July's Patch Tuesday fixes 6 critical Microsoft flaws

Microsoft has released its Patch Tuesday for July. It consists of seven bulletins, six of them critical, that, if exploited, can give attackers power to execute code on victim machines and control them remotely and one - important.

The critical security bulletins affect Windows, Internet Explorer, Microsoft Office, Silverlight, and more. The important security bulletin addresses a privilege elevation flaw in the Windows Defender security software, so that definitely shouldn't be ignored.

Altogether three of the bulletins patched flaws roughly matching the profile of the Windows kernel security issue that Google's Tavis Ormandy disclosed back in May (CVE-2013-3660).

Of the critical security bulletins, three address a vulnerability in how Microsoft software renders fonts. The most likely way of being attacked is by browsing a malicious Web page or opening an infected document.

"Fonts have become really complicated," said Wolfgang Kandek, chief technology officer for compliance and security software company Qualys. "There is real processing going on when you print a character, and that complexity can be attacked."
