The product contains an assert() or similar statement that can be triggered by an attacker, which leads to an application exit or other behavior that is more severe than necessary.
While assertion is good for catching logic errors and reducing the chances of reaching more serious vulnerability conditions, it can still lead to a denial of service.
For example, if a server handles multiple simultaneous connections, and an assert() occurs in one single connection that causes all other connections to be dropped, this is a reachable assertion that leads to a denial of service.

Technical Impact: DoS: crash / exit /
An attacker that can trigger an assert statement can still lead to a
denial of service if the relevant code can be triggered by an attacker,
and if the scope of the assert() extends beyond the attacker's own
In the excerpt below, an AssertionError (an unchecked exception) is
thrown if the user hasn't entered an email address in an HTML
