Notes
- docker.io <not-affected> (Not built from/with a runc with "ambient capabilities")
- runc <not-affected> ("ambient capabilities" introduced later, cf bug #853240)
https://github.com/docker/docker/issues/27590
docker: https://github.com/docker/docker/pull/27610/commits/d60a3418d0268745dff38947bc8c929fbd24f837 (1.12.3)
runc: https://github.com/opencontainers/runc/commit/a83f5bac28554fa0fd49bc1559a3c79f5907348f
docker.io not directly affected but will need to be updated to include new runc version
runc: "ambient capabilities" functionality added upstream with https://github.com/opencontainers/runc/pull/1086
and later changes.
The actual fix seem to be to revert the commit which introduced ambient capabilities
in runc.
