Описание
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.

Отчет
Red Hat Quay 3.2 uses the vulnerable load function, but only to parse the Nginx configuration file, which only contains trusted data.
Меры по смягчению последствий
Use yaml.safe_load or the SafeLoader loader when you parse untrusted input.
