Debian DSA-4716-1 : docker.io - security update

medium Nessus Plugin ID 138105

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the docker.io packages.

For the stable distribution (buster), this problem has been fixed in version 18.09.1+dfsg1-7.1+deb10u2.
