Solaris7 and ff.core

[russell () CSCORP COM (Russell Van Tassell)]

Forgive me as I just started playing with Solaris 7 and don't recall
seeing this yet posted to Bugtraq.

It would appear as though an old bug with the OpenWeirdos File Mangler
has crept up again in Solaris 7 (I believe patch 106222-01 was supposed
to fix it back in Solaris 2.6 (and 106224-01 in Solaris 2.5.1)).  Very
basically, using ff.core it is possible for a normal user to overwrite
arbitrary files on the system (that would include things like /etc/shadow)
and do serious damage to the system (I will leave that exercise to the
reader).

Admins should remove the setuid and setgid bits from ff.core.

Regards,
Russell
