According to the Microsoft Security Response Center, Microsoft will issue 10 Security Bulletins addressing 34 vulnerabilities on Tuesday. It will also host a webcast to address customer questions about the bulletins the following day.
Three of the vulnerabilities are rated "Critical" and seven are marked "Important." All of the Critical vulnerabilities earned their rating through a remote code execution impact, meaning a hacker could potentially gain control of an infected machine. At least two of the 10 patches will require a restart.
