We propose SigFree, a realtime, signature-free, out-of-the-box, application layer blocker for preventing buffer overflow attacks, one of the most serious cyber security threats. SigFree can filter out code-injection buffer overflow attack messages targeting at various Internet services such as ...
Improved buffer overflow protection for a computer function call stack is provided by placing a predetermined ShadowKEY value on a function's call stack frame and copying the ShadowKEY, a caller EBP,
A computer system can prevent stack buffer overflow attacks by encrypting return addresses prior to pushing them onto the runtime stack. When an encrypted return address is popped off the runtime stack, the computer system decrypts the encrypted return address to determine the actual return address...
Exploits discussed include: buffer overflows, denial of service, attacks on vulnerable scripts and programs, credential sniffing and spoofing, client parameter manipulation, brute force attacks, web defacements, and more.Barnett introduces the Center for Internet Security Apache Benchmarks, a set of ...
Microsoft Windows Debugger to detect ActiveX execution and buffer overflows Host-based intrusion prevention systems (HIPS) such as Cisco Security Agent See the Additional Information section for links and details about these tools. In addition, the OleView tool can determine if an ActiveX control is...
At a high-level, the SEH overwrite technique uses a software vulnerability to execute arbitrary code by abusing the 32-bit exception dispatching facilities provided by Windows. At a functional level, an SEH overwrite is generally accomplished by using a stack-based buffer overflow to...
Memory buffer problems are the top automotive cybersecurity vulnerability. This means that software can read or write to locations outside of the boundaries of the memory buffer. One example is buffer overflow. This includes: Not checking size of input on copy. Bug allowing writing to arbitrary...
Buffer overflowsIllegal memory accesses are a serious security vulnerability that have been exploited on numerous occasions. In this letter, we present Gandalf, a compiler assisted hardware extension for the OpenRISC processor that thwarts all forms of memory-based attacks. We associate lightweight ...
