<p>libgdata is a GLib-based library for accessing online service APIs using
the GData protocol.
<p>An error in the "_gdata_service_build_session()" function of
gdata-service.c prevents libgdata from properly validating certificates.
<impact type="normal">
<p>A remote attacker could perform man-in-the-middle attacks to spoof
arbitrary SSL servers via a crafted certificate.
<p>There is no known workaround at this time.</p>
<p>All libgdata users should upgrade to the latest version:</p>
