Microsoft has released a major Critical Windows Security Flaw and fix. By critical, I mean they went outside of their normally rigid ‘patch Tuesday’ [twice a month] schedule and released this fix on-the-fly, so to speak.
“The flaw is in the way the Windows Adobe Type Manager Library handles OpenType fonts. In practical terms, if someone running Windows visits a website that contains embedded OpenType fonts or a specially crafted document, an attacker could execute code on his or her computer.
“An attacker who successfully exploited this vulnerability could take complete control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights,” Microsoft wrote in a security bulletin.”
The Windows update tool in modern Windows OS can handle this.
