number of them, maybe that's something to think about, but I see 2 in
2012, and 5 in 2013, and 0 in 2014... and those are not really the
biggest issues in the world either, and certainly not in any way
relevant if you just leave the files lying around....
Past performance does not indicate future pains. It doesn't matter if an application even have had 0 in the past.. the idea of having to respin every image because of a piece of software which isn't needed but is included in everything will cause the bristles go up for any large organization that must pass audits. (or a company that hosts for companies that must pass audits). It doesn't matter that it can't be used to break out of the image etc.. it is more about potential work and what can cause that potential work.
[This is non-rational but is how things work and after twenty years of telling people that putting antivirus on a linux desktop doesn't solve a problem... it isn't the sort of problem which goes away with a rational argument.]
