Short explanation

Pillow is vulnerable to argument injection and potential remote command execution when invoking Ghostscript for EPS input [S0].

Why does it matter?

This flaw allows attackers to inject Ghostscript arguments and potentially execute arbitrary commands, posing significant risks [S0].

What should be done?

  • Follow the vendor advisory [S0].
  • Update the vulnerable library [S0].

Show the technical text from the sources

Pillow is a Python imaging library. From 2.6.0 until 13.0.0, Pillow is vulnerable to argument injection when invoking Ghostscript for EPS input. EpsImagePlugin.Ghostscript passes a caller-controlled input filename after -f without converting it to a safe absolute path, so a name beginning with a hyphen can be interpreted as a Ghostscript option. An attacker who controls the filename can inject Ghostscript arguments. Arbitrary command execution specifically requires a leading @ argument-file filename and control of the referenced text file containing additional Ghostscript arguments; the reported chain reproduces with the default -dSAFER invocation. This issue is fixed in version 13.0.0.
