  • 22:46 Microsoft Security Advisory 971778 Vulnerability in Microsoft DirectShow Released
  • Weve just released Microsoft Security Advisory 971778 today. This discusses a new vulnerability in Microsoft DirectShow affecting Windows 2000, Windows XP and Windows Server 2003 that is under limited attack. The advisory outlines information about the vulnerability and steps customers can take to protect themselves while were working on a security update to address the issue.

     

    Our investigation has shown that the vulnerable code was removed as part of our work building Windows Vista. This means that Windows Vista and versions of Windows since Windows Vista (Windows Server 2008, Windows 7) are not vulnerable.

     

    The vulnerability is in the QuickTime parser in Microsoft DirectShow. An attacker would try and exploit the vulnerability by crafting a specially formed video file and then posting it on a website or sending it as an attachment in e-mail. While this isnt a browser vulnerability, because the vulnerability is in DirectShow, a browser-based vector is potentially accessible through any browser using media plug-ins that use DirectShow. Also, weve verified that it is possible to direct calls to DirectShow specifically, even if Apples QuickTime (which is not vulnerable) is installed.

     

    Our investigation has found three workarounds that you can implement to protect yourself and weve documented these in the security advisory.  In addition, weve got more technical details on the workarounds and the issue over at the Security Research and Defense (SRD) blog.

     

    Most importantly, we have found one workaround in particular that is simple and effective and protects against the vulnerability with limited impact. In fact, this particular workaround is simple enough that weve been able to give you a way to automatically implement the workaround with the click of a button. Our Customer Service and Support (CSS) group has a new capability called Fix it that can automatically apply simple solutions to your system. Weve gone ahead and built a Fix it that implements the Disable the parsing of QuickTime content in quartz.dll registry change workaround. We have also built a "Fix it" that will undo the workaround automatically.

     

    To automatically implement the workaround, go to the KB article for the advisory. In the KB article, theres a section titled Fix it for me. Click on the Fix this problem button under "Enable Workaround" in that section. You will then be offered an installer package from the Microsoft website. After youve confirmed that you trust the source of this package, run it on your system. The package will automatically set the appropriate registry keys on your system to implement the workaround. When you want to undo the workaround, click on the "Fix this problem" button under "Disable Workaround" in the same section.

     

    Were also sharing information about this vulnerability and the limited attacks that weve seen with partners in our Microsoft Active Protections Program (MAPP) and our Microsoft Security Response Alliance (MSRA) program to provide information that they can use to provide broader protections to customers.

     

    As always, well continue monitoring the situation and providing more information through the security advisory and the MSRC weblog.

     

    Thanks

    Christopher

  • 00:00 Faking Background Checks for Security Clearances
  • What do you do if you have too many background checks to do, and not enough time to do them? You fake them, of course:

    Eight current and former security clearance investigators say they have been pressured to work faster and take on crushing workloads in recent years, as the government tried to eliminate a backlog that once topped 531,000 cases.

    Investigators have eliminated that backlog, but they now are trying to meet congressionally mandated deadlines to speed up the security clearance process. The 2004 Intelligence Reform and Terrorism Prevention Act requires agencies to issue at least 80 percent of initial security clearances within 120 days after receiving a completed application. This December, agencies must issue at least 90 percent of their initial security clearances within 60 days.

    "This job is a shredder, and agents are grist for the mill," said K.C. Smith, an OPM investigator in Austin, Texas, with 23 years of experience. "There are people who are getting sick, under a lot of stress, their family life is suffering. They are just beat down."

    Investigators say it is common practice to spend nights, weekends and holidays writing up reports, and some don't report the overtime they work for fear it will be held against them in their performance evaluations.

    Some say their superiors have made it clear that the priority is to close cases, and they say they have felt pressure to turn in even incomplete cases that lack crucial interviews or records if it will help them keep their numbers up. A recent Government Accountability Office report found that the Defense Department's security clearance process is plagued by such incomplete cases: 87 percent of the 3,500 initial top-secret security clearance cases Defense approved last year were missing at least one interview or important record.

    It's all a matter of incentives. The investigators were rewarded for completing investigations, not for doing them well.

  • 00:00 Steganography Using TCP Retransmission
  • Research:

    Hiding Information in Retransmissions

    Wojciech Mazurczyk, Milosz Smolarczyk, Krzysztof Szczypiorski

    The paper presents a new steganographic method called RSTEG (Retransmission Steganography), which is intended for a broad class of protocols that utilises retransmission mechanisms. The main innovation of RSTEG is to not acknowledge a successfully received packet in order to intentionally invoke retransmission. The retransmitted packet carries a steganogram instead of user data in the payload field. RSTEG is presented in the broad context of network steganography, and the utilisation of RSTEG for TCP (Transport Control Protocol) retransmission mechanisms is described in detail. Simulation results are also presented with the main aim to measure and compare the steganographic bandwidth of the proposed method for different TCP retransmission mechanisms as well as to determine the influence of RSTEG on the network retransmissions level.

    I don't think these sorts of things have any large-scale applications, but they are clever.
