Debian Security Advisory DSA-4716-1 security@debian.org

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:
https://security-tracker.debian.org/tracker/docker.io
