need to update the following after security audit

[Leuy Eeelyu <sarawakbird yahoo com>]

Hi.. After the security audit, it is found that some
of the application in our RHEL box is old.  May I know
how to upgrade them??  Do you need to download the RPM
on the net or I can just do a
up2date-upgrade-to-release version kind of things.??? 


OpenSSH 3.6.1p2 (protocol 2.0)

Apache httpd 2.0.46 -need to upgrade to 2.0.5

Squid webproxy 2.5.STABLE3- need to  update the latest
patches

Where to get those patches?

MySQL 3.23.58- need to upgrade to version 4.0.21
Do we need to reconfigure the database after the
upgrade?
