For example, in 2008, a vulnerability (CVE-2008-0923) in VMware discovered by Core Security Technologies made VM escape possible on VMware Workstation 6.0.2 and 5.5.4. [ 3 ] [ 4 ] A fully working exploit labeled Cloudburst was developed by Immunity Inc. for Immunity CANVAS (a commercial penetration testing tool). [ 5 ]
Address space layout randomization (ASLR) is a computer security technique involved in preventing exploitation of memory corruption vulnerabilities. [1] In order to prevent an attacker from reliably redirecting code execution to, for example, a particular exploited function in memory, ASLR randomly arranges the address space positions of key data areas of a process, including the base of the ...
Speculative execution exploit Variant 4, [8] is referred to as Speculative Store Bypass (SSB), [1] [9] and has been assigned CVE-2018-3639. [7] SSB is named Variant 4, but it is the fifth variant in the Spectre-Meltdown class of vulnerabilities. [7] Steps involved in exploit: [1] "Slowly" store a value at a memory location
OpenVMS, often referred to as just VMS, [8] is a multi-user, multiprocessing and virtual memory-based operating system.It is designed to support time-sharing, batch processing, transaction processing and workstation applications. [9]
Almost all published evasion techniques modify network attacks. The 1998 paper Insertion, Evasion, and Denial of Service: Eluding Network Intrusion Detection popularized IDS evasion, and discussed both evasion techniques and areas where the correct interpretation was ambiguous depending on the targeted computer system. The 'fragroute' and ...
The security systems are rendered ineffective against well-designed evasion techniques, in the same way a stealth fighter can attack without detection by radar and other defensive systems. A good analogy to evasions is a system designed to recognize keywords in speech patterns on a phone system, such as “break into system X”.
Since the Linux kernel cannot sustain the 10G packet rate [citation needed], then some bypass technologies for a fast path are used. The main bypass technologies are either based on a limited set of features such as Open vSwitch (OVS) with its DPDK user space implementation or based on a full feature and offload of Linux processing such as ...
In computing, remote direct memory access (RDMA) is a direct memory access from the memory of one computer into that of another without involving either one's operating system.
