More information:

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 packages.
