Both patches validate the catalog name length.

The following is the description of the hfs bug:
"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

It is possible to use the 7-hexdigit instead of the usual 40-hexdigit
SHA1 hash to refer to the commit ID.

Thanks, Eugene
