CVE-2020-1747 @ Python-PyYAML-3.12

[pedrompflopes]

Vulnerable Package issue exists @ Python-PyYAML-3.12 in branch main

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.
