9.0.0- Upgrade pillow to this version or later
Description
Pillow is the friendly PIL (Python Imaging Library) fork. path_getbbox in path.c in Pillow before 9.0.0 improperly initializes ImagePath.Path.
Affected versions

| Package | Vulnerable | Fixed in |
|---|---|---|
| pillow | < 9.0.0 |
9.0.0 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
pillow PyPI → 9.0.0
- pip
pip install --upgrade "pillow>=9.0.0"- poetry
poetry add "pillow>=9.0.0"- uv
uv add "pillow>=9.0.0"

Weakness
CWE-665: Improper Initialization
The product does not initialize or incorrectly initializes a resource, which might leave the resource in an unexpected state when it is accessed or used.
How to prevent it
- Requirements: Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, in Java, if the programmer does not explicitly initialize a variable, then the code could produce a compile-time error (if the variable is local) or automatically initialize the variable to the default value for the variable's type. In Perl, if explicit initialization is not performed, then a default value of undef is assigned, which is interpreted as 0, false, or an equivalent value depending on the context in which the variable is accessed.
- Architecture and Design: Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
- Implementation: Explicitly initialize all your variables and other data stores, either during declaration or just before the first usage.
- Implementation: Pay close attention to complex conditionals that affect initialization, since some conditions might not perform the initialization.
- Implementation: Avoid race conditions (CWE-362) during initialization routines.
- Build and Compilation: Run or compile your product with settings that generate warnings about uninitialized variables or data.
