DRAM Rowhammer vulnerability Leads to Kernel Privilege Escalation

Q: DRAM Rowhammer vulnerability Leads to Kernel Privilege Escalation

 
Security researchers have find out ways to hijack the Intel-compatible PCs running Linux by exploiting the physical weaknesses in certain varieties of DDR DRAM (double data rate dynamic random-access memory) chips and gaining higher kernel privileges on the system.
 
The technique, dubbed "rowhammer", was outlined in a blog post published Monday by Google's Project Zero security initiative, a team of top security researchers dedicatedly identifies severe zero-day vulnerabilities in different software.
 
Rowhammer is a problem with recent generation DRAM chips in which repeatedly accessing a row of memory can cause "bit flipping" in an adjacent row which could allow anyone to change the value of contents stored in computer memory.
 
 
WHAT IS ROWHAMMER BUG
DDR memory is arranged in an array of rows and columns, which are assigned to various services, applications and OS resources in large blocks. In order to prevent each application from accessing the memory of other application, they are kept in a "sandbox" protection layer.
 
However, Sandbox protection can be bypassed using Bit flipping technique in which a malicious application needs to repeatedly access adjacent rows of memory in a tiny fraction of a second.
 
As a result, hammering two aggressor memory regions can disturb neighbouring locations, causing charge to leak into or out of neighbouring cells.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Lutomirski had recently reported the CVE-2014-9090 which was caused due to improper handling of faults associated with the Stack Segment (SS) register on the x86 architecture. After notification of CVE-2014-9090, Borislav Petkov pointed out to Lutomirski some further flaws that existed even after vulnerability.  After  research Lutomirski discovered that there were two bugs in the improper handling of Stack Segment (SS) register.  The new kernel kernel vulnerability is now identified CVE-2014-9322 and allows potential hacker to  gain privilege escalation on all X86_64 systems.
 
 
“Any kernel that is not patched against CVE-2014-9090 is vulnerable to privilege escalation due to incorrect handling of a #SS fault caused by an IRET instruction. In particular, if IRET executes on a writeable kernel stack (this was always the case before 3.16 and is sometimes the case on 3.16 and newer), the assembly function general_protection will execute with the user’s gsbase and the kernel’s gsbase swapped,” Lutomirski explained in an advisory.
He added that, “This is likely to be easy to exploit for privilege escalation, except on systems with SMAP or UDEREF. On those systems, assuming that the mitigation works correctly, the impact of this bug may be limited to massive memory corruption and an eventual crash or reboot.”

A vulnerability in the Panda 2016 products that allows the execution of code with elevated permissions has been detected in Small Business Protection and Panda 2016 products. The PSEvents.exe process is periodically run with elevated permissions and has dependencies of libraries located both in the default directory as well as in other system libraries. As the USERS group has Write permissions over the folder where the PSEvent.exe process is run and because the system first looks for libraries run by this process in the execution folder, it may be possible to create a malicious library in the execution folder that will replace one of the libraries installed in other folders. Therefore, a user could run malicious code with SYSTEM privileges.

The Linux kernel 2.6.0 through 2.6.30.4, and 2.4.4 through 2.4.37.4, does not initialize all function pointers for socket operations in proto_ops structures, which allows local users to trigger a NULL pointer dereference and gain privileges by using mmap to map page zero, placing arbitrary code on this page, and then invoking an unavailable operation, as demonstrated by the sendpage operation (sock_sendpage function) on a PF_PPPOX socket.http://web.nvd.nist.gov/view/vuln/detail?v...d=CVE-2009-2692What this amounts to is that someone with physical access to an affected computer could gain root and wreak havoc. Debian and Ubuntu have already released patches and users are urged to update immediately through their distro's update utility.Proof of concept code for an exploit is already available.

Hi,
 
I have been investigating on the privilege escalation vulnerability when we use methods of named pipe. This vulnerability is reported for Windows Server 2000 as per bulletin -
Microsoft Security Bulletin MS00-053 -  Critical and Windows Server 2008 as per bulletin -
Microsoft Security Bulletin MS10-059 - Important.

The similar vulnerability is also reported for Windows Server 2012 in bulletin - Microsoft Security Bulletin MS15-050 - Important. I just want to make sure
that, whether the vulnerability identified for Windows Server 2012 is also due to use of the
CreateNamedPipe method and impersonation or due to some different reason. 
If this vulnerability mentioned in the bulletin - Microsoft
Security Bulletin MS15-050 - Important, is not related to Named Pipe, then is there other vulnerability with Named pipe which leads to privileges escalation?

Latest, and possibly earlier builds, of the PavTPK.sys kernel mode driver of Panda Security software suffers from a heap overflow bug that allows any user to elevate their privileges through an IOCTL request and execute code as SYSTEM by controlling the EIP via a corrupted kernel object.

Upon unsuccessful exploitation the system will crash with a BSoD.
This driver is loaded into kernel memory during boot time and stays resident without touching the disk later.

All Panda Security products using the faulty driver were foujnd to be vulnerable.

Lenovo Security Advisory: LEN-2015-011
Potential Impact: Execution of arbitrary code
Severity: Medium

Summary:
Multiple vulnerabilities have been identified within Lenovo System Update (previously known as ThinkVantage System Update). Lenovo has released a new version of the Lenovo System Update software that addresses these vulnerabilities.

Description:
Lenovo System Update validates all system update files as they are downloaded from the Lenovo servers. However, if the local system contains malware, it is possible that the downloaded updates could be altered before installation creating a race condition. The latest Lenovo System Update release eliminates this possibility. Lenovo System Update uses a service called SUService.exe to run system updates. As part of the authentication and validation process the service only accepts commands if a valid security token is passed along with the command. Vulnerabilities were discovered on how the security tokens were generated allowing an attacker to run commands. The latest Lenovo System Update release fixes the token authentication flaws.
Other security issues were also addressed in this update.
Mitigation Strategy for Customers (what you should do to protect yourself):
Starting from April 1, 2015, run Lenovo System Update and install the latest version of the application, version 5.06.0034 or later. You can determine the currently installed version by opening Lenovo System Update, clicking on the green question mark in the ... Read more

Hi
With this latest vulnerability, i need some clarification about what exactly is a "Non-Compliant Device".
In the KB articles definition, A non-compliant device is one that uses a vulnerable Netlogon secure channel connection.
So that means, lets say you have a Windows machine, that has not been patched correctly, and still uses vulnerable netlogon connection.
So once the DC is patched for this vulnerability, what will happen to this Windows machine?
Will it get denied connection and be reported in event ID: 5827/5828?
Or will it be allowed connection, as it is technically a non-compliant device based on the definition, as it is using vulnerable netlogon connection? And be logged under event ID: 5829?

The other question i have is for the use of the GPO policy: "Domain controller: Allow vulnerable Netlogon secure channel connections"
So i understand that this will bypass the enforcement.
However, if the "Non-Compliant" device is not a windows device, i will assume that the GPO will not work for these devices. So when in enforcement phase, for these such non windows devices that is still using vulnerable netlogon connection, there
is no workaround right? Either get vendor to provide a fix or decommission?

Thanks DM.

Multiplies Escalation by .1% and then halves that Esc figure as only 50% of the .1% will be paid by the client
This result is the annual premium - 8% must be added to the annual premium and then divided by 12 to give the monthly premium

Just another sap who bought the Y50-70 Touch. I'm six months out of warranty, and the left hinge has separated from the lid/locked in place. I can't close the lid for fear of damaging the screen, too, so this isn't much of a laptop any more. Never taken it out of the house, but now it's not an option at all - no way to travel with the thing open all the time.I've flipped through the earlier posts on this. Saw how common it was, and how Lenovo was refusing to cover it under warranty at first. After finally investigating it, they changed their tune... for those under warranty. That implies to me that they know they're at fault for the issue, that they shipped a product to customers later found to be defective.I've been extremely careful with this laptop. It's never left the house and mostly just moves from a side table to my lap <2 feet away. Never dropped or anything. When I first got it, I'd hear this cracking sound sometimes when opening the lid, but I thought it was just from the newness and it'd relax. Would just open it really carefully. With how I use it, the machine made it this long - unfortunately past the warranty ending. It's like being penalized because of my caution.So far, no help from customer support. I've had my case escalated once. The second person I spoke to said it was Lenovo's final decision to not fix my laptop.

RDRAM is faster than DDR-SDRAM but DDR is pretty close and more affordable. If you want to switch, I believe you'd have to change your motherboard as well. That can start to get expensive.

Which DIMM slots should i have the two sticks in? I have them in the 1st and 3rd slots right now. However, unless i manually change it, my computer reads the sticks as DDR-333, when they are actually DDR-400. Any ideas?

Hi all,

I bought a new computer a month ago, and am having BSOD each day. It's a Kernel Security Check Failure, and when i look in the event watcher, i can see a kernel-power critical error.

Thanks for your help !

Please uninstall Gigabyte software, it is known for causing bluescreens and uses a few old drivers.

Please change the system language to english, this helps me understanding the files as I can't understand french.



Diagnostic Test

 DRIVER VERIFIER

   Warning
Please make a backup of your important files and get your rescue media or create one.
Please create a restore point.
Please follow this tutorial to run driver verifier.

Driver verifier stresses your drivers and will crash your pc if any driver fails due to a violation.

Driver verifier should be performed for a max of 48 hours, or when you have a bluescreen, whatever comes first.

If driver verifier has found a violation and you can't get back into windows normally, try to boot into safe mode and reset in safe mode driver verifier, or in the troubleshooting options open command prompt and type verifier /reset.


   Note
Your system will act very sluggishly while driver verifier is enabled, this is normal as your drivers will be being subjected to heavy testing in order to make them crash.

Hi Red here,

I am new to Tech Support Guy, please forgive any mistakes as those of ignorance not arrogance.

I am hoping that someone has already written themselves a spreadsheet that they are willing to share... because I have burnt out out way too many braincells trying to create something that works. I am an advanced Excel user, but this one has me stumped. . I either need help from someone who knows how to perform very complex time calculations in Excel or I need a freeware calculator application I can download fast that will help me out.

I am testing a new call management system that includes automatic escalation to the management should a call not be responded to or resolved within a specified time frame. Escalation is a matter of hours (respond) or days (resolve). The 'resolve by' calculations are very easy, they are working fine. However the 'respond by' time is dependent on the start/end times of the day, whether or not weekends are worked and the timeframe within which the management wants to see escalation happening e.g. "I want to know if no response after X hours (level 1) and again at Y hours (level 2)". The System is capable of accepting this data, varied by department (ours have different hours of operation), and using the data to calculate the day (date) and time on which an alert will be sent to the management following receipt of said inquiry, should no response have been sent to the inquirer.

MY task is to verify the escal... Read more

I've been a frequent flyer here on this board during my short tenure as a former Apple user and returning Lenovo / Thinkpad owner. I need help.  After owning my new Thinkpad Yoga 370 for less than 30 days, the keyboard fell apart and the LCD went bad.  The machine has been in depot repair for three weeks so far, and is predicted to sit on parts hold for another month!  I've called and asked the BOTH the keyboard and the screen be fixed, but it isn't clear that anyone understands that there are TWO problems with the machine. In any case, I want to find out what I need to do to RETURN this machine.  This whole experience has been nothing but awful, I've spent every day I've actually owned the PC and had it in my hands fixing it, re-loading drivers, patching it, tryint to get it to work, and yes, trying to get information in these forums about how to just make the awful thing just do basic tasks like run a Lenovo branded mouse. It's a complete joke. It's unbelieveably ridiculous.  I did my research, you guys are supposed to be the best in the business.  I spent an adequate (like significant) amount of money on a professional grade machine and got something that didn't work right from day one and fell apart. Please PM me so we can exchange contact information.
