Microsoft  regard ship 13 bug patches in next week’s “Patch Tuesday” drop down — eight of them rated “critical” — the society about severe surety grading.

Of those, seven fix problems in Windows, according to Microsoft’s advance notice sent out Thursday.

Tuesday as well acquits an instead doubtful differentiation: them leave fix the largest number of security holes ever, beating out June’s Patch Tuesday record of 31 holes fixed.

Overall, the 13 patches coming Tuesday fix a total of 34 holes in the company’s software, according to a post on the Microsoft’s Security Response Center (MSRC) Team blog Thursday.

Microsoft brings out about flecks as it has intersections along a fixture monthly cycle, on the second Tuesday of the month, thus the name “Patch Tuesday.”

Beyond the record, what might cost nearly significant about Tuesday’s patch release are patches to block two zero-day holes that have been nagging the company for more than a month.

For one, the patches aim to fix a vulnerability in Windows’ implementation of the popular File Transfer Protocol (FTP) that was discovered in early September.

A second piece leave fix a different zero-day fix ascertained a few days later. It involves Microsoft’s implementation of the System Message Block version 2 file sharing protocol, referred to as SMB2.

While Microsoft accepts came out workarounds as some troubles, the only completely safe options are to disable or block both protocols. That can be problematic, however, as they generally disable functions some users rely on.

“Generally we act not belong into this level of detail in the approach notice merely we experienced that they are crucial counsel and so buyers could design consequently and deploy these updates as soon as possible,” the blog post said.

Microsoft seldom acquittances data during a bug till an spot is usable, so the further acknowledges arrange not carry a lot more detailed information about specifically what will be fixed on Patch Tuesday.

These time, the array by controlling schemes adaptations involved stretches from Windows 2000 Service Pack (SP) 4 through Windows XP and Windows Vista, as well as Windows Server 2003 up through Server 2008 Release 2 — although not all patches affect all versions.

One patch also affects Windows 7 running Internet Explorer 8.
