How much of what's on that list actually applies to a recent version of Wordpress?
Saying recent here isn't logical, because after patching the incident, it's not an incident anymore. But I guess you mean how secure you are with a recent version of Wordpress. I think this is though question, because Wordpress relies to a high degree on external components and plugins. There is probably no single pure Wordpress Blog, because the original Wordpress archive already relies heavily on external dependencies. That's where many of the issues were found as correctly pointed out by wyck. However this reliance on external code, without a Wordpress team or at least a software that is evaluating the code-quality or any other metric, you can't be secure. Yeah we can argue with: "But Wordpress is n-times more popular than X." However it still makes WP very vulnerable to attacks. I've cleaned and recovered some hacked commercial wp blogs and shops myself (not installed by me, but the previous dev). So whatever you believe in WP may be, just get over it. There are so many other opensource alternatives that wait for you to be tried out.
Without exaggerating, I've downloaded almost any CMS on Github and Bitbucket and Sourceforge and I'm almost done with testing all of them. I think about 15 remain. With all honesty, I cannot say that I'm impressed with any CMS so far. There is just one thing that stood out, with it's concept, but it's still only Alpha grade quality, that's: http://parsimony.mobi/
I've you're curious what I ended up with, just ping me and I'll share my results, after I've really compared all CMS with each other. Currently I would say that there are about ~10 good quality CMS, with hundreds of miserably coded ones. That is a good benchmark, for how good developers are in the real world, I mean there is only so much space at the top of the iceberg. Not everybody can excel with every project they start (well, except people like Fabrice Bellard)
I've not compared Typo3, Alfresco and other Enterprise CMS, because even when they come with all features loaded, they suck at code complexity and user friendliness
You can't tell me that Wordpress is the only blogging platform that fits to all of your requirements, because there are thousands of CMS out there and you'll spend weeks testing all of them.
