Techniques & Countermeasures

  • CWE-94•Improper Control of Generation of Code ('Code Injection')

    The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.

  • CWE-95•Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection')

    The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes code syntax before using the input in a dynamic evaluation call (e.g. "eval").

Affected Systems

  • debian•debian_linux

    10.0

  • PyPI•pillow

    < 10.2.0

  • python•pillow

    ≤ 10.1.0
