Description Jan Lieskovsky 2012-03-14 13:32:31 UTC

It was found that previously libgdata, a GLib-based library for accessing online service APIs using the GData protocol, did not perform SSL certificates validation even for secured connections. An application, linked against the libgdata library and holding the trust about the other side of the connection being the valid owner of the certificate, could be tricked into accepting of a spoofed SSL certificate by mistake (MITM attack).
