This update addresses the following issue(s):
CVE_2017-7526 is open
CVE_2018-6829 is open
* mainproc.c in GnuPG before 2.2.8 mishandles the original filename during decryption and verification actions, which allows remote attackers to spoof the output that GnuPG sends on file descriptor 2 to other programs that use the "--status-fd 2" option. For example, the OpenPGP data might represent an original filename that contains line feed characters in conjunction with GOODSIG or VALIDSIG status codes. (CVE-2018-12020)

1.4.21-4+deb9u1 (Fri, 08 Jun 2018 22:19:01 +0200)
  * Non-maintainer upload by the Security Team.
  * gpg: Sanitize diagnostic with the original file name (CVE-2018-12020)
* CVE-2018-12020 gnupg2: Improper sanitization of filenames allows for the display of fake status messages and the bypass of signature verification (CVE-2018-12020)
