<p>There is no known workaround at this time.</p>

<p>All ldns users should upgrade to the latest version:</p>
|
|
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-libs/ldns-1.6.11"

<p>Packages which depend on this library may need to be recompiled. Tools
|
|
such as revdep-rebuild may assist in identifying these packages.
