The vulnerabilities were reported in online security forums on Monday, according to a posting on the McAfee Avert Labs blog on Tuesday. All but one of the flaws results in denial of service, meaning the application would crash, according to the blog post.
Though a mere crash isn't much in the big picture, another flaw has the potential for arbitrary code execution. Not all of the flaws may be newly discovered, and may simply be rehashes of what is already known. Either way, it leaves several unpatched flaws in the Office suite and has brought them to light.
