It supports games for the Super Nintendo Entertainment System, Nintendo Entertainment System, Nintendo 64, Nintendo DS, Game Boy, Game Boy Color, Game Boy Advance, and Sega Genesis. Development of Delta started prior to Testut entering university, with it being a ...
Exploit (computer security) An exploit (from the English verb to exploit, meaning "to use something to one’s own advantage") is a piece of software, a chunk of data, or a sequence of commands that takes advantage of a bug or vulnerability to cause unintended or unanticipated behavior to occur on computer software, hardware, or something ...
Log4Shell ( CVE-2021-44228) is a zero-day vulnerability in Log4j, a popular Java logging framework, involving arbitrary code execution. [2] [3] The vulnerability had existed unnoticed since 2013 and was privately disclosed to the Apache Software Foundation, of which Log4j is a project, by Chen Zhaojun of Alibaba Cloud 's security team on 24 ...
Zero-day vulnerability. A zero-day (also known as a 0-day) is a vulnerability or security hole in a computer system unknown to its owners, developers or anyone capable of mitigating it. [1] Until the vulnerability is remedied, threat actors can exploit it in a zero-day exploit, or zero-day attack. [2]
In computer security, arbitrary code execution (ACE) is an attacker's ability to run any commands or code of the attacker's choice on a target machine or in a target process. [1] An arbitrary code execution vulnerability is a security flaw in software or hardware allowing arbitrary code execution. A program that is designed to exploit such a ...
Heartbeat (computing) In computer science, a heartbeat is a periodic signal generated by hardware or software to indicate normal operation or to synchronize other parts of a computer system. [1] [2] Heartbeat mechanism is one of the common techniques in mission critical systems for providing high availability and fault tolerance of network ...
Fuzzing. In programming and software development, fuzzing or fuzz testing is an automated software testing technique that involves providing invalid, unexpected, or random data as inputs to a computer program. The program is then monitored for exceptions such as crashes, failing built-in code assertions, or potential memory leaks.
Meltdown exploit. Ordinarily, the mechanisms described above are considered secure. They provide the basis for most modern operating systems and processors. Meltdown exploits the way these features interact to bypass the CPU's fundamental privilege controls and access privileged and sensitive data from the operating system and other processes.
