ext2: Add sanity checks for group and filesystem size
Description

In the Linux kernel, the following vulnerability has been resolved: ext2: Add sanity checks for group and filesystem size Add sanity check that filesystem size does not exceed the underlying device size and that group size is big enough so that metadata can fit into it. This avoid trying to mount some crafted filesystems with extremely large group counts.
