Mary has discovered that a web application used by her company does not always handle multithreading properly, particularly when multiple threads access the same variable. This could allow an attacker who discovered this vulnerability to exploit it and crash the server. What type of error has Mary discovered?

A race condition can occur when multiple threads in an application are using the same variable and the situation is not properly handled. A buffer overflow is attempting to put more data in a buffer than it is designed to hold. A logic bomb is malware that performs its misdeed when some logical condition is met. As the name suggests, improper error handling is the lack of adequate or appropriate error handling mechanisms within software.
