An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-12020 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2018-12020/ (Markdown: https://insights.sbomify.com/CVE-2018-12020/index.md)","id":"CVE-2018-12020","markdown":"https://insights.sbomify.com/CVE-2018-12020/index.md","name":"CVE-2018-12020","record":{"aliases":["ALPINE-CVE-2018-12020","CLEANSTART-2026-SJ88469","DEBIAN-CVE-2018-12020","DSA-4222-1","DSA-4223-1","DSA-4224-1","GHSA-678p-6r6j-65f9","MGASA-2018-0292","RHSA-2018:2180","RHSA-2018:2181","SUSE-SU-2018:1696-1","SUSE-SU-2018:1698-1","SUSE-SU-2018:1698-2","SUSE-SU-2018:1814-1","UBUNTU-CVE-2018-12020","USN-3675-2"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"GnuPG encryption library","requires_auth":"none","summary":"Attackers can spoof GnuPG status output via crafted filenames when using status-fd, potentially bypassing signature verification checks.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"gnupg","vendor":"gnupg"},{"product":"enterprise_linux_desktop","vendor":"redhat"},{"product":"enterprise_linux_server","vendor":"redhat"},{"product":"enterprise_linux_server_aus","vendor":"redhat"},{"product":"enterprise_linux_server_eus","vendor":"redhat"},{"product":"enterprise_linux_server_tus","vendor":"redhat"},{"product":"enterprise_linux_workstation","vendor":"redhat"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-706","name":"Use of Incorrectly-Resolved Name or Reference"}],"description":"mainproc.c in GnuPG before 2.2.8 mishandles the original filename during decryption and verification actions, which allows remote attackers to spoof the output that GnuPG sends on file descriptor 2 to other programs that use the \"--status-fd 2\" option.
