Description Eugene Teo (Security Response) 2008-11-03 04:09:34 EST
Description of problem:
Eric Sesterhenn reported: 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.
