Next week's edition of Patch Tuesday will deliver 17 security bulletins that will fix a total of 64 different vulnerabilities in Microsoft's software. Nine bulletins are rated as "critical" and the rest received an "important" rating.
As well as the typical patches for Windows, Internet Explorer, and Office, a couple of the bulletins include more unusual patches. Specifically, the Office Web Apps and Visual Studio are both receiving fixes this month. Not included in the list of patched software is Internet Explorer 9; this latest browser version is apparently immune to the flaws affecting versions 6, 7, and 8 that will be patched next week.
Microsoft has also confirmed that these patches include fixes for the MHTML flaw publicly disclosed in January, and an SMB flaw disclosed in February. In March, the company announced that it had learned of limited, targeted attacks using the MHTML flaw. The SMB flaw carried a theoretical possibility of remote code execution, but the company felt that denial of service was the more likely outcome. As ever, the full list of resolved flaws won't be announced until next week.
