Microsoft is poised to break its record for the most Patch Tuesday security bulletins ever for the second time in 2010.
On Oct. 12, the company is set to release 16 security bulletins to cover a total of 49 vulnerabilities in Windows, Internet Explorer, Microsoft Office and the .NET framework. In August, the company set a new record with 14 bulletins. That update fixed 34 security holes across a number of products.
This time around, four of the bulletins are rated critical, while 10 are ranked as important and two others are considered moderate. All of the critical bulletins address vulnerabilities that could be exploited to permit remote code execution.
In addition to the upcoming fixes, administrators will need to look at deploying the out-of-band bulletin released the week of Sept. 27 as well as Adobe Systems' recent updates if they haven't done so, said Jason Miller, data and security team leader at Shavlik Technologies.
"This month will be particularly challenging for administrators as most patch scenarios will hit every machine on a network," Miller said.
The 16 bulletins would bring the total for the year to 86 for Microsoft.
