Details
USN-3675-1 fixed a vulnerability in GnuPG. This update provides

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.
