BoundWarden is a new spatial memory enforcement approach that utilizes a combination of compile-time transformation and runtime concurrent monitoring techniques. [23] Fuzz testing is well-suited for finding memory safety bugs and is often used in combination with dynamic checkers such as AddressSanitizer.
In computer security, a cold boot attack (or to a lesser extent, a platform reset attack) is a type of side channel attack in which an attacker with physical access to a computer performs a memory dump of a computer's random-access memory (RAM) by performing a hard reset of the target machine.
Meltdown exploits a race condition, inherent in the design of many modern CPUs.This occurs between memory access and privilege checking during instruction processing. . Additionally, combined with a cache side-channel attack, this vulnerability allows a process to bypass the normal privilege checks that isolate the exploit process from accessing data belonging to the operating system and other ...
The Linux kernel supports the NX bit on x86-64 and IA-32 processors that support it, such as modern 64-bit processors made by AMD, Intel, Transmeta and VIA. The support for this feature in the 64-bit mode on x86-64 CPUs was added in 2004 by Andi Kleen, and later the same year, Ingo Molnár added support for it in 32-bit mode on 64-bit CPUs.
Rowhammer (also written as row hammer or RowHammer) is a computer security exploit that takes advantage of an unintended and undesirable side effect in dynamic random-access memory (DRAM) in which memory cells interact electrically between themselves by leaking their charges, possibly changing the contents of nearby memory rows that were not addressed in the original memory access.
Memory safety. In memory-unsafe programming languages, lower-level issues such as buffer overflows and race conditions can be exploited to take partial or complete control of the software. Spoofing and friends. Often targeting web domain names with attacks such as phishing, spoofing, and typosquatting. GUI attacks.
On March 5, 2020, computer security experts reported another Intel chip security flaw, besides the Meltdown and Spectre flaws, with the systematic name CVE-2019-0090 (or "Intel CSME Bug"). [16] This newly found flaw is not fixable with a firmware update, and affects nearly "all Intel chips released in the past five years".
An attacker could, for example, use a social engineering attack and send a "lucky winner" a rogue Thunderbolt device. Upon connecting to a computer, the device, through its direct and unimpeded access to the physical address space, would be able to bypass almost all security measures of the OS and have the ability to read encryption keys, install malware, or control other system devices.
