Overview
Affected versions of this package are vulnerable to NULL Pointer Dereference via ImagingExpand in src/libImaging/Filter.c when processing a zero-dimension image through RankFilter or related filters. An attacker can supply an image with a width or height of zero, triggering undefined behavior or a crash in the C-level filter pipeline due to the absence of a zero-dimension guard before memory allocation and pixel processing.
