pillow: Arbitrary Code Execution via the environment parameter
Pillow through 10.1.0 allows PIL.ImageMath.eval Arbitrary Code Execution via the environment parameter, a different vulnerability than CVE-2022-22817 (which was about the expression parameter).
A vulnerability was found in Pillow, a popular Python imaging library. The flaw identified in the PIL.ImageMath.eval function enables arbitrary code execution by manipulating the environment parameter.
Statement: The vulnerability in Pillow's PIL.ImageMath.eval function poses a significant threat due to its potential for arbitrary code execution. Pillow's widespread use in diverse domains makes this flaw particularly impactful, as it could lead to unauthorized access, data breaches, and compromise of entire systems. The complex exploi
