Ubuntu Security Notice USN-3675-2
June 15, 2018

gnupg2 vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

GnuPG 2 could be made to present validity information incorrectly.

Software Description:
- gnupg2: GNU privacy guard - a free PGP replacement

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.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 16.04 LTS:
gnupg2 2.1.11-6ubuntu2.1

Ubuntu 14.04 LTS:
gnupg2 2.0.22-3ubuntu1.4

In general, a standard system update will make all the necessary changes.
