RedHat: RHSA-2019-0304:01 Important: docker security update
Summary
Docker is an open-source engine that automates the deployment of any
application as a lightweight, portable, self-sufficient container that runs
virtually anywhere.
Security Fix(es):
* A flaw was found in the way runc handled system file descriptors when
running containers. A malicious container could use this flaw to overwrite
contents of the runc binary and consequently run arbitrary commands on the
container host system. (CVE-2019-5736)
Additional details about this flaw, including mitigation information, can
be found in the vulnerability article linked from the Reference section.
For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.
