(*): 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.

Adobe, Google and other Patch Tuesday patches

Adobe

Adobe published two advisories today:

(Correction: APSB13-25 was released last month, and I have removed it from this diary. Instead, APSB13-27 was added below)

APSB13-26: Security Updates for Flash Player

This update affects the Windows, OS X as well as the Linux version of Adobe Flash Player 11.9 (11.2 for Linux) , as well as Adobe Air 3.9. The Flashplayer vulnerability is assigned a priority of "1" on Windows and OS X which indicates an exploit has been sighted in the wild and Adobe recommends patch "as soon as possible" (72 hrs).

Vulnerabilities that are covered by this patch: CVE-2013-5329, CVE-2013-5330.

APSB13-27: Hotfix for Coldfusion

This hotfix affects Coldfusion 9 as well as 10. Adobe assigned it a priority of 1 for Coldfusion 10 and 2 for Coldfusion 9.x . The hotfix patches two vulnerabilities:

1 - A reflective XSS vulnerability in Coldfusion 9/10 (CVE-2013-5326)
2 - An authentication bypass problem in Coldfusion 10 (CVE-2013-5328)

The second vulnerability which allows unauthorized remote read access is probably the reason this hotfix is rated "1" for Coldfusion 10.

 

Google

Google released a new version of Chrome today: Chrome 31. The update includes 25 security fixes. Not exactly a security fix, but still interesting: Chrome 31 improves the SSL ciphers by adding support for the AES-GCM ciphers.
