  "details": "Marcus Brinkmann discovered that during decryption or verification,\nGnuPG did not properly filter out terminal sequences when reporting the\noriginal filename. An attacker could use this to specially craft a file\nthat would cause an application parsing GnuPG output to incorrectly\ninterpret the status of the cryptographic operation reported by GnuPG.\n(CVE-2018-12020)\n\nLance Vick discovered that GnuPG did not enforce configurations where\nkey certification required an offline primary Certify key. An attacker\nwith access to a signing subkey could generate certifications that\nappeared to be valid. This issue only affected Ubuntu 18.04 LTS.\n(CVE-2018-9234)\n",
