Summary

The DefaultLinuxSpec function in oci/defaults.go in Docker Moby through 17.03.2-ce does not block /proc/scsi pathnames, which allows attackers to trigger data loss (when certain older Linux kernels are used) by leveraging Docker container access to write a "scsi remove-single-device" line to /proc/scsi/scsi, aka SCSI MICDROP.

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.

"This update for docker, docker-runc, containerd,
golang-github-docker-libnetwork fixes several issues.

These security issues were fixed :

  - CVE-2017-16539: The DefaultLinuxSpec function in
    oci/defaults.go docker did not block /proc/scsi
    pathnames, which allowed attackers to trigger data loss
    (when certain older Linux kernels are used) by
    leveraging Docker container access to write a 'scsi
    remove-single-device' line to /proc/scsi/scsi, aka SCSI
    MICDROP (bnc#1066801)

  - CVE-2017-14992: Lack of content verification in docker
    allowed a remote attacker to cause a Denial of Service
    via a crafted image layer payload, aka gzip bombing.
    (bnc#1066210)

These non-security issues were fixed :

  - bsc#1059011: The systemd service helper script used a
    timeout of 60 seconds to start the daemon, which is
    insufficient in cases where the daemon takes longer to
    start. Instead, set the service type from 'simple' to
    'notify' and remove the now superfluous helper script.

  - bsc#1057743: New requirement with new version of
    docker-libnetwork.

  - bsc#1032287: Missing docker systemd configuration.

  - bsc#1057743: New 'symbol' for libnetwork requirement.

  - bsc#1057743: Update secrets patch to handle 'old'
    containers that have orphaned secret data no longer
    available on the host.

  - bsc#1055676: Update patches to correctly handle volumes
    and mounts when Docker is running with user namespaces
    enabled.

  - bsc#1045628:: Add patch to make the dm storage driver
    remove a container's rootfs mountpoint before attempting
    to do libdm operations on it. This helps avoid
    complications when live mounts will leak into
    containers.

  - bsc#1069758: Upgrade Docker to v17.09.1_ce (and obsolete
    docker-image-migrator).

  - bsc#1021227: bsc#1029320 bsc#1058173 -- Enable docker
    devicemapper support for deferred removal/deletion
    within Containers module.

  - bsc#1046024: Correct interaction between Docker and
    SuSEFirewall2, to avoid breaking Docker networking after
    boot.

  - bsc#1048046: Build with -buildmode=pie to make all
    binaries PIC.

  - bsc#1072798: Remove dependency on obsolete bridge-utils.

  - bsc#1064926: Set --start-timeout=2m by default to match
    upstream. 

  - bsc#1065109, bsc#1053532: Use the upstream makefile so
    that Docker can get the commit ID in `docker info`.

Please note that the 'docker-runc' package is just a rename of the old
'runc' package to match that we now ship the Docker fork of runc. This
update was imported from the SUSE:SLE-12:Update update project."
