"value": "An integer overflow flaw was found in the BFS file system driver in grub2. When reading a file with an indirect extent map, grub2 fails to validate the number of extent entries to be read. A crafted or corrupted BFS filesystem may cause an integer overflow during the file reading, leading to a heap of bounds read. As a consequence, sensitive data may be leaked, or grub2 will crash."

Al leer un archivo con un mapa de extensi\u00f3n indirecto, grub2 no puede validar la cantidad de entradas de extensi\u00f3n que se leer\u00e1n. Un sistema de archivos BFS manipulado o da\u00f1ado puede causar un desbordamiento de enteros durante la lectura del archivo, lo que genera una gran cantidad de lecturas de los l\u00edmites. Como consecuencia, se pueden filtrar datos confidenciales o grub2 puede fallar."
