PyYAML is a YAML parser and emitter for Python.
A vulnerability has been discovered in PyYAML. Please review the CVE identifier referenced below for details.
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.
There is no known workaround at this time.
All PyYAML users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-python/pyyaml-5.4"
A flaw in PyYAML might allow attackers to execute arbitrary code.

PyYAML is a YAML parser and emitter for Python.
It was found that using yaml.load() API on untrusted input could lead to arbitrary code execution.
A remote attacker could entice a user to process specially crafted input in an application using yaml.load() from PyYAML, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.
There is no known workaround at this time.
All PyYAML users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-python/pyyaml-5.1"
