It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-19478 in the wild and no public exploit code.\n\nAffected product: Artifex Ghostscript. 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-2018-19478/ (Markdown: https://insights.sbomify.com/CVE-2018-19478/index.md)","id":"CVE-2018-19478","markdown":"https://insights.sbomify.com/CVE-2018-19478/index.md","name":"CVE-2018-19478","record":{"aliases":["DEBIAN-CVE-2018-19478","GHSA-fcmg-pjrg-hphj","UBUNTU-CVE-2018-19478"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Ghostscript PDF library","requires_auth":"none","summary":"Attackers can cause denial of service by providing a crafted PDF file that triggers excessive computation in Ghostscript.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ghostscript","vendor":"artifex"},{"product":"debian_linux","vendor":"debian"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"In Artifex Ghostscript before 9.26, a carefully crafted PDF file can trigger an extremely long running computation when parsing the file.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Denial of service in n/a","id":"CVE-2018-19478","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"artifex:ghostscript","products":["artifex:ghostscript","debian:debian_linux"],"type":"denial_of_service","year":"2018"},"n_packages":0,"n_references":6,"next":{"headline":"Command injection in n/a","id":"CVE-2018-19486"},"packages":[],"prev":{"headline":"Other in n/a","id":"CVE-2018-19477"},"products":["n/a"],"published":"2019-01-02","related":[{"cvss_score":7.8,"headline":"Artifex Ghostscript Type Confusion","id":"CVE-2017-8291","kev_date_added":"2022-05-24","published":"2017-04-27"},{"cvss_score":9.9,"headline":"Command injection in ghostscript","id":"CVE-2021-3781","kev_date_added":null,"published":"2022-02-16"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-27831","kev_date_added":null,"published":"2025-03-25"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-27832","kev_date_added":null,"published":"2025-03-25"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-27836","kev_date_added":null,"published":"2025-03-25"},{"cvss_score":9.8,"headline":"An issue was discovered in Artifex Ghostscript before 10.05.0.","id":"CVE-2025-27837","kev_date_added":null,"published":"2025-03-25"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2020-36773","kev_date_added":null,"published":"2024-02-04"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Attackers can cause denial of service by providing a crafted PDF file that triggers excessive computation in Ghostscript.","url":"https://insights.sbomify.com/CVE-2018-19478/"}
