Conda update fails with SSL error CERTIFICATE_VERIFY_FAILED

I have a problem with conda update. Specifically, I tried doing

conda update <package>

, and I got the following error:

Could not connect to https://repo.continuum.io/pkgs/free/osx-64/decorator-4.0.2-py27_0.tar.   bz2 Error: Connection error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590): https://repo.continuum.io/pkgs/free/osx-64/decorator-4.0.2-py27_0.tar.bz2

The full output of the command was the following:
