Patrick is right, Red Hat will patch services but doesn't change the
default version number in their banners. That way, you don't really know
what level a service is, if you are trying to attack it.

Correct. Red Hat 7.3 is always Red Hat 7.3, and will always contain Apache
1.3.x, for example. This meets the needs of people who have written
applications to that version of Apache (and PHP, etc.) and who don't want
to risk breaking everything by moving to the latest and greatest Apache
2.0. However, Red Hat did - during the lifetime of RH 7.3 - back-port
security fixes from later releases of the software - presumably Apache 2.0,
for example.

I did a "rpm -q OpenSSH" and it came back with a older version. Maybe it
was patched and I couldn't tell..it is possible. But I know for sure I
running the newest now. =)

The only way you could tell what patches had been applied is by relating
the RPM patch level to the Red Hat security advisories. The Red Hat
openssh-3.5p1-9, for example, contained a fix for a buffer handling
vulnerability (http://www.cert.org/advisories/CA-2003-24.html) that was
fixed by the OpenSSH team in version 3.7.1 of their code. This strikes me
as a lot of double handling, although it meets the needs of those who want
a feature freeze for stability, but need security fixes. But talk about
confusing . . .
