As summer comes upon us in the Northern hemisphere, June is again one of the heavier months for Microsoft. For 2009, it was 10 Advisories, covering 31 Vulnerabilities. For June 2010, Microsoft has announced 10 Advisories, with 34 Vulnerabilities covered.
For Windows, 2 Critical and 4 Important are listed. For Office, 2 rated as Important. Another Important Advisory affects both Windows and Office. And the last Advisory is Critical and affects Internet Explorer.
6 Advisories may lead to Remote Code Execution, 3 may lead to Privilege Escalation and one may lead to Tampering. 2 require a restart and the other 8 may require a restart.
Josh Abraham, one of our Security Researchers here at Rapid7 commented: "There was a huge amount of vulnerabilities listed for Office today! One of the bulletins had 16 vulnerabilities. It is important to keep in-mind the perspective of the attacker when prioritizing the remediation efforts. The exploitability of the vulnerabilities is very high so customers should watch out for exploits in the near future."
"Another month with KillBits and Media vulnerabilities! Both of these should be at the top of the list for remediation. The interesting thing about the Kill bits issue is that it was not included in the exploitability rankings, but it affects IE8 developer tools, Microsoft Data Analyzer and a few Third-Parties."
Josh also slipped MS10-035 a bit farther down his patch list. "I think people should be patching the media decompression vulnerability first," he said, referring to MS10-033. "I'd put the IE update directly following that."
MS10-033 contains fixes for two vulnerabilities, both critical, that affect every supported operating system in Microsoft's portfolio, including the newest, Windows 7. Microsoft said that DirectX, the Windows media runtime, the encoder and a COM component all contain bugs. "This is more of the usual," said Abraham, talking about MS10-033, "where attackers can leverage client software using drive-by downloads."
Here’s a breakdown:
MS10-033: Rated Critical. Potential Remote Code Execution in Windows covering 2 vulnerabilities - CVE-2010-1879 (Media Decompression Vulnerability) and CVE-2010-1880 (MJPEG Media Decompression Vulnerability).
