Microsoft to patch zero-day bug Tuesday

The zero-day attack identified by FireEye as a vulnerability in Internet Explorer will, apparently by happy coincidence, be patched Tuesday as part of Microsoft's regular monthly updates.

Over the weekend, security company FireEye reported an unpatched vulnerability in Internet Explorer which was being used in a targeted zero-day attack against users of a particular web site.


Today, Microsoft announced that the vulnerability will be patched Tuesday in one of their already-scheduled updates. Microsoft says the vulnerability, which has been given the ID CVE-2013-3918, affects an Internet Explorer ActiveX control, but the update that will fix it, Bulletin 3 or MS13-090, is identified as an update to Windows.

Microsoft identifies mitigation techniques, but under the circumstances (highly-targeted attack, patched tomorrow) it's probably not worth resorting to them.
