arbitrary code execution.

<impact type="high">
|
|
<p>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.

</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All PyYAML users should upgrade to the latest version:</p>
|
|
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-python/pyyaml-5.1"
|
|
</code>
