Which statement describes a buffer overflow attack?

• Application vulnerabilities are exploited to execute commands with the privileges of the user on the target device.
• Data is written beyond the limits of the memory area allocated to an application.
• Data on a XML database is corrupted and threatens the security of a website.
• Malicious scripts on a web page are unknowingly passed to the browser of the victim.

Explanation: A buffer overflow attack causes data to be written beyond the limits of the memory area allocated to an application. An XML injection attack can corrupt the data on the XML database and threaten the security of the website. Cross-site scripting occurs when the victim accesses a web page and malicious scripts are unknowingly passed to their browser. Remote code execution allows a cybercriminal to take advantage of application vulnerabilities to execute any command with the privileges of the user running the application on the target device.
