e2fsck: added sanity check for xattr validation Add an extra validity test in check_ext_attr(). If an attribute's e_value_size is zero the current code does not allocate a region for it and as a result the e_value_offs value is not verified. However, if e_value_offs is very large then the later call to ext2fs_ext_attr_hash_entry() can dereference bad memory and crash e2fsck.
