CVE-2018-15664 (opens in a new tab)How to fix?
Upgrade RHEL:7 docker-client to version 2:1.13.1-102.git7f2769b.el7 or higher.
This issue was patched in RHSA-2019:1910.
NVD Description
Note: Versions mentioned in the description apply only to the upstream docker-client package and not the docker-client package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
In Docker through 18.06.1-ce-rc2, the API endpoints behind the 'docker cp' command are vulnerable to a symlink-exchange attack with Directory Traversal, giving attackers arbitrary read-write access to the host filesystem with root privileges, because daemon/archive.go does not do archive operations on a frozen filesystem (or from within a chroot).
