(*): 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

Adobe Flash v10.1.82.76 and earlier vulnerability in-the-wild

Adobe has released an advisory for Flash Player 10.1.82.76 and earlier versions for Windows, Macintosh, Linux, Solaris, and Adobe Flash Player 10.1.92.10 for Android, as well as Adobe Reader 9.3.4 for Windows, Macintosh and UNIX, and Adobe Acrobat 9.3.4 and earlier versions for Windows and Macintosh. CVE-2010-2884 has been assigned to the issue, which has an impact of crashing Flash or arbitrary code execution on some affected platforms. There is currently no patch, Adobe has indicated that it should be released in late September and/or early October. There are indications that this previously unknown vulnerability is currently being exploited in the wild by malicious web sites attacking browsers. YYAAAV Yes, Yet Again Another Adobe Vulnerability. Sigh.

Keep an eye out for this one folks. It will take a bit for the anti-virus, IDS/IPS and other vendors to catch up and detect the malware that exploits the vulnerability. Although by that point the box affected may well be compromised as most detect after the exploit has already taken place. Since the vendor has released the advisory after being notified that exploits are already occurring against Windows boxes it is recommended to explore workarounds for mitigation, detection of already compromised hosts, and cleanup.

Shadowserver has published their take on a recent series of DDoS attacks http://www.shadowserver.org/wiki/pmwiki.php/Calendar/20100913. The control domains, victim industries, countries affected, and command communications are all listed in the article. Not a complete analysis of the BlackEnergy bot, and bots are not a new phenomenon, but server to remind that DDoS for hire is still around, botnets are still around, and that their impact can be devastating.
