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-2018-1000051 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-2018-1000051/ (Markdown: https://insights.sbomify.com/CVE-2018-1000051/index.md)","id":"CVE-2018-1000051","markdown":"https://insights.sbomify.com/CVE-2018-1000051/index.md","name":"CVE-2018-1000051","record":{"aliases":["ALPINE-CVE-2018-1000051","DEBIAN-CVE-2018-1000051","GHSA-7m6m-78j4-h5p6","UBUNTU-CVE-2018-1000051"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"MuPDF library","requires_auth":"none","summary":"A use-after-free flaw in MuPDF allows attackers to execute code or cause denial of service when a victim opens a specially crafted PDF file.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mupdf","vendor":"artifex"},{"product":"debian_linux","vendor":"debian"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Artifex Mupdf version 1.12.0 contains a Use After Free vulnerability in fz_keep_key_storable that can result in DOS / Possible code execution.
