A flaw in PyYAML might allow attackers to execute arbitrary code.
|Package||dev-python/pyyaml on all architectures|
|Affected versions||< 5.1|
|Unaffected versions||>= 5.1|
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"
