Descriptions
In the Linux kernel, the following vulnerability has been resolved:
fat: fix uninitialized field in nostale filehandles
When fat_encode_fh_nostale() encodes file handle without a parent it
stores only first 10 bytes of the file handle. However the length of the
file handle must be a multiple of 4 so the file handle is actually 12
bytes long and the last two bytes remain uninitialized. This is not
great at we potentially leak uninitialized information with the handle
to userspace. Properly initialize the full handle length.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: fat: corrige el campo no inicializado en los identificadores de archivos notale Cuando fat_encode_fh_nostale() codifica el identificador de archivo sin un padre, almacena solo los primeros 10 bytes del identificador de archivo. Sin embargo, la longitud del identificador del archivo debe ser múltiplo de 4, por lo que el identificador del archivo tiene en realidad 12 bytes de longitud y los dos últimos bytes permanecen sin inicializar. Esto no es bueno porque potencialmente filtramos información no inicializada con el identificador al espacio de usuario. Inicialice correctamente toda la longitud del mango.
