Microsoft will issue a patch for a "critical" security flaw in Windows, the company said Thursday. The patch comes outside of its normal monthly patching cycle due to the severity of the issue.
The vulnerability can result in a remote code execution, in which malicious attackers could take control of a user's computer to launch code.
Microsoft will hold a Webcast at 1 p.m. PDT to address the issue.
Issuing patches outside of its monthly cycle is rare for Microsoft. The last time it happened was April 2007, according to a Microsoft representative.
