Security Incidents: IRIX "gr" core dumps

[Geoff Galitz <galitz () chem berkeley edu>]

We have a hacked IRIX box where the intruder hijacked a
user password then apparently attacked the box locally via
a buffer overflow.  We found a series of core dumps in the
hijacked user directory generated by "gr."

Unfortunately, I cannot find any references to what gr actually
is or a known exploit for it.  Perhaps someone on the list
has more information on this?
