Microsoft fixed a record number of vulnerabilities in its October Patch Tuesday. The company issued 16 bulletins to patch 49 separate vulnerabilities. All versions of Windows from Windows XP up to the latest versions, Windows 7 and Server 2008 R2, are affected. In addition, various security flaws in Microsoft Office were also fixed, as versions from Office XP to Office 2010 are affected. Four of the bulletins have been rated critical, two have been rated moderate, and the rest rated important.

The number of vulnerabilities in itself is noteworthy but two items from this crop of patches are especially notable. First of all, Mac users have something to worry about as well, as Office 2004 and 2008 and the OpenXML File Format Converter for Mac are covered by two bulletins. Server applications are also part of this month’s fixes, as several key components of the SharePoint collaboration suite have also been patched. Office Web Apps has also been covered.

October’s second Tuesday also coincides with Oracle’s own quarterly patching schedule. For its part, fixes for 81 separate vulnerabilities were issued. Most of these were for enterprise applications though some are for the open-source application suite, OpenOffice.

Enterprise users of Trend Micro products such as Deep Security and OfficeScan with Intrusion Defense Firewall (IDF) plug-in can use these to protect themselves until they complete deploying this month’s updates. Home users should visit the Windows Update site to download the patches as soon as possible.
