This issue stems from the /etc/passwd file being created with group-writable permissions during build time. In certain conditions, an attacker who can execute commands within an affected container, even as a non-root user, can leverage their membership in the root group to modify the /etc/passwd file. This could allow the attacker to add a new user with any arbitrary UID, including UID 0, leading to full root privileges within the container."}, {"lang": "es", "value": "Una falla de escalada de privilegios de contenedor fue encontrada en las im\u00e1genes de contenedor de KServe ModelMesh. Este problema se origina en que el archivo /etc /passwd es creado con permisos de escritura para el grupo durante el tiempo de compilaci\u00f3n. En ciertas condiciones, un atacante que puede ejecutar comandos dentro de un contenedor afectado, incluso como un usuario no-root, puede aprovechar su membres\u00eda en el grupo root para modificar el archivo /etc /passwd. Esto podr\u00eda permitir al atacante a\u00f1adir un nuevo usuario con cualquier UID arbitrario, incluyendo UID 0, lo que lleva a privilegios de root completos dentro del contenedor."}], "lastModified": "2026-04-15T00:35:42.020", "sourceIdentifier": "secalert@redhat.com"}
