CVE-2020-14343: Improper Input Validation
(updated )
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.
