CVE-2020-1747 ### Vulnerable Library - PyYAML-3.12.tar.gz

YAML parser and emitter for Python

Library home page: https://files.pythonhosted.org/packages/4a/85/db5a2df477072b2902b0eb892feb37d88ac635d36245a72a6a69b23b383a/PyYAML-3.12.tar.gz

Path to dependency file: /components/aws/sagemaker/requirements.txt

Path to vulnerable library: /components/aws/sagemaker/requirements.txt

Dependency Hierarchy: - :x: **PyYAML-3.12.tar.gz** (Vulnerable Library)

Found in base branch: master

### Vulnerability Details

A vulnerability was discovered in the PyYAML library in versions before 5.3.1, where it is susceptible to arbitrary code execution when it processes untrusted YAML files through the full_load method or with the FullLoader loader. Applications that use the library to process untrusted input may be vulnerable to this flaw. An attacker could use this flaw to execute arbitrary code on the system by abusing the python/object/new constructor.

### Vulnerability Details

A vulnerability was discovered in the PyYAML library in versions before 5.4, where it is susceptible to arbitrary code execution when it processes untrusted YAML files through the full_load method or with the FullLoader loader. Applications that use the library to process untrusted input may be vulnerable to this flaw. This flaw allows an attacker to execute arbitrary code on the system by abusing the python/object/new constructor. This flaw is due to an incomplete fix for CVE-2020-1747.
