It's a serious issue, yes.
However, the way it's reported via the media, for example, the BBC News website, is a bit misleading for your average "Joe" who knows little about PC's.
There's nothing in the report making it clear that a user would actually have to visit a "malicious" website which is exploiting this flaw in order to put their system at risk from this vulnerability. There's a bit of a confusing mish-mash of info near the end of that BBC report which mentions websites that offer programs that steal computer game passwords but for the average punter off the street, that means diddly squat to them.
Yes, it's a serious issue but scaremongering by way of misinformation via the media really doesn't help anyone.
Basically what the BBC report is saying is "Switch browsers or your doomed!!!".
Switching browsers of course is a sensible option to take, but I've already had 4 people call me this morning saying "OMG....!!!! Have you heard?. Don't use IE today, hurry.....!!!!......switch browsers to a thing called Firefox, the BBC says you must...!!!!".
All a bit of a drama out of a crisis to be honest.
