Security updates for any Slackware release can be found in the /patches
subdirectory of the release tree. You can find these patches on every Slackware mirror, like this one: http://slackware.mirrors.tds.net/pub...-10.1/patches/
but you will have to download them yourselves.
After downloading alll patches, you can verify the correctness of the packages by checking the gpg signature (the *.asc files) that come with the packages. Like this for instance:
Get the Slackware GPG key and import that into your keyring:
gpg --import GPG-KEY
and then proceed to verifying the packages' integrity:
for i in `ls *.tgz` ; do gpg --verify $i.asc ; done
You can upgrade your existing installation by preferably dropping to single-user mode. This is safest but not an absolute requirement - in single use mode, only a reduced number of programs are active and especially, the network is down so no-one can hack you while you0re vulnerable in the middle of upgrading:
And then rebooting or going back to your original runlevel by running
Your previuos runlevel might have been "4" if you boot directly into the KDM graphical login manager, in that case change the "3" in the above telinit command to "4".
A good way to find out your previous runlevel is to run the command
It will show you two numbers, the previous
runlevel followed by the current
The same procedure is valid for Slackware 10.2, since there have been many security updates to that as well. It is wise to follow the updates to a release closely by subscribing to the Slackware security mailing list
Upgrading to a new release does mean downloading all of the new release. There is no other way to go from Slackware 10.1 to 10.2 because by installing security updates you only keep your currently installed Slackware safe. Read the Slackware 10.2 UPGRADE.TXT, like here: http://slackware.mirrors.tds.net/pub....2/UPGRADE.TXT
if you want to learn more about the upgrade process. Also, this link
is a good read if you want to upgrade.
