hfs: fix namelength memory corruption (CVE-2008-5025)
commit d38b7aa7fc3371b52d036748028db50b585ade2e upstream
Fix a stack corruption caused by a corrupted hfs filesystem. If the
catalog name length is corrupted the memcpy overwrites the catalog btree
structure. Since the field is limited to HFS_NAMELEN bytes in the
structure and the file format, we throw an error if it is too long.
