LoginPossible integer overflow on 32-bit systems when reading GIF images
libvips is a fast image processing library with low memory needs. On 32-bit systems in versions before and including 8.18.0, the `gifload` operation could incorrectly determine dimensions leading to an integer overflow. This has been patched in version 8.18.1.

CWE-190 Integer Overflow or Wraparound
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.
