Note that this fix breaks backward compatibility with Puppet agents older than 3.2.2 and there is no safe way to restore it. This affects puppet agents running on Debian wheezy, we recommend to update to the puppet version shipped in wheezy-backports.

For the stable distribution (jessie), this problem has been fixed in version 3.7.2-4+deb8u1.

For the unstable distribution (sid), this problem has been fixed in version 4.8.2-5.

We recommend that you upgrade your puppet packages.");
