Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-1000039 in the wild and no public exploit code.\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-2018-1000039/ (Markdown: https://insights.sbomify.com/CVE-2018-1000039/index.md)","id":"CVE-2018-1000039","markdown":"https://insights.sbomify.com/CVE-2018-1000039/index.md","name":"CVE-2018-1000039","record":{"aliases":["DEBIAN-CVE-2018-1000039","GHSA-mv25-m6g9-hcg7","UBUNTU-CVE-2018-1000039"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"MuPDF library","requires_auth":"low_privilege","summary":"Heap use-after-free bugs in MuPDF allow attackers to execute code, read memory, or cause denial of service via crafted PDF files.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mupdf","vendor":"artifex"}],"cvss":{"score":6.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In Artifex MuPDF 1.12.0 and earlier, multiple heap use after free bugs in the PDF parser could allow an attacker to execute arbitrary code, read memory, or cause a denial of service via a crafted 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":"Use after free in n/a","id":"CVE-2018-1000039","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"artifex:mupdf","products":["artifex:mupdf"],"type":"use_after_free","year":"2018"},"n_packages":0,"n_references":13,"next":{"headline":"Memory corruption in n/a","id":"CVE-2018-1000040"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2018-1000038"},"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":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Heap use-after-free bugs in MuPDF allow attackers to execute code, read memory, or cause denial of service via crafted PDF files.","url":"https://insights.sbomify.com/CVE-2018-1000039/"}
