   An update that fixes one vulnerability is now available.

Description:


   This update for python-PyYAML fixes the following issues:

   - Update to 5.3.1.

   - CVE-2020-14343: A vulnerability was discovered in the PyYAML library,
     where it was 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.
