It is very important to speak precisely about these matters to avoid jumping to unfounded conclusions that lead to erroneous reactions. You said "virus attack" which is a mischaracterization of the problem. It was a vulnerability, only the potential for a man-in-the-middle attack which has absolutely nothing to do with viruses.
For your Mac to be attacked, it would have to be attempting an SSL connection with Safari or other related frameworks, and there would have to be another user on the same wifi network as yourself intercepting the transmissions and skilled enough in network coding to implement a man-in-the-middle attack. So users on school and public wifi networks using Safari were vulnerable, but home users on their own password-protected networks or Chrome/Firefox users were not particularly vulnerable.
From the articles on Mac sites that I read, which described all of the above, it was also said that only Mavericks was vulnerable. However, there were other security updates issued for Mountain Lion and Lion to address other issues.
10.5.8 along with 10.6 are no longer supported due to age and no longer receive security updates.
