An integer overflow was addressed with improved input validation. This issue is fixed in Security Update 2022-004 Catalina, macOS Monterey 12.4. An attacker may be able to cause unexpected application termination or arbitrary code execution.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
