    CVE-2018-12020

    Summary: Updated gnupg gnupg2 packages fix a security vulnerability

    Details: Updated gnupg, gnupg2, and python-gnupg packages fix security vulnerability: 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 (CVE-2018-12020).
