An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-20363 in the wild and no public exploit code.\n\nAffected product: Libraw Libraw. 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-2018-20363/ (Markdown: https://insights.sbomify.com/CVE-2018-20363/index.md)","id":"CVE-2018-20363","markdown":"https://insights.sbomify.com/CVE-2018-20363/index.md","name":"CVE-2018-20363","record":{"aliases":["DEBIAN-CVE-2018-20363","GHSA-7654-46v5-gj2h","UBUNTU-CVE-2018-20363"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"LibRaw image library","requires_auth":"none","summary":"A NULL pointer dereference in LibRaw allows attackers to cause a denial of service via crafted image files.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libraw","vendor":"libraw"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"LibRaw::raw2image in libraw_cxx.cpp in LibRaw 0.19.1 has a NULL pointer dereference.","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":"Null dereference in n/a","id":"CVE-2018-20363","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"libraw:libraw","products":["libraw:libraw"],"type":"null_dereference","year":"2018"},"n_packages":0,"n_references":3,"next":{"headline":"Null dereference in n/a","id":"CVE-2018-20364"},"packages":[],"prev":{"headline":"Null dereference in n/a","id":"CVE-2018-20362"},"products":["n/a"],"published":"2018-12-22","related":[{"cvss_score":9.8,"headline":"Memory corruption in LibRaw","id":"CVE-2026-20889","kev_date_added":null,"published":"2026-04-07"},{"cvss_score":9.8,"headline":"Memory corruption in LibRaw","id":"CVE-2026-20911","kev_date_added":null,"published":"2026-04-07"},{"cvss_score":9.8,"headline":"Memory corruption in LibRaw","id":"CVE-2026-21413","kev_date_added":null,"published":"2026-04-07"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2015-8366","kev_date_added":null,"published":"2020-01-14"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2015-8367","kev_date_added":null,"published":"2020-01-14"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-14265","kev_date_added":null,"published":"2017-09-11"},{"cvss_score":9.8,"headline":"Memory corruption in LibRaw","id":"CVE-2017-6886","kev_date_added":null,"published":"2017-05-16"}],"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":"A NULL pointer dereference in LibRaw allows attackers to cause a denial of service via crafted image files.","url":"https://insights.sbomify.com/CVE-2018-20363/"}
