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-2023-49462 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-2023-49462/ (Markdown: https://insights.sbomify.com/CVE-2023-49462/index.md)","id":"CVE-2023-49462","markdown":"https://insights.sbomify.com/CVE-2023-49462/index.md","name":"CVE-2023-49462","record":{"aliases":["ALPINE-CVE-2023-49462","DEBIAN-CVE-2023-49462","GHSA-vhhj-cr5h-8r6h"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"HEIF image library","requires_auth":"none","summary":"A segmentation violation in libheif allows attackers to cause a denial of service via crafted HEIF images.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libheif","vendor":"struktur"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"libheif v1.17.5 was discovered to contain a segmentation violation via the component /libheif/exif.cc.","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-2023-49462","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Null dereference in n/a","id":"CVE-2023-49463"},"packages":[],"prev":{"headline":"Null dereference in n/a","id":"CVE-2023-49460"},"products":["n/a"],"published":"2023-12-07","related":[{"cvss_score":8.8,"headline":"libheif: Heap-Buffer-Overflow Write in Grid Tile Chroma Compositing","id":"CVE-2026-32740","kev_date_added":null,"published":"2026-05-19"},{"cvss_score":8.8,"headline":"Null dereference in n/a","id":"CVE-2023-49460","kev_date_added":null,"published":"2023-12-07"},{"cvss_score":8.8,"headline":"Null dereference in n/a","id":"CVE-2023-49463","kev_date_added":null,"published":"2023-12-07"},{"cvss_score":8.8,"headline":"Null dereference in n/a","id":"CVE-2023-49464","kev_date_added":null,"published":"2023-12-07"},{"cvss_score":8.8,"headline":"Denial of service in n/a","id":"CVE-2020-19498","kev_date_added":null,"published":"2021-07-21"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2020-19499","kev_date_added":null,"published":"2021-07-21"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-11-26","vendors":["n/a"]},"summary":"A segmentation violation in libheif allows attackers to cause a denial of service via crafted HEIF images.","url":"https://insights.sbomify.com/CVE-2023-49462/"}
