github.com/docker/distribution fixed: 2.7.0-rc.0 
Upgrade github.com/docker/distribution to 2.7.0-rc.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/docker/distribution

How to Check if You Are Affected

To determine whether your application is affected by CVE-2017-11468, inspect your project dependencies for Github.com/docker/distribution:

inspect dependencies for github.com/docker/distribution

Analyze the terminal output to locate any version of Github.com/docker/distribution in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.7.0-rc.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-770: Allocation of Resources Without Limits or Throttling, where the product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated. In Github.com/docker/distribution, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Docker Registry before 2.6.2 in Docker Distribution does not properly restrict the amount of content accepted from a user, which allows remote attackers to cause a denial of service (memory consumption) via the manifest endpoint. ### Specific Go Packages Affected github.com/docker/distribution/registry/storage github.com/docker/distribution/registry/handlers
