It’s June now so we get to look forward to the monthly Microsoft update, which will be next week June 8th.

These 10 bulletins will fix 34 vulnerabilities and MS will host a webcast on June 9 to address customer questions.

Three of the vulnerabilities are marked “Critical” and seven are marked “Important”. Critical vulnerabilities mean that they could be exploited to allow remote code execution allowing the hacker control of the computer. The operating systems included in this update are: Windows 2000, Windows XP (32-bit and 64-bit), Windows Server 2003 (32-bit and 64-bit), Windows Vista (32-bit and 64-bit), Windows Server 2008 (32-bit and 64-bit), Windows 7 (32-bit and 64-bit), and Windows Server 2008 R2.
