Integer Overflow or Wraparound
There's a flaw in OpenEXR in versions before 2.4.3 and 2.5.x before 2.5.4. A crafted input file that is processed by OpenEXR could cause a shift overflow in the FastHufDecoder, potentially leading to problems with application availability.
CWE-190 - Integer Overflow or Wraparound
The software 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 can introduce other weaknesses when the calculation is used for resource management or execution control.
