In the Linux kernel, the following vulnerability has been resolved: partitions: mac: fix handling of bogus partition table Fix several issues in partition probing: - The bailout for a bad partoffset must use put_dev_sector(), since the preceding read_part_sector() succeeded. - If the partition table claims a silly sector size like 0xfff bytes (which results in partition table entries straddling sector boundaries), bail out instead of accessing out-of-bounds memory. - We must not assume that the partition table contains proper NUL termination - use strnlen() and strncmp() instead of strlen() and strcmp().
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: particiones: mac: se corrige el manejo de la tabla de particiones falsa Corrige varios problemas en el sondeo de particiones: - El rescate para un partoffset incorrecto debe usar put_dev_sector(), ya que el read_part_sector() anterior tuvo éxito. - Si la tabla de particiones reclama un tamaño de sector tonto como 0xfff bytes (lo que da como resultado que las entradas de la tabla de particiones se extiendan a ambos lados de los límites del sector), salga en lugar de acceder a la memoria fuera de los límites. - No debemos asumir que la tabla de particiones contiene la terminación NUL adecuada: use strnlen() y strncmp() en lugar de strlen() y strcmp().
