Re: Solaris 2.5.1 patch not effective?

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.

I have two reports from other UC campuses that exploits of the Solaris
ufsrestore bug are being used against *sparc* hosts.
At least one of the sites reports that patch 104490-05 (Solaris 2.5.1,
sparc arch) was applied on a system that was compromised (presumably
via this method).
Consider this an *inconclusive* warning that the Sun ufsrestore patch
*may* not be effective. I have a call into Sun on this one. If we
can get the binary of the exploit, it might be interesting.
[The reporting sites are BCC'ed on this note. If they want to go
public, its up to them.]

Been there, done that, erased the evidence, blackmailed the witnesses...
