Summary
In the netavark package, a network stack for containers used with Podman, the dns.podman search domain was removed. As a result, a container may use the host's resolv.conf, and if one of the search domains contains a hostname matching the container's name, DNS queries may be forwarded to external servers.
Risk Assessment
The organization risks that network traffic from containers may be redirected to unexpected external servers, potentially leading to data leakage or man-in-the-middle attacks.
Recommendation
It is recommended to update the netavark package to the latest version that restores proper DNS search domain handling for Podman containers.
Original NVD description (English source)
A vulnerability was found in the netavark package, a network stack for containers used with Podman. Due to dns.podman search domain being removed, netavark may return external servers if a valid A/AAAA record is sent as a response. When creating a container with a given name, this name will be used as the hostname for the container itself, as the podman's search domain is not added anymore the container is using the host's resolv.conf, and the DNS resolver will try to look into the search domains contained on it. If one of the domains contain a name with the same hostname as the running container, the connection will forward to unexpected external servers.
