Description

An integer overflow could occur when OpenEXR processes a crafted file on systems where size_t < 64 bits. This could cause an invalid bytesPerLine and maxBytesPerLine value, which could lead to problems with application stability or lead to other attack paths.

• 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.
