python-gnupg - security update

Multiple vulnerabilities were discovered in the Python wrapper for the
Gnu Privacy Guard (GPG). Insufficient sanitising could lead to the
execution of arbitrary shell commands.

For the stable distribution (wheezy), these problems have been fixed in
version 0.3.6-1~deb7u1.

For the testing distribution (jessie), these problems have been fixed in
version 0.3.6-1.

For the unstable distribution (sid), these problems have been fixed in
version 0.3.6-1.

We recommend that you upgrade your python-gnupg packages.
