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...

The vulnerability of the parser for EPS files in the PIL/EpsImagePlugin.py module, a library for working with images using Pillow, allows a hacker to cause a service failure.

The vulnerability of the parser for EPS files in the Pillow image processing library’s EPSImagePlugin.py module lies in the execution of a loop with an unreachable exit condition. Exploiting this vulnerability could allow an attacker to cause service failures when processing specially crafted EPS...
