Today, in keeping with its usual schedule, Microsoft released the Security Bulletin Advanced Notification for October 2013, previewing the security bulletins and associated patches it intends to release on Tuesday, October 8, 2013. This month there are eight bulletins in all; four of these have a maximum security rating of Critical; the others are rated Important. Four of the bulletins affect Windows and its components. Three bulletins affect Microsoft Office (including Office for Mac); one of these also affects Microsoft’s SharePoint server. A final bulletin affects Microsoft’s Silverlight. More details on specific versions are given in the Advanced Notification.
All supported desktop versions of Windows have at least one Critical bulletin. The table below shows a breakdown of the Windows bulletins by severity and Windows version.
| Windows Version | Critical | Important | Moderate |
|---|---|---|---|
| Windows XP+SP3 | 4 | — | — |
| Windows Vista | 4 | — | — |
| Windows Server 2003 | 3 | — | 1 |
| Windows Server 2008 | 3 | — | 1 |
| Windows 7 | 4 | — | — |

The bulletins for Office and Slverlight are rated Important.
Microsoft says that three of the bulletins will definitely require a restart, and the other bulletins may require one, depending on your system’s configuration.
As always, this information is subject to change between now and the actual release of the bulletins on Tuesday. If there are significant changes, I will post a note here once the actual updates are available.
