Microsoft has said it will deliver a record-equalling 13 security updates next Tuesday to patch more than two dozen vulnerabilities in Windows and Office. The company will ship a total of 13 updates next week; five of them pegged “critical,” the highest threat ranking in its four-step scoring system.
The 13 updates will, according to ComputerWorld, tie the record from October 2009, when Microsoft issued the same number of bulletins, but fixed a total of 34 vulnerabilities. According to Jerry Bryant, a senior manager with the Microsoft Security Response Center (MSRC), next week’s updates will patch 26 flaws.
Of the eight updates not marked critical, seven were ranked “important,” the next-lower rating, while one was pegged “moderate.” Eleven of the 13 will affect one or more editions of Windows; the remaining pair will affect Office XP and Office 2003 on Windows, and Office 2004 for Mac.
Server 2008 R2 will be affected by five of the 11 Windows updates. Windows 7, the newest client operating system, will be impacted by the same percentage, 45%, of the total. The eight-year-old Windows XP, meanwhile, will require eight of the 11, or 73% of Windows updates, while the even older Windows 2000 will be affected by 9 of the 11, or 82% of the total.
