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: It is not confirmed as exploited in the wild, but public exploit code for CVE-2018-1000036 exists.\n\nAffected product: Artifex Mupdf. 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-2018-1000036/ (Markdown: https://insights.sbomify.com/CVE-2018-1000036/index.md)","id":"CVE-2018-1000036","markdown":"https://insights.sbomify.com/CVE-2018-1000036/index.md","name":"CVE-2018-1000036","record":{"aliases":["DEBIAN-CVE-2018-1000036","GHSA-cqwp-8vf4-jg4p","UBUNTU-CVE-2018-1000036"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"PDF parsing library","requires_auth":"none","summary":"An attacker can cause a denial of service via memory leaks in the PDF parser by providing a crafted file to applications using this library.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mupdf","vendor":"artifex"},{"product":"debian_linux","vendor":"debian"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-772","name":"Missing Release of Resource after Effective Lifetime"}],"description":"In Artifex MuPDF 1.12.0 and earlier, multiple memory leaks in the PDF parser allow an attacker to cause a denial of service (memory leak) via a crafted file.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Denial of service in n/a","id":"CVE-2018-1000036","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"artifex:mupdf","products":["artifex:mupdf","debian:debian_linux"],"type":"denial_of_service","year":"2018"},"n_packages":0,"n_references":5,"next":{"headline":"Denial of service in n/a","id":"CVE-2018-1000037"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2018-1000035"},"products":["n/a"],"published":"2018-05-24","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-7321","kev_date_added":null,"published":"2019-06-13"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2016-6525","kev_date_added":null,"published":"2016-09-22"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2011-0341","kev_date_added":null,"published":"2011-05-13"},{"cvss_score":8.6,"headline":"Memory corruption in MuPDF","id":"CVE-2016-8728","kev_date_added":null,"published":"2018-04-24"},{"cvss_score":7.8,"headline":"Use after free in mupdf","id":"CVE-2021-3407","kev_date_added":null,"published":"2021-02-23"},{"cvss_score":7.8,"headline":"Use after free in n/a","id":"CVE-2020-16600","kev_date_added":null,"published":"2020-12-09"},{"cvss_score":7.8,"headline":"Integer overflow in n/a","id":"CVE-2012-5340","kev_date_added":null,"published":"2020-01-23"}],"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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-09-13","vendors":["n/a"]},"summary":"An attacker can cause a denial of service via memory leaks in the PDF parser by providing a crafted file to applications using this library.","url":"https://insights.sbomify.com/CVE-2018-1000036/"}
