Summary
USN-4247-1 fixed several vulnerabilities in python-apt. This update
provides the corresponding updates for Ubuntu 12.04 ESM and Ubuntu 14.04 ESM.
Original advisory details:

Python-apt doesn't check if hashes are signed in `Version.fetch_binary()` and `Version.fetch_source()` of apt/package.py or in `_fetch_archives()` of apt/cache.py in version 1.9.3ubuntu2 and earlier. This allows downloads from unsigned repositories which shou…
