Hello, I was wondering if any of you know why the CentOS repository are not updated? for example, i just heard about the bugs of the version <=1.4.4 of Squirrelmail and on their website there is already a stable packet 1.4.5, but in the CentOS repository the only available version is the 1.4.3 9a
Any ideas?
RedHat, and by proxy CentOS backport fixes to security problems rather than upgrading to new versions, as new versions can introduce new problems. What is released as an update by centos and RHEL is patched, so you can't really go by version number alone.
Another thing, im new using yum so i have a question, for example if i put "yum install squirrelmail1.4.5" but i have the version 1.4.3 already installed in my system, what happens? does the yum override the old version? what happens with the config files?
This depends on the RPM, and what's marked as a config file. For proper packages, config files are not replaced, and new default configs are created as configfilename.rpmnew. Also, to upgrade you don't need to tell it to install the new one. Simply do "yum update" or "yum upgrade". This will install check for any newer versions of packages that you have installed, and ask if it's okay to install them.

So are you saying that the packet I found in the CentOS repository (1.4.3) it's patched properly? when I do a "yum update" what im really doing?changing versions or not? just updating to patched versions? what if I want to install a new version of a package? what should i do to upgrade to a new version instead of a patched version? Anyway....why isnt the package of squirrelmail 1.4.5 in the repository? where can i find a description of the packages in the repository..i mean...how can i know the real version..the patches applied to it..and etc.
Is there a way to use yum only to fix security problems? or that is what it really do and i dont know it yet...the first time i run yum update..i download a lot of packages..but how can i know if they are new version or just security patches for my old ones...? If i regulary use the yum update should I be relax that I have all my packages up to date and with their security patches?
Thanks
