{"id":"USN-3675-1","summary":"gnupg, gnupg2 vulnerabilities","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","modified":"2026-02-10T04:41:21Z","published":"2018-06-11T21:53:17Z","related":["UBUNTU-CVE-2018-12020","UBUNTU-CVE-2018-9234"],"upstream":["CVE-2018-12020","CVE-2018-9234","UBUNTU-CVE-2018-12020","UBUNTU-CVE-2018-9234"],"references":[{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3675-1"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2018-9234"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2018-12020"}],"affected":[{"package":{"name":"gnupg","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/gnupg@1.4.16-1ubuntu2.5?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.4.16-1ubuntu2.5"}]}],"versions":["1.4.14-1ubuntu2","1.4.15-1.1ubuntu1","1.4.15-1.1ubuntu2","1.4.15-2ubuntu1","1.4.16-1ubuntu1","1.4.16-1ubuntu2","1.4.16-1ubuntu2.1","1.4.16-1ubuntu2.3","1.4.16-1ubuntu2.4"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"gnupg","binary_version":"1.4.16-1ubuntu2.5"},{"binary_name":"gnupg-curl","binary_version":"1.4.16-1ubuntu2.5"},{"binary_name":"gpgv","binary_version":"1.4.16-1ubuntu2.5"}]},"database_specific":{"cves_map":{"cves":[{"id":"CVE-2018-12020","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},{"type":"Ubuntu","score":"medium"}]}],"ecosystem":"Ubuntu:14.04:LTS"},"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/usn/USN-3675-1.json"}},{"package":{"name":"gnupg","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/gnupg@1.4.20-1ubuntu3.2?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.4.20-1ubuntu3.2"}]}],"versions":["1.4.18-7ubuntu1","1.4.19-6ubuntu1","1.4.20-1ubuntu1","1.4.20-1ubuntu2","1.4.20-1ubuntu3","1.4.20-1ubuntu3.1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"gnupg","binary_version":"1.4.20-1ubuntu3.2"},{"binary_name":"gnupg-curl","binary_version":"1.4.20-1ubuntu3.2"},{"binary_name":"gpgv","binary_version":"1.4.20-1ubuntu3.2"}]},"database_specific":{"cves_map":{"cves":[{"id":"CVE-2018-12020","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},{"type":"Ubuntu","score":"medium"}]}],"ecosystem":"Ubuntu:16.04:LTS"},"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/usn/USN-3675-1.json"}},{"package":{"name":"gnupg2","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/gnupg2@2.2.4-1ubuntu1.1?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.2.4-1ubuntu1.1"}]}],"versions":["2.1.15-1ubuntu8","2.2.4-1ubuntu1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"dirmngr","binary_version":"2.2.4-1ubuntu1.1"},{"binary_name":"gnupg","binary_version":"2.2.4-1ubuntu1.1"},{"binary_name":"gnupg-agent","binary_version":"2.2.4-1ubuntu1.1"},{"binary_name":"gnupg-l10n","binary_version":"2.2.4-1ubuntu1.1"},{"binary_name":"gnupg-utils","binary_version":"2.2.4-1ubuntu1.1"},{"binary_name":"gnupg2","binary_version":"2.2.4-1ubuntu1.1"},{"binary_name":"gpg","binary_version":"2.2.4-1ubuntu1.1"},{"binary_name":"gpg-agent","binary_version":"2.2.4-1ubuntu1.1"},{"binary_name":"gpg-wks-client","binary_version":"2.2.4-1ubuntu1.1"},{"binary_name":"gpg-wks-server","binary_version":"2.2.4-1ubuntu1.1"},{"binary_name":"gpgconf","binary_version":"2.2.4-1ubuntu1.1"},{"binary_name":"gpgsm","binary_version":"2.2.4-1ubuntu1.1"},{"binary_name":"gpgv","binary_version":"2.2.4-1ubuntu1.1"},{"binary_name":"gpgv-static","binary_version":"2.2.4-1ubuntu1.1"},{"binary_name":"gpgv-win32","binary_version":"2.2.4-1ubuntu1.1"},{"binary_name":"gpgv2","binary_version":"2.2.4-1ubuntu1.1"},{"binary_name":"scdaemon","binary_version":"2.2.4-1ubuntu1.1"}]},"database_specific":{"cves_map":{"cves":[{"id":"CVE-2018-9234","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"Ubuntu","score":"low"}]},{"id":"CVE-2018-12020","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},{"type":"Ubuntu","score":"medium"}]}],"ecosystem":"Ubuntu:18.04:LTS"},"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/usn/USN-3675-1.json"}}],"schema_version":"1.7.3"}
