Why is it that people are always touting the supposid instability and security-flawed nature of Microsoft products, but then go silent when OS-X or dare I say it Linux, reveal holes?

Today, from CNET:

The patch fixes software flaws that could enable an attacker to crash or freeze the Apache 2 Web server, run software by utilizing Apple's Safari Web browser or expose the password store used by the network. Security information provider Secunia ranked the Kerberos threat as "highly critical," its second-highest danger rating.

Typically, Apple has just talked about it's fixes to security flaws and patches as minor updates. At least now it is being a bit more open about it. I guess with Linux, you can just download the patches for whatever myriad version you're running from some site and just recompile the kernel. Sounds secure to me.
