| pyyaml | ≥ 5.1, < 5.2≥ 5.1, < 5.2b1 | 5.25.2b1 |
| pyyaml | ≥ 5.1, ≤ 5.1.2 |
PyYAML 5.1 through 5.1.2 has insufficient restrictions on the load and load_all functions because of a class deserialization issue, e.g., Popen is a class in the subprocess module. NOTE: this issue exists because of an incomplete fix for CVE-2017-18342.
