    =====================================================================
    
    1. Summary:
    
    An update for docker is now available for Red Hat Enterprise Linux 7
    Extras.
    
    Red Hat Product Security has rated this update as having a security impact
    of Important. 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.
    
    2. Relevant releases/architectures:
    
    Red Hat Enterprise Linux 7 Extras - aarch64, ppc64le, s390x, x86_64
    
    3. Description:
    
    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.
