Slashdot is noting that Microsoft Patches VML Vulnerability. “Microsoft has quietly released an official patch for the zero-day VML vulnerability. The patch was publicly available yesterday, But Microsoft has just added it to the Security Bulletin Index.” Eight days from time of first report to patch is pretty fast for Microsoft, and is almost two weeks ahead of their normal patch schedule. This security flaw was being aggressively exploited out in the wild.”
For Microsoft to break their usual once-a-month patch cycle is pretty unusual, so I'd consider this patch sooner rather than later. Get patching!
