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-2018-19762 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2018-19762/ (Markdown: https://insights.sbomify.com/CVE-2018-19762/index.md)","id":"CVE-2018-19762","markdown":"https://insights.sbomify.com/CVE-2018-19762/index.md","name":"CVE-2018-19762","record":{"aliases":["DEBIAN-CVE-2018-19762","GHSA-f8f7-6788-54wv","UBUNTU-CVE-2018-19762"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Sixel image library","requires_auth":"none","summary":"A heap-based buffer overflow in libsixel allows attackers to cause denial of service or potentially execute arbitrary code via crafted images.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libsixel","vendor":"saitoha"}],"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-787","name":"Out-of-bounds Write"}],"description":"There is a heap-based buffer overflow at fromsixel.c (function: image_buffer_resize) in libsixel 1.8.2 that will cause a denial of service or possibly unspecified other impact.","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":"Memory corruption in n/a","id":"CVE-2018-19762","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2018-19763"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2018-19761"},"products":["n/a"],"published":"2018-11-30","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-19635","kev_date_added":null,"published":"2019-12-08"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2019-19636","kev_date_added":null,"published":"2019-12-08"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2019-19637","kev_date_added":null,"published":"2019-12-08"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2019-19638","kev_date_added":null,"published":"2019-12-08"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2022-27044","kev_date_added":null,"published":"2022-04-08"},{"cvss_score":8.8,"headline":"Use after free in n/a","id":"CVE-2022-27046","kev_date_added":null,"published":"2022-04-08"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2020-21547","kev_date_added":null,"published":"2021-09-17"}],"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":"2024-09-16","vendors":["n/a"]},"summary":"A heap-based buffer overflow in libsixel allows attackers to cause denial of service or potentially execute arbitrary code via crafted images.","url":"https://insights.sbomify.com/CVE-2018-19762/"}
