Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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. (CVE-2026-59203)
