Synopsis ========
A flaw in PyYAML might allow attackers to execute arbitrary code.
Background ==========
PyYAML is a YAML parser and emitter for Python.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-python/pyyaml < 5.1 >= 5.1
Description ===========
It was found that using yaml.load() API on untrusted input could lead to arbitrary code execution.
Impact ======
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.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All PyYAML users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-python/pyyaml-5.1"
References ==========
