Hi,

A while ago I reported a couple of bugs into your bugtracker about
issues in xfs_repair that I found through fuzzing (with the tool
american fuzzy lop).

http://oss.sgi.com/bugzilla/show_bug.cgi?id=1119
null pointer access

http://oss.sgi.com/bugzilla/show_bug.cgi?id=1120
out of bounds heap read access

http://oss.sgi.com/bugzilla/show_bug.cgi?id=1121
http://oss.sgi.com/bugzilla/show_bug.cgi?id=1122
2x assert

When opening these bugs I got an error message. I then contacted your
support and almost two months(!) later I got a reply telling me that I
should not use bugzilla, instead I should report bugs to this mailing
list.

Your webpage however clearly states that I should use bugzilla:
http://oss.sgi.com/projects/xfs/

This is all a bit ridiculous. If you don't want people to use your
bugzilla don't say so on your webpage and preferrably disable the
creation of new bugs.

Anyway: Please have a look at the bugs I reported (and once they're
fixed I'll happily re-test the code to see if there are more issues
that can be found via fuzzing).
