SSVC AssessmentENISA
Priority Score
Attack Technique
Integer overflow occurs when an arithmetic operation produces a result that exceeds the maximum value a given integer type can store.
Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
