# | Affected | Contra Indications - KB | Known Exploits | Microsoft rating(**) | ISC rating(*) | |
---|---|---|---|---|---|---|
clients | servers | |||||
MS13-021 |
The usual MSIE cumulative patch, adding fixes for eight more vulnerabilities. All 8 are of the "use after free" type and they all allow random code execution. Replaces MS13-009. |
|||||
MSIE CVE-2013-0087 CVE-2013-0088 CVE-2013-0089 CVE-2013-0090 CVE-2013-0091 CVE-2013-0092 CVE-2013-0093 CVE-2013-0094 CVE-2013-1288 |
KB 2809289 | CVE-2013-1288 was made public according to Microsoft. |
Severity:Critical Exploitability:1 |
Critical | Important | |
MS13-022 |
A double dereference vulnerability that allows random code execution in Silverlight. This also affects the mac version of silverlight 5. The update is expected via the auto-update feature on Macs. Replaces MS12-034. |
|||||
Silverlight CVE-2013-0074 |
KB 2814124 | No publicly known exploits |
Severity:Critical Exploitability:1 |
Critical | Important | |
MS13-023 |
A memory management vulnerability allow random code execution in the Visio viewer. The full package is exempt from this problem. Replaces MS12-059. |
|||||
Visio Viewer CVE-2013-0079 |
KB 2801261 | No publicly known exploits |
Severity:Critical Exploitability:2 |
Critical | Important | |
MS13-024 |
Four different privilege escalation vulnerabilities in Sharepoint. Of note: it includes an XSS and a directory traversal vulnerability in addition to a problem with callback functions and a buffer overflow. Replaces MS12-066. |
|||||
Sharepoint CVE-2013-0080 CVE-2013-0083 CVE-2013-0084 CVE-2013-0085 |
KB 2780176 | No publicly known exploits. |
Severity:Critical Exploitability:1 |
N/A | Critical | |
MS13-025 | A buffer management problem allows leaking arbitrary data in memory. It could expose usernames and passwords of accounts. | |||||
OneNote CVE-2013-0086 |
KB 2816264 | No publicly known exploits. |
Severity:Important Exploitability:3 |
Important | Less Urgent | |
MS13-026 |
When previewing or opening an email that contain HTML5, outlook for Mac can load content from random webservers without user interaction. The note is quite confusing. E.g.: every mac capable of running the affected versions has a webkit browser installed together with the OS; Office for Mac 2008 did not have outlook - it had entourage instead; Outlook isn't part of all Office for Mac 2011 licenses either. Replaces MS12-076. |
|||||
Outlook for Mac CVE-2013-0095 |
KB 2813682 | No publicly known exploits |
Severity:Important Exploitability:3 |
Less Urgent | Less Urgent | |
MS13-027 | 3 similar problems exist with the windows USB drivers that allow privilege escalation to full administrative rights. | |||||
USB Kernel Mode Drivers CVE-2013-1285 CVE-2013-1286 CVE-2013-1287 |
KB 2807986 | No publicly known exploits |
Severity:Important Exploitability:1 |
Important | Less Urgent |

(*): 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.

Helped to resolve an unusual and puzzling network connectivity issue related to DirectAccess (kb2680464) and really slow logon due to poor GPO processing performance.
YMMV, as we're testing....

I can verify that MS13-027 is detected as vulnerable and was patched using my Lumension patch server.

Manual Updates in Win7 x64 are still broken in that you must navigate to 'Important', check the box and choose to install.
I am copying from a reply to a responder at another site a few minutes ago. MS appears to be trying to fix this as WinXP on at least one machine is now installing via 'Automatic Updates'.
Copy of current state of patching:
I just logged into my WinXP Pro test box that was not picking up KB2807986 yesterday and was greeted with an 'updates are available' icon in the system tray.
KB2807986 was the only new patch listed since yesterday's patch install/reboot.
Status: WinXp Pro appears to be fixed. (I will verify on a second WinXP Pro machine in a few minutes.)
Win7 Pro x64...
A system that 'auto patched' last night did not install KB2807986.
A 2nd system that had been set to download and notify also did not receive KB2807986.
On both of these systems, despite reboots and choosing 'check for updates' via Control Panel>Windows Updates, the patch is still listed under 'important updates', is unchecked and does not get installed without user intervention.
Status: Win7 Pro x64 is still not flagged correctly for forcing this installation automatically.
