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-2018-6544 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-2018-6544/ (Markdown: https://insights.sbomify.com/CVE-2018-6544/index.md)","id":"CVE-2018-6544","markdown":"https://insights.sbomify.com/CVE-2018-6544/index.md","name":"CVE-2018-6544","record":{"aliases":["ALPINE-CVE-2018-6544","DEBIAN-CVE-2018-6544","GHSA-3vq6-g92c-jm9j","UBUNTU-CVE-2018-6544"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"MuPDF library","requires_auth":"none","summary":"Remote attackers can cause a denial of service in MuPDF via a crafted PDF document triggering recursive object stream references.","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:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-674","name":"Uncontrolled Recursion"}],"description":"pdf_load_obj_stm in pdf/pdf-xref.c in Artifex MuPDF 1.12.0 could reference the object stream recursively and therefore run out of error stack, which allows remote attackers to cause a denial of service via a crafted PDF document.","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-2018-6544","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":6,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2018-6545"},"packages":[],"prev":{"headline":"Integer overflow in n/a","id":"CVE-2018-6543"},"products":["n/a"],"published":"2018-02-02","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Remote attackers can cause a denial of service in MuPDF via a crafted PDF document triggering recursive object stream references.","url":"https://insights.sbomify.com/CVE-2018-6544/"}
