Although this one wasn't, now that I've checked it up (sorry about
that). Using check_host mode against a resolvable hostname allocates a
host-table that may be too small to hold all targets. Writing to the
table works nicely, since it's just shuffling of pointers taken care of
on the heap but when it tries to access any of the structs variables it
crashes with SIGSEGV. This is read access only, so it's not a security
problem, but annoying all the same.
http://oss.op5.se/nagios/op5plugins-2005-10-14.tar.gz holds an updated
version, which also fixes a less annoying bug in check_hpjd along with
some minor stuff in check_users (for instance).
