(*): 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

We have been getting reports of people having issues applying MS11-003 (see comments).  No doubt you are testing this in a test environment first anyway, but for this patch you may wish to double check.  Errors of invalid hash and error code 0x80246002.  

If you do have issues with your patches make sure you let Microsoft know via your support channel.

The patching fun for the week continues with WordPress releasing an update. 

This release is shown as a security release and contains a number of fixes for security issues. WordPress is one of the favourite targets, so all are encouraged to upgrade and get the benefits of the security fixes included (make sure you test before throwing it into production).

Tippingpoint Releases Details on Unpatched Bugs

Published: 2011-02-08

Tippingpoint, which operated the "Zero Day Initiative" bug bounty program released 22 vulnerabilities for which no patch is available [1]. Last year, Tippingpoint announced that they will release details 180 days after they are aware of a bug, even if the vendor has not yet released a patch.

The details released include a one paragraph description of the vulnerability, which in itself is usually not enough to come up with an exploit, but it may provide a pointer to re-discover the vulnerability.

Snort is coming out Thursday, ClamAV 0.97 update released

While this post may be a bit self-serving, as Snort is made by the company that I work for (Sourcefire.  In the interest of full disclosure).   Since Snort is rather large piece of security software, I thought I'd point to a blog post that I put up on the Snort.org blog about the release of Snort that is being release this Thursday.

Check out the Snort blog post here.  

ClamAV was also updated this week to version 0.97, and since this a rather large piece of security software as well, I thought I'd point to the blog post that I wrote about ClamAV 0.97 update the other day.

Thanks all.

Adobe released updates for Reader for 9.4.2 and 10.0.1.  While this page on Adobe's site doesn't actually list them correctly, if you drill down into the actual product and OS, you'll see the updates listed for 2/8/2011.

Happy Patching.
