The flaw we heard about a few days ago regarding XML Core Services will be patched by Microsoft during the monthly patching cycle. Even though the scope of the flaw is fairly low, it is serious enough to earn a “critical” rating, along with 5 other fixes that are planned for this release. The flaw was discovered just a few days ago, and doesn't affect home users of Windows, targeting only Windows Server 2003 in specific configurations. Secunia reported on the vulnerability, saying that it is being actively exploited by hackers. Even though it is of that serious a nature, Microsoft still is committed only to releasing patches on their set date.
