Overview
Affected versions of this package are vulnerable to Use After Free via ImagingScaleAffine() in src/libImaging/Geometry.c, which deletes a caller-owned output image when its lookup-table allocation fails. When _resize() calls ImagingTransform() and the internal affine transform encounters a memory allocation failure, the output image is freed both inside ImagingScaleAffine() and again by the caller, resulting in a double free that crashes the process. A remote attacker can trigger this condition by supplying an image that causes a memory allocation failure during resize operations, crashing the application.
