Microsoft has announced plans to release nine security bulletins to patch 21 vulnerabilities on February 14.

"The first four bulletins are rated critical, the highest rating the firm uses, and all relate to remote code execution," writes The Inquirer's Chris Martin. "The remaining five bulletins are graded as important, the second highest rank, three of which also relate to remote code execution."

"Nine bulletins mean it's got two more than January's raft of seven bulletins," Martin writes.
