Vulnerable:

Security database references:

In Mitre's CVE dictionary: CVE-2018-12020.

More information:

Marcus Brinkmann discovered that GnuPG 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 oldstable distribution (jessie), this problem has been fixed in version 1.4.18-7+deb8u5.

We recommend that you upgrade your gnupg packages.
