My two cents are that by Symantec posting this information, it can cause people to think "man, they're on top of it since they're the ones who found this out." Throw in the comment about definitions being up to date, you think anti virus and as it is an anti virus company posting this information, if you're in the market for an AV program it might influence you to go with them since the fact that they caught this makes them look good. So posting this is a good marketing tool, even if it is an indirect one. The sad thing though, is that if they hadn't put this up and instead two months down the road mentioned in passing that they had found this information out two months earlier . . . Well, then they would be blasted for not mentioning it as opposed to being blasted for mentioning it in what is seen as an attempt to make them look good. The fact that they did put it up on a Symantec blog on a Symantec website that would largely only be seen by existing Symantec customers (until someone posts it on another website that is ) does lessen the impression it's an ad for their product just a little.
