DescriptionNVD

Passing nested lists as coordinates to APIs that accept coordinates such as ImagePath.Path, ImageDraw.ImageDraw.polygon and ImageDraw.ImageDraw.line could cause a heap buffer overflow, as nested lists were recursively unpacked beyond the allocated buffer. Coordinate lists are now validated to contain exactly two numeric coordinates. This was introduced in Pillow 11.2.1.

AnalysisAI

Heap buffer overflow in Pillow 11.2.1 through 12.1.x allows local attackers to cause denial of service or potentially execute arbitrary code by passing deeply nested list structures as coordinates to ImagePath.Path, ImageDraw.polygon, or ImageDraw.line APIs, which recursively unpack coordinates beyond allocated buffer boundaries.
