Overview of the June 2008 Microsoft patches and their status.
|#||Affected||Contra Indications||Known Exploits||Microsoft rating||ISC rating(*)|
|MS08-030||A vulnerabilities in the Bluetooth stack allows code execution when a large number of SDP (Service Discover Protocol) requests are made.|
|KB 951376||No publicly known exploits||Critical||Critical||Important|
|MS08-031||Multiple vulnerabilities in MSIE allow code execution and cross domain information leaks. The memory corruption gives access to the same rights as the logged-on user has. The vulnerability in parsing headers allows for HTTP Request Splitting, HTTP Request Smuggling and more (See CVE-2008-1544 for more details).
||Details on attacking CVE-2008-1544 are publicly available||Critical||PATCH NOW||Important|
A vulnerability in the Speech API accepts commands sent to it over the speakers of the computer, allowing an attacker access to the same rights as the user has. The speach recognition must be enabled for this to work.
|ActiveX Kill Bits
|KB 950760||Publicly discussed||Moderate||Important||Less Urgent|
Multiple input validation vulnerabilities allow code execution in DirectX. Affected are MPEG streams in ASF and AVI files and parameters of SAMI (Synchronized Accessible Media Interchange) files.
||No publicly known exploits||Critical||Critical||Important|
Privilege escalation vulnerability in WINS allows an attacker to gain complete control of a vulnerable system by sending crafted packets to the WINS server.
||No publicly known exploits||Important||Less Urgent||Critical|
Input validation failure in the LDAP implementation part of AD leads to a Denial of Service.
|KB 953235||No publicly known exploits||Important||Less Urgent||Critical|
Multiple input validation failures in the PGM packets allow a Denial of Service. PGM is active when MSMQ (Microsoft Message Queuing) is installed on a system.
|PGM (Pragmatic General Multicast)
|KB 950762||No publicly known exploits||Important||Important||Important|

- 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.
