<p>LibYAML is a YAML 1.1 parser and emitter written in C.</p>

<description>
|
|
<p>A heap-based buffer overflow flaw was found in the way libyaml parsed
|
|
YAML tags.
|

</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>A remote attacker could provide a specially-crafted YAML document which
|
|
when parsed by LibYAML, would cause the application to crash or,
|
|
potentially, execute arbitrary code with the privileges the user who is
|
|
running the application.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All LibYAML users should upgrade to the latest version:</p>
|
|
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-libs/libyaml-0.1.5"
|
|
</code>
