    Summary: gnupg2 vulnerability

    Details: USN-3675-1 fixed a vulnerability in GnuPG 2 for Ubuntu 18.04 LTS and Ubuntu 17.10. This update provides the corresponding update for GnuPG 2 in Ubuntu 16.04 LTS and Ubuntu 14.04 LTS. Original advisory details: Marcus Brinkmann discovered that during decryption or verification, GnuPG did not properly filter out terminal sequences when reporting the original filename. An attacker could use this to specially craft a file that would cause an application parsing GnuPG output to incorrectly interpret the status of the cryptographic operation reported by GnuPG.
