Common Vulnerabilities and Exposures (CVE) is a dictionary of common names (i.e., CVE Identifiers) for publicly known information security vulnerabilities. CVE's common identifiers make it easier to share data across separate network security databases and tools, and provide a baseline for evaluating the coverage of an organization's security ...
A security bug or security defect is a software bug that can be exploited to gain unauthorized access or privileges on a computer system. Security bugs introduce security vulnerabilities by compromising one or more of: Authentication of users and other entities [1] Authorization of access rights and privileges [1] Data confidentiality; Data ...
Software vulnerability scanners are typically unable to detect zero-day vulnerabilities, but are more effective at finding known vulnerabilities based on a database. These systems can find some known vulnerabilities and advise fixes, such as a patch.
Code injection is a computer security exploit where a program fails to correctly process external data, such as user input, causing it to interpret the data as executable commands. An attacker using this method "injects" code into the program while it is running.
In computer security, a threat is a potential negative action or event enabled by a vulnerability that results in an unwanted impact to a computer system or application.. A threat can be either a negative "intentional" event (i.e. hacking: an individual cracker or a criminal organization) or an "accidental" negative event (e.g. the possibility of a computer malfunctioning, or the possibility ...
In 2020, a team at Google similarly reported that 70% of all "severe security bugs" in Chromium were caused by memory safety problems. Many other high-profile vulnerabilities and exploits in critical software have ultimately stemmed from a lack of memory safety, including Heartbleed [8] and a long-standing privilege escalation bug in sudo.

Fuzzing is used mostly as an automated technique to expose vulnerabilities in security-critical programs that might be exploited with malicious intent. [ 6 ] [ 16 ] [ 17 ] More generally, fuzzing is used to demonstrate the presence of bugs rather than their absence.
