August Windows Updates critical, require reboot

It has been too long since I posted here.  Microsoft's July update cycle was a small one with only one critical patch affecting Windows Vista/7 users, so I didn't bother blogging about it. However, the August patch set is much larger -- two critical patches including one for Internet Explorer which Microsoft says is likely to be exploited soon. The updates for M$ Windows and Microsoft Office require a reboot. Combine that with a surprise release of new versions of Adobe Flash Player and Adobe Shockwave Player and system admins are going to be busy this week.

Microsoft expecting exploits for critical IE vulnerabilities | ZDNet
By Ryan Naraine | August 9, 2011, 12:11pm PDT

Microsoft today warned that multiple gaping security holes in its Internet Explorer browser could expose millions of Web surfers to hacker attacks via rigged web pages.

As part of this months’ Patch Tuesday release, Microsoft shipped a “critical” IE bulletin (MS11-057) with fixes for total of 7 security flaws. Two of the vulnerabilities were publicly discussed prior to the availability of the patch.

The company expects to see reliable exploits developed within the next 30 days.

Because these vulnerabilities expose IE and Windows users to drive-by download attacks without any user action beyond surfing to a booby-trapped web site, Microsoft is strongly recommending that all Windows users apply the patch immediately.

The IE update is rated “critical” for Internet Explorer 6 on Windows clients, and for Internet Explorer 7, Internet Explorer 8, and Internet Explorer 9; and Important for Internet Explorer 6 on Windows servers.
