Bug 768597 – <app-emulation/podman-3.0.1: insufficient network isolation between pods (CVE-2021-20199)

• Status: RESOLVED FIXED
• Product: Gentoo Security

[Description John Helmert III 2021-02-03 22:36:55 UTC]

CVE-2021-20199 (https://bugzilla.redhat.com/show_bug.cgi?id=1919050):

Rootless containers run with Podman, receive all traffic with a source IP address of 127.0.0.1 (including from remote hosts). This impacts containerized applications that trust localhost (127.0.01) connections by default and do not require authentication. This issue affects Podman 1.8.0 onwards.

Maintainer, is it possible to backport the patch? If not we'll have to wait
for a release.

There is https://github.com/containers/podman/pull/9221 which seems to be the backport to 2.2.1, but then again 3.0.0 was just released.
