Given the following code containing errors, provide Common Weakness Enumeration (CWE) identifiers and corresponding messages in JSON format. Each identified weakness should have a unique entry in the JSON array.

	err = hfs_brec_read(fd, &tmp, sizeof(hfsplus_cat_entry));
	if (err)
		return err;

	type = be16_to_cpu(tmp.type);

 'cwe': ['CWE-119'], 'message': 'hfsplus: fix Buffer overflow with a corrupted image

When an hfsplus image gets corrupted it might happen that the catalog
namelength field gets b0rked.  If we mount such an image the memcpy() in
hfsplus_cat_build_key_uni() writes more than the 255 that fit in the name
field.  Depending on the size of the overwritten data, we either only get
memory corruption or also trigger an oops like this:

Since hfsplus_cat_build_key_uni() returns void and only has one callsite,
the check is performed at the callsite.
