GHSA-PG7V-JWJ7-P798 Pillow EpsImagePlugin negative %%BeginBinary byte count causes infinite loop denial of service

Summary Pillow's EPS parser PIL/EpsImagePlugin.py accepts a negative byte count in the %%BeginBinary directive. A crafted EPS file can cause Image.open to seek backwards to the same directive and parse it repeatedly, resulting in an infinite loop and CPU denial of service. The issue is triggered...
