Re: Solaris 2.5.1 patch not effective?

[sfs () TC UMN EDU (Steve Siirila)]

I can confirm that the patch 104490-05 is indeed ineffective against at least
one root compromise bug.  We experienced such a compromise recently even with
the latest security patches (including 104490-05) installed.

We decided to simply make ufsdump/ufsrestore non-setuid, non-setgid as they
are never run by non-root users at our site anyways.
