Debian Security Advisory 1719-2 - Changes in DSA-1719-1 caused GNUTLS to reject X.509v1 certificates as CA root certificates by default, as originally described in the documentation. However, it turned out that there is still significant use of historic X.509v1 CA root certificates, so this constitutes an unacceptable regression. This update reverses this part of the changes in DSA-1719-1. Note that the X.509v1 certificate format does not distinguish between server and CA certificates, which means that an X.509v1 server certificates is implicitly converted into a CA certificate when added to the trust store (which was the reason for the change in DSA-1719-1).
