An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-43887 exists.\n\nAffected product: Struktur Libde265. 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-2023-43887/ (Markdown: https://insights.sbomify.com/CVE-2023-43887/index.md)","id":"CVE-2023-43887","markdown":"https://insights.sbomify.com/CVE-2023-43887/index.md","name":"CVE-2023-43887","record":{"aliases":["DEBIAN-CVE-2023-43887","GHSA-6xm3-xq5h-wg4m","UBUNTU-CVE-2023-43887"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"H.265 video codec library","requires_auth":"none","summary":"Buffer overflows in libde265 allow attackers to execute arbitrary code or cause denial of service via crafted video files.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libde265","vendor":"struktur"}],"cvss":{"score":8.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Libde265 v1.0.12 was discovered to contain multiple buffer overflows via the num_tile_columns and num_tile_row parameters in the function pic_parameter_set::dump.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Memory corruption in n/a","id":"CVE-2023-43887","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"struktur:libde265","products":["struktur:libde265"],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"Command injection in n/a","id":"CVE-2023-43890"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2023-43886"},"products":["n/a"],"published":"2023-11-22","related":[{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2023-49465","kev_date_added":null,"published":"2023-12-07"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2023-49467","kev_date_added":null,"published":"2023-12-07"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2023-49468","kev_date_added":null,"published":"2023-12-07"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2023-27103","kev_date_added":null,"published":"2023-03-15"},{"cvss_score":8.7,"headline":"NULL Pointer Dereference in libde265","id":"CVE-2026-33164","kev_date_added":null,"published":"2026-03-20"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2022-47664","kev_date_added":null,"published":"2023-03-03"}],"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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-26","vendors":["n/a"]},"summary":"Buffer overflows in libde265 allow attackers to execute arbitrary code or cause denial of service via crafted video files.","url":"https://insights.sbomify.com/CVE-2023-43887/"}
