CVE-2020-14343

Se detectó una vulnerabilidad en la biblioteca PyYAML en versiones anteriores a 5.4, donde es susceptible una ejecución de código arbitrario cuando se procesan archivos YAML no confiables por medio del método full_load o con el cargador FullLoader. Unas aplicaciones que usan la biblioteca para procesar entradas que no son confiables pueden ser vulnerables a este fallo. Este fallo le permite a un atacante ejecutar código arbitrario en el sistema abusando del constructor python/object/new. Este fallo se debe a una corrección incompleta para CVE-2020-1747

A vulnerability was discovered in the PyYAML library, 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.
