    Package        : docker.io
    CVE ID         : CVE-2020-13401
    Debian Bug     : 962141
    
    Etienne Champetier discovered that Docker, a Linux container runtime,
    created network bridges which by default accept IPv6 router advertisements.
    This could allow an attacker with the CAP_NET_RAW capability in a
    container to spoof router advertisements, resulting in information
    disclosure or denial of service.
    
    For the stable distribution (buster), this problem has been fixed in
    version 18.09.1+dfsg1-7.1+deb10u2.
    
    We recommend that you upgrade your docker.io packages.
    
    For the detailed security status of docker.io please refer to
    its security tracker page at:
