CVE-2025-8283
Full vulnerability record from the local CVENow database.
Description
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.

"value": "Se encontró una vulnerabilidad en el paquete netavark, una pila de red para contenedores utilizados con Podman. Debido a la eliminación del dominio de búsqueda dns.podman, netavark podría devolver servidores externos si se envía un registro A/AAAA válido como respuesta. Al crear un contenedor con un nombre determinado, este se usará como nombre de host del contenedor. Dado que el dominio de búsqueda de Podman ya no se agrega, el contenedor utiliza el archivo resolv.conf del host y el solucionador DNS intentará buscar en los dominios de búsqueda que contiene. Si uno de los dominios contiene el mismo nombre de host que el contenedor en ejecución, la conexión se redireccionará a servidores externos inesperados."
