An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-20248 in the wild and no public exploit code.\n\nAffected product: Foxit Quick PDF Library. 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-2018-20248/ (Markdown: https://insights.sbomify.com/CVE-2018-20248/index.md)","id":"CVE-2018-20248","markdown":"https://insights.sbomify.com/CVE-2018-20248/index.md","name":"CVE-2018-20248","record":{"aliases":["GHSA-mqg6-4mpr-wf6p"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PDF processing library","requires_auth":"none","summary":"Attackers can trigger out-of-bounds memory access via malformed PDFs, potentially leading to code execution or crashes in applications using the library.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"checkpoint","cpe":[{"product":"quick_pdf_library","vendor":"foxitsoftware"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"},{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"In Foxit Quick PDF Library (all versions prior to 16.12), issue where loading a malformed or malicious PDF containing invalid xref table pointers or invalid xref table data using the LoadFromFile, LoadFromString, LoadFromStream, DAOpenFile or DAOpenFileReadOnly functions may result in an access violation caused by out of bounds memory access.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Memory corruption in Foxit Quick PDF Library","id":"CVE-2018-20248","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Memory corruption in Foxit Quick PDF Library","id":"CVE-2018-20249"},"packages":[],"prev":{"headline":"Denial of service in Foxit Quick PDF Library","id":"CVE-2018-20247"},"products":["Foxit Quick PDF Library"],"published":"2018-12-24","related":[{"cvss_score":8.8,"headline":"Memory corruption in Foxit Quick PDF Library","id":"CVE-2018-20249","kev_date_added":null,"published":"2018-12-24"},{"cvss_score":7.8,"headline":"Denial of service in Foxit Quick PDF Library","id":"CVE-2018-20247","kev_date_added":null,"published":"2018-12-24"}],"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":"Attackers can trigger out-of-bounds memory access via malformed PDFs, potentially leading to code execution or crashes in applications using the library.","url":"https://insights.sbomify.com/CVE-2018-20248/"}
