For the stable distribution (jessie), this problem has been fixed in version 0.2.5-1+deb8u1 of libtirpc and version 0.2.1-6+deb8u2 of rpcbind.

For the upcoming stable distribution (stretch), this problem has been fixed in version 0.2.5-1.2 and version 0.2.3-0.6 of rpcbind.

For the unstable distribution (sid), this problem has been fixed in version 0.2.5-1.2 and version 0.2.3-0.6 of rpcbind.

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