CVE-2015-1843
Description
It was found that the fix for the CVE-2014-5277 issue was incomplete: the docker client could under certain circumstances erroneously fall back to HTTP when an HTTPS connection to a registry failed. This could allow a man-in-the-middle attacker to obtain authentication and image data from traffic sent from a client to the registry.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
