CVE ID         : CVE-2018-12020
Debian Bug     : 901088

Marcus Brinkmann discovered that GnuGPG performed insufficient
sanitisation of file names displayed in status messages, which could be
abused to fake the verification status of a signed email.

Details can be found in the upstream advisory at
https://lists.gnupg.org/pipermail/gnupg-announce/2018q2/000425.html

For the stable distribution (stretch), this problem has been fixed in
version 1.4.21-4+deb9u1.

We recommend that you upgrade your gnupg1 packages.

For the detailed security status of gnupg1 please refer to its security
tracker page at:
