We appreciate updates
US based customers can call Microsoft for free patch related support on 1-866-PCSAFETY
- 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.
(**): Mainly due to shared webservers being very affected by this
(***): Mainly due to classic ASP being used on many web servers like shared hosting providers

Stormworms spammy love notes
We received several reports of spam containing Subject lines such as: “Sweetest Things Aren’t Things!, Valentine’s Day, The Love Train” and other similar subject lines. These all included a URL that just an IP Address. Those URLs lead to binaries named valentine.exe. The MD5 on the binaries is changing rapidly so AV detection based on MD5 or other hash values is not reliable.
We submitted one version to virustotal. 12/31 of the av engines there recognized it. Valentine.exe is a new version of storm worm. Thanks to contributors Doug, Colin, Susan.
Update: The URLs are now being hosted on fast flux style hosting. Domains seen so far include destroythemoon.com and moonstarfood.com. Subject lines now also include "I Love You, Rockin' Valentine, You Stay in My Heart, My Heart For You, A hearty WIsh, and Thinking of U All Day". I am sure we will see other subject lines.
Jose Nazario of Arbornetworks has some additional about this at: http://asert.arbornetworks.com/2008/02/new-storm-valentines-day-campaign/

Apple security update 2008-001 and 10.5.2 upgrade
Apple released today a Security Update 2008-001 for MacOS X 10.4 fixing 5 vulnerabilities in one patch.
At the same time an upgrade to Mac OS X 10.5.2 was released, which also incorporates the security update all in one package (fixing 8 vulnerabilities). An upgrade like this can be best compared to a Service Pack in the windows world. It's not just a security fix, but also a functionality upgrade.
- Mac OS X 10.5.2:
http://docs.info.apple.com/article.html?artnum=307109 - Security content of 10.5.2 and security update 2008-001:
http://docs.info.apple.com/article.html?artnum=307430 - As always Apple updates can be found on:
http://docs.info.apple.com/article.html?artnum=61798
As always, Apple packages security fixes into one big patch. Software update will offer it to your mac users that haven't turned the feature off.

RIM Blackberry outage
A number of readers have contacted us about the current RIM Blackberry outage. It would appear that this is affecting a large number of Blackberry users in the US. Although this is not a security posting, we do understand that a lot of security and system admin staff are attached to their Blackberry so its time to hold together fellow admins until the e-mails start flowing.
There is a useful RSS newsfeed about the Blackberry service here: feeds.feedburner.com/Bb-outage
