Availability: DoS: Crash, Exit, or Restart

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 session.

Potential Mitigations

Make sensitive open/close operation non reachable by directly user-controlled data (e.g. open/close resources)

Phase: Implementation

Description: 

Perform input validation on user data.
