Descriptions

A vulnerability was found in CRI-O that causes memory or disk space exhaustion on the node for anyone with access to the Kube API. The ExecSync request runs commands in a container and logs the output of the command. This output is then read by CRI-O after command execution, and it is read in a manner where the entire file corresponding to the output of the command is read in. Thus, if the output of the command is large it is possible to exhaust the memory or the disk space of the node when CRI-O reads the output of the command. The highest threat from this vulnerability is system availability.

Se ha encontrado una vulnerabilidad en CRI-O que causa el agotamiento de la memoria o del espacio en disco en el nodo para cualquiera que tenga acceso a la API de Kube. La petición ExecSync ejecuta comandos en un contenedor y registra la salida del comando. Esta salida es leída por CRI-O después de la ejecución del comando, y es leída de manera que el archivo completo correspondiente a la salida del comando es leído. Así, si la salida del comando es grande es posible agotar la memoria o el espacio en disco del nodo cuando CRI-O lee la salida del comando. La mayor amenaza de esta vulnerabilidad es la disponibilidad del sistema
