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-2012-5340 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-2012-5340/ (Markdown: https://insights.sbomify.com/CVE-2012-5340/index.md)","id":"CVE-2012-5340","markdown":"https://insights.sbomify.com/CVE-2012-5340/index.md","name":"CVE-2012-5340","record":{"aliases":["DEBIAN-CVE-2012-5340","GHSA-g8x3-qg8h-3qqr"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"PDF reader","requires_auth":"none","summary":"Remote attackers can cause a denial of service in SumatraPDF via a corrupt PDF file triggering an integer overflow.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mupdf","vendor":"artifex"},{"product":"sumatrapdf","vendor":"sumatrapdfreader"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"SumatraPDF 2.1.1/MuPDF 1.0 allows remote attackers to cause an Integer Overflow in the lex_number() function via a corrupt PDF file.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2012-12-09","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2012-12-09","kind":"exploitdb","ref":"23246","stars":null,"title":"SumatraPDF 2.1.1/MuPDF 1.0 - Integer Overflow"}],"tier":"weaponised"},"has_fix":true,"headline":"Integer overflow in n/a","id":"CVE-2012-5340","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"artifex:mupdf","products":["artifex:mupdf"],"type":"integer_overflow","year":"2012"},"n_packages":0,"n_references":3,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2012-5341"},"packages":[],"prev":{"headline":"phpMyAdmin multiple cross-site scripting vulnerabilities","id":"CVE-2012-5339"},"products":["n/a"],"published":"2020-01-23","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"}],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-09-13","vendors":["n/a"]},"summary":"Remote attackers can cause a denial of service in SumatraPDF via a corrupt PDF file triggering an integer overflow.","url":"https://insights.sbomify.com/CVE-2012-5340/"}
