Integrated GPUs may allow side-channel and rowhammer attacks using WebGL ("Glitch")

Overview Some platforms with integrated GPUs, such as smartphones, may allow both side-channel and rowhammer attacks via WebGL, which may allow a remote attacker to compromise the browser on an affected platform. An attack technique that leverages these vulnerabilities is called "GLitch."...

Intel In Security Hot Seat Over Reported CPU Design Flaw

UPDATE Intel is grappling with what many experts are describing as a processor design flaw impacting CPUs used in Linux, Windows and some macOS systems. The reported flaw is tied to Intel’s kernel virtual memory system that could allow an attacker to access kernel-protected data such as passwords...

Rowhammer Attacks Come to MLC NAND Flash Memory

The Rowhammer attacks developed by Google more than two years ago put the focus on hardware front and center. That research allowed attackers to flip dynamic random access memory DRAM bits in order to induce those memory cells to change their state. Google’s research enabled kernel-level privileg...

The ASLR protection mechanism is a breakthrough attack technical analysis-vulnerability warning-the black bar safety net

Recently, hardware-based attacks have been started by Rowhammer memory leaks or bypass the address space layout randomization protection mechanisms to attack the system, these attacks are based on the processor's memory management unit MMU with a page table interactive interactive manner. These...

Google Releases Supplemental Patch for Dirty Cow Vulnerability

Google’s November Android Security Bulletin, released Monday, patched 15 critical vulnerabilities and addressed 85 CVEs overall. But conspicuously absent is a fix for the Linux race condition vulnerability known as Dirty Cow Copy-on-Write that also impacts Android. While Google didn’t issue an...

How to use Rowhammer vulnerability Root Android phone with Video demo+Exploit source code-the vulnerabilities and early warning-the black bar safety net

! Recently, security research experts through research found a root the Android phone to the new method, i.e., by Rowhammer vulnerability to root Android phone. In addition, the attacker can even use this exploit with presently known Android vulnerabilities Bandroid and Stagefright to the target...

Android Rowhammer attack vulnerability (Drammer)

Project Description Drammer is a new attack that exploits the Rowhammer hardware vulnerability on Android devices. It allows attackers to take control over your mobile device by hiding it in a malicious app that requires no permissions. Practically all devices are possibly vulnerable and must wai...

Critical Android Vulnerability 'Drammer' Impacts Millions of Handsets

Researchers have published details of a new method for exploiting a problem with Android devices tied to a hardware flaw within DRAM memory modules that can allow attackers to get root-level access to target machines. The vulnerability, dubbed Drammer, could give an attacker root access to millio...

New Drammer Android Hack lets Apps take Full control (root) of your Phone

Earlier last year, security researchers from Google's Project Zero outlined a way to hijack the computers running Linux by abusing a design flaw in the memory and gaining higher kernel privileges on the system. Now, the same previously found designing weakness has been exploited to gain unfettere...

Keep an eye on your computer: memory vulnerable to malicious attacks-vulnerability warning-the black bar safety net

Recently, security researchers demonstrated a new Rowhammer attack, using this technology can attack some of the DDR4 memory module. Rowhammer attacks affect a wide Rowhammer attack is known to be in the 2 0 1 4 year, Carnegie Mellon University researchers in a sufficient number of access number ...

This year“white hat”are dug up? Breakdown 2 0 1 5 in those affected world of vulnerabilities-vulnerability warning-the black bar safety net

About the past 2 0 1 5 years network security on thin ice year: the countless fatal vulnerability is discovered, be repaired or be caring people use...fortunately, in the global white hat hacker's efforts, many fatal vulnerabilities are to catch the bad guys discover before it has been...

Google Chrome memory corruption vulnerability (CNVD-2015-02654)

Google Chrome is a web browser developed by the American company Google Google. Google Chrome versions prior to 42.0.2311.90, the function NaClSandbox::InitializeLayerTwoSandbox within components/nacl/loader/sandboxlinux/naclsandboxlinux.cc Failure to apply RLIMITAS and RLIMITDATA restrictions to...

DRAM chip kernel mention the right vulnerability analysis-vulnerability warning-the black bar safety net

Security researchers found in the Intel PC on Linux systems you can use certain types of DDR DRAM chips in the presence of physical defects to obtain the highest system privileges. This technique is known as“Rowhammer”, which may make the recent generation of DRAM chips times the memory access...

DRAM 'Rowhammer' Memory Bit Flip Privilege Elevation Vulnerability

DRAM, or Dynamic Random Access Memory, is the most common type of system memory. DRAM devices have security vulnerabilities that allow a local user to run a program that continuously accesses the DRAM, flipping the value of a cell from 1 to 0, or vice versa, allowing elevated privileges to execut...

Rowhammer Hardware Exploit Poses Threat DRAM Memory in Many Laptops, PCs

Software, from web apps, to operating systems to firmware, has been abused and exploited every which way from Sunday for decades by both researchers and attackers. Now, it is hardware’s turn in the spotlight, as researchers have published details of a new method for exploiting a problem with some...

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"...
