An integer overflow error within the "identify()" function (internal/dcraw_common.cpp) in LibRaw versions prior to 0.18.12 can be exploited to trigger a division by zero via specially crafted NOKIARAW file (Note: This vulnerability is caused due to an incomplete fix of CVE-2018-5804).

• CWE-190Integer Overflow or WraparoundThe 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.
