Microsoft’s Valentine’s Day bulletin to include nine patches addressing 21 vulnerabilities

Microsoft may not be able to patch that hole in admins’ hearts on Tuesday, but it will take care of a number of other vulnerable spots.

According to an advance notice, the company’s next security bulletin will include nine patches, four of which are labeled ‘critical,’ addressing 21 vulnerabilities in Windows, Windows Server, Microsoft Office, Internet Explorer and .NET and Silverlight.

Windows Server 2008 and Windows Server 2008 R2 are the most affected products, with six bulletins applying to each, including three critical updates. In contrast, only four bulletins apply to Windows Server 2003, two of which are critical. Five bulletins apply to Windows 7.

All critical updates are related to remote code execution flaws, with the most pressing fixing an issue in Internet Explorer. Most patches will require a restart. The bulletins will be released on Tuesday, February 14 around 1 p.m. EST.
