernel.perf_event_paranoid=3.
    
    For Debian 8 'Jessie', these problems have been fixed in version
    3.16.39-1 which will be included in the next point release (8.6).

(CVE-2017-1000251) It was discovered that the asynchronous I/O (aio) subsystem of the Linux kernel did not properly set permissions on aio memory mappings in some situations. An attacker could use this to more easily exploit other vulnerabilities. (CVE-2016-10044) Baozeng Ding and Andrey Konovalov discovered a race condition in the L2TPv3 IP Encapsulation implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-10200) Andreas Gruenbacher and Jan Kara discovered that the filesystem implementation in the Linux kernel did not clear the setgid bit during a setxattr call. A local attacker could use this to possibly elevate group privileges. (CVE-2016-7097) Sergej Schumilo, Ralf Spenneberg, and Hendrik Schwartke discovered that the key management subsystem in the Linux kernel did not properly allocate memory in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-8650) Vlad Tsyrklevich discovered an integer overflow vulnerability in the VFIO PCI driver for the Linux kernel. A local attacker with access to a vfio PCI device file could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-9083, CVE-2016-9084) It was discovered that an information leak existed in __get_user_asm_ex() in the Linux kernel. A local attacker could use this to expose sensitive information. (CVE-2016-9178) CAI Qian discovered that the sysctl implementation in the Linux kernel did not properly perform reference counting in some situations. An unprivileged attacker could use this to cause a denial of service (system hang). (CVE-2016-9191) It was discovered that the keyring implementation in the Linux kernel in some situations did not prevent special internal keyrings from being joined by userspace keyrings. A privileged local attacker could use this to bypass module verification. (CVE-2016-9604) It was discovered that an integer overflow existed in the trace subsystem of the Linux kernel. A local privileged attacker could use this to cause a denial of service (system crash). (CVE-2016-9754) Andrey Konovalov discovered that the IPv4 implementation in the Linux kernel did not properly handle invalid IP options in some situations. An attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2017-5970) Dmitry Vyukov discovered that the Linux kernel did not properly handle TCP packets with the URG flag. A remote attacker could use this to cause a denial of service. (CVE-2017-6214) It was discovered that a race condition existed in the AF_PACKET handling code in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-6346) It was discovered that the keyring implementation in the Linux kernel did not properly restrict searches for dead keys. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-6951) Dmitry Vyukov discovered that the generic SCSI (sg) subsystem in the Linux kernel contained a stack-based buffer overflow. A local attacker with access to an sg device could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-7187) Eric Biggers discovered a memory leak in the keyring implementation in the Linux kernel. A local attacker could use this to cause a denial of service (memory consumption). (CVE-2017-7472) It was discovered that a buffer overflow existed in the Broadcom FullMAC WLAN driver in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-7541). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
