Overview of the June 2012 Microsoft patches and their status.

# Affected Contra Indications - KB Known Exploits Microsoft rating(**) ISC rating(*)
clients servers
MS12‚??036 RDP (Remote Desktop Protocol) allows random code execution due to input validation issues. Also affects Small Business Server 2003 (called "Remote Web Workplace"). Having exposure to the RDP port with a vulnerable version on e.g. your web server will put you at great risk.
Remote Desktop

KB 2685939 No publicly known exploits. Severity:Critical
Important Critical
MS12‚??037 The usual MSIE cumulative patch fixing a multitude of security vulenrabilities, you want this one!
Note: this bulletin shares a CVE-2012-1858 with MS12-039 (both Internet Explorer and Lync suffer from the same)
Replaces MS12-023.

KB 2699988 CVE-2012-1875 has active exploits against it according to the bulletin. Severity:Critical
PATCH NOW Important
MS12‚??038 An vulnerability in .NET framework allows random code execution with the rights of the logged on user. This not only affects users browsing websites but also servers running .NET applications as they could bypass Code Access Security (CAS) restrictions.

KB 2706726 No publicly known exploits Severity:Critical
Critical Critical
MS12‚??039 Multiple vulnerabilities in Lync allow for random code execution and information leaks.
CVE-2012-3402 is also affecting other Microsoft software (true-type font parsing).
CVE-2012-1858 is also affecting MSIE (HTML sanitation issue).
CVE-2012-1849 is related to the loading of libraries problems affecting many Microsoft products, first described in SA 2269637.

KB 2707956
No publicly known exploits, but most vulnerabilities are quite well known due to exposure in other Microsoft products Severity:Important
Critical Important
MS12‚??040 A XSS vulnerability in Microsoft Dynamics AX Enterprise Portal.
Microsoft Dynamics AX Enterprise portal

KB 2709100
No publicly known exploits Severity:Important
N/A Important
MS12‚??041 Multiple vulnerabilities in the windows kernel mode drivers allow escalation of privileges.
Replaces MS12-018.
Windows kernel mode drivers

KB 2709162
No publicly known exploits Severity:Important
Important Important
MS12‚??042 Multiple vulnerabilities in the windows kernel allow escalation of privileges.
Replaces MS11-098 and MS11-068.
Windows kernel mode drivers

KB 2711167
CVE-2012-1515 was publicly disclosed. No publicly known exploits Severity:Important
Important Important
We will update issues on this page for about a week or so as they evolve.
We appreciate updates
US based customers can call Microsoft for free patch related support on 1-866-PCSAFETY
(*): ISC rating
  • We use 4 levels:
    • PATCH NOW: Typically used where we see immediate danger of exploitation. Typical environments will want to deploy these patches ASAP. Workarounds are typically not accepted by users or are not possible. This rating is often used when typical deployments make it vulnerable and exploits are being used or easy to obtain or make.
    • Critical: Anything that needs little to become "interesting" for the dark side. Best approach is to test and deploy ASAP. Workarounds can give more time to test.
    • Important: Things where more testing and other measures can help.
    • Less Urgent: Typically we expect the impact if left unpatched to be not that big a deal in the short term. Do not forget them however.
  • The difference between the client and server rating is based on how you use the affected machine. We take into account the typical client and server deployment in the usage of the machine and the common measures people typically have in place already. Measures we presume are simple best practices for servers such as not using outlook, MSIE, word etc. to do traditional office or leisure work.
  • The rating is not a risk analysis as such. It is a rating of importance of the vulnerability and the perceived or even predicted threat for affected systems. The rating does not account for the number of affected systems there are. It is for an affected system in a typical worst-case role.
  • Only the organization itself is in a position to do a full risk analysis involving the presence (or lack of) affected systems, the actually implemented measures, the impact on their operation and the value of the assets involved.
  • All patches released by a vendor are important enough to have a close look if you use the affected systems. There is little incentive for vendors to publicize patches that do not have some form of risk to them.

(**): The exploitability rating we show is the worst of them all due to the too large number of ratings Microsoft assigns to some of the patches.

I'm intrigued by one of the vulnerabilities addressed in MS12-042, "BIOS ROM Corruption Vulnerability". I wonder if the possibility of BIOS malware (rare but not unknown) is perhaps a little larger on some radar screens with it. Most people I mention it to don't seem to take it very seriously.
Interestingly enough, CVE-2012-1515 maps to a VMware vulnerability, more on that here: According to the advisory, a ROM overwrite can result in privilege escalation on Windows based virtual machines. I guess both VMware and Microsoft are covering all bases here.
The Dutch page refers to a BIOS rootkit found by McAfee, described here (in English):

From e.b.'s comment we now know that not only _physical_ BIOS memory is at risk!
A Dutch site states that this is the same hole as patched in MS12-020, reopened by a SP. Is this correct?
An automatic updater of revoked certificates is available for Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2
