CVE-2026-59203

Pillow EpsImagePlugin negative %%BeginBinary byte count causes infinite loop denial of service PUBLISHED

Description (CNA)

Pillow is a Python imaging library. From 12.0.0 through 12.2.0, Pillow's EPS parser in PIL/EpsImagePlugin.py accepts a negative byte count in the %%BeginBinary directive, allowing a crafted EPS file to cause Image.open() to seek backwards to the same directive and parse it repeatedly in an infinite loop. This issue is fixed in version 12.3.0.
