Summary

libcontainer/user/user.go in runC before 0.1.0, as used in Docker before 1.11.2, improperly treats a numeric UID as a potential username, which allows local users to gain privileges via a numeric username in the password file in a container.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Accessing, Modifying or Executing Executable Files
    An attack of this type exploits a system's configuration that allows an attacker to either directly access an executable file, for example through shell access; or in a possible worst case allows an attacker to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
  • Leverage Executable Code in Non-Executable Files
    An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
  • Blue Boxing
    This type of attack against older telephone switches and trunks has been around for decades. A tone is sent by an adversary to impersonate a supervisor signal which has the effect of rerouting or usurping command of the line. While the US infrastructure proper may not contain widespread vulnerabilities to this type of attack, many companies are connected globally through call centers and business process outsourcing. These international systems may be operated in countries which have not upgraded Telco infrastructure and so are vulnerable to Blue boxing. Blue boxing is a result of failure on the part of the system to enforce strong authorization for administrative functions. While the infrastructure is different than standard current applications like web applications, there are historical lessons to be learned to upgrade the access control for administrative functions.
  • Restful Privilege Elevation
    Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic. This means that unless the services are properly ACL'd and the application's service implementation are following these guidelines then an HTTP request can easily execute a delete or update on the server side. The attacker identifies a HTTP Get URL such as http://victimsite/updateOrder, which calls out to a program to update orders on a database or other resource. The URL is not idempotent so the request can be submitted multiple times by the attacker, additionally, the attacker may be able to exploit the URL published as a Get method that actually performs updates (instead of merely retrieving data). This may result in malicious or inadvertent altering of data on the server.
  • Target Programs with Elevated Privileges
    This attack targets programs running with elevated privileges. The attacker would try to leverage a bug in the running program and get arbitrary code to execute with elevated privileges. For instance an attacker would look for programs that write to the system directories or registry keys (such as HKLM, which stores a number of critical Windows environment variables). These programs are typically running with elevated privileges and have usually not been designed with security in mind. Such programs are excellent exploit targets because they yield lots of power when they break. The malicious user try to execute its code at the same level as a privileged system call.

Extras.

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

Docker is an open source engine that automates the deployment of any
application as a lightweight, portable, self-sufficient container that
will run virtually anywhere.

Security Fix(es) :

* It was found that Docker would launch containers under the specified
UID instead of a username. An attacker able to launch a container
could use this flaw to escalate their privileges to root within the
launched container. (CVE-2016-3697)

This issue was discovered by Mrunal Patel (Red Hat).

Bug Fix(es) :

* The process of pulling an image spawns a new 'goroutine' for each
layer in the image manifest. If any of these downloads, everything
stops and an error is returned, even though other goroutines would
still be running and writing output through a progress reader which is
attached to an http response writer. Since the request handler had
already returned from the first error, the http server panics when one
of these download goroutines makes a write to the response writer
buffer. This bug has been fixed, and docker no longer panics when
pulling an image. (BZ#1264562)

* Previously, in certain situations, a container rootfs remained busy
during container removal. This typically happened if a container mount
point leaked into another mount namespace. As a consequence, container
removal failed. To fix this bug, a new docker daemon option
'dm.use_deferred_deletion' has been provided. If set to true, this
option will defer the container rootfs deletion. The user will see
success on container removal but the actual thin device backing the
rootfs will be deleted later when it is not busy anymore. (BZ#1190492)

* Previously, the Docker unit file had the 'Restart' option set to
'on-failure'. Consequently, the docker daemon was forced to restart
even in cases where it couldn't be started because of configuration or
other issues and this situation forced unnecessary restarts of the
docker-storage-setup service in a loop. This also caused real error
messages to be lost due to so many restarts. To fix this bug,
'Restart=on-failure' has been replaced with 'Restart=on-abnormal' in
the docker unit file. As a result, the docker daemon will not
automatically restart if it fails with an unclean exit code.
(BZ#1319783)

* Previously, the request body was incorrectly read twice by the
docker daemon and consequently, an EOF error was returned. To fix this
bug, the code which incorrectly read the request body the first time
has been removed. As a result, the EOF error is no longer returned and
the body is correctly read when really needed. (BZ#1329743)

Enhancement(s) :

* The /usr/bin/docker script now calls /usr/bin/docker-current or
/usr/bin/ docker-latest based on the value of the sysconfig variable
DOCKERBINARY present in /etc/sysconfig/docker. /usr/bin/docker and
/etc/sysconfig/docker provided by the docker-common package allow the
admin to configure which docker client binary gets called.
/usr/bin/docker will call /usr/bin/ docker-latest by default when
docker is not installed. If docker is installed, /usr/bin/docker will
call /usr/bin/docker-current by default, unless DOCKERBINARY is set to
/usr/bin/docker-latest in /etc/sysconfig/ docker. This way, you can
use docker-latest or docker without the need to check which version of
the daemon is currently running. (BZ#1328219)"
