<background>
|
|
<p>LibYAML is a YAML 1.1 parser and emitter written in C.</p>
|
|
</background>
|
|
<description>
|
|
<p>The yaml_parser_scan_uri_escapes() function does not properly expand
|
|
strings passed as input, which can result in a heap-based buffer
|
|
overflow.
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>An attacker could provide a specially-crafted YAML document, which, when
|
|
parsed by LibYAML, could result in arbitrary code execution or cause the
|
|
application to crash.
|
|
</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-0.1.6"
|
|
</code>
|
|
|
|
<p>Packages which depend on this library may need to be recompiled. Tools
|
|
such as revdep-rebuild may assist in identifying these packages.
