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.
This variant makes use of port contention in shared resources and can be applied even in single-threaded cores. [ 53 ] In late April 2021, a related vulnerability was discovered that breaks through the security systems designed to mitigate Spectre through use of the micro-op cache.
A penetration test, colloquially known as a pentest, is an authorized simulated cyberattack on a computer system, performed to evaluate the security of the system; [1] this is not to be confused with a vulnerability assessment. [2]
In July 2023 a critical vulnerability in the Zen 2 AMD microarchitecture called Zenbleed was made public. [59] AMD released a microcode update to fix it. [60] In August 2023 a vulnerability in AMD's Zen 1, Zen 2, Zen 3, and Zen 4 microarchitectures called Inception [61] [62] was revealed and assigned CVE-2023-20569. According to AMD it is not ...
A vulnerability assessment is the process of identifying, quantifying, and prioritizing (or ranking) the vulnerabilities in a system. Examples of systems for which vulnerability assessments are performed include, but are not limited to, information technology systems, energy supply systems, water supply systems, transportation systems, and communication systems.
Metasploit was created by H. D. Moore in 2003 as a portable network tool using Perl.By 2007, the Metasploit Framework had been completely rewritten in Ruby.On October 21, 2009, the Metasploit Project announced [4] that it had been acquired by Rapid7, a security company that provides unified vulnerability management solutions.
[2] [13] Around July 16, 2003: White hat hackers create proof-of-concept code verifying that the unpatched systems are vulnerable. The code was not released. [5] July 17, 2003: CERT/CC releases a warning and suggests blocking port 135. [14] July 21, 2003: CERT/CC suggests also blocking ports 139 and 445. [14]
The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. [3] They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the ...
