Microsoft: five disclosed flaws likely exploited next month

August Patch Tuesday fixes seven IE flaws.

Microsoft has released 13 security updates for its August Patch Tuesday update, five of which it considered likely to see reliable exploits developed for within the next 30 days.

The first bugs it expected to see exploited were critical Internet Explorer flaws (MS11-057) that could allow an attack to infect a system when the victim browsed a rigged web page.

Microsoft recommended enterprise customers update immediately. The IE update update fixes five privately reported vulnerabilities and two publicly disclosed ones, it said. 

The other critical update related to its web address identification system, DNS Service.

“This vulnerability affects DNS servers that allow attackers to issue lookup requests for another domain name in a way that would cause the DNS server to request the answer from a malicious DNS server,” it explained.

The flaw was unlikely to be exploited, but DNS servers connected to a corporate network as a cache or relay service were more vulnerable than internet-facing servers, according to Microsoft.

Other flaws likely to be exploited in the next month included a Windows elevation of privilege vulnerability, a flaw in its diagram program, Visio, and a cross site scripting (XSS) flaw in its Remote Desktop Web Access Login Page.
