Vulnerability
Flaw in software which lets attackers in
A vulnerability is a flaw in an application or piece of software which allows a malicious person to carry out unauthorised actions. These actions can range from escalating privileges to executing malicious code on the target system. Most vulnerabilities are the result of errors in programming, such as failing to properly check the behaviour of code when faced with unexpected or unusual circumstances.
A common form of vulnerability is the buffer overflow.
