My boss asked me to check on whether this problem was fixed for FreeBSD 
4.10.  I didn't see any advisories related to this, and FreeBSD is still 
showing as vulnerable on the CERT web site.  It doesn't look like a fix 
for this has been committed to any of the 4.X branches.  Any word on this?

Thanks for the help.
