Do you remember recent Microsoft Word (and Wordpad) vulnerabilities while
reading .rtf documents? I realized that Sun StarOffice 5.1 is at least so
buggy as M$ products. There are a lot of ways to cause overflow and crash
(or execution of arbitrary code) while viewing documents - starting from
html with <a href="file://aaaaaaaaalotof...">, which will cause crash on
opening this document itself (you don't have to click that link). Also,
any other document with such hyperlink should cause instant crash (try
saving SO native document - .sdw - with some hyperlinks, then modyfing it
with binary editor). Just one example. Beautiful overflow while doing
strcpy().

1:1, Microsoft's move ;)
