Synopsis :

The remote Red Hat host is missing a security update.

Description :

An update for docker-distribution is now available for Red Hat
Enterprise Linux 7 Extras.

Red Hat Product Security has rated this update as having a security
impact of Low. 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.

The docker-distribution package provides the tool set to support the
Docker Registry version 2.

The following packages have been upgraded to a later upstream version:
docker-distribution (2.6.2). (BZ#1479494)

Security Fix(es) :

* It was found that docker-distribution did not properly restrict
memory allocation size for a registry instance through the manifest
endpoint. An attacker could send a specially crafted request that
would exhaust the memory of the docker-distribution service.
