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-2023-46426 exists.\n\nAffected product: Gpac Gpac. 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-2023-46426/ (Markdown: https://insights.sbomify.com/CVE-2023-46426/index.md)","id":"CVE-2023-46426","markdown":"https://insights.sbomify.com/CVE-2023-46426/index.md","name":"CVE-2023-46426","record":{"aliases":["DEBIAN-CVE-2023-46426","GHSA-3ppx-w77w-7jj2","UBUNTU-CVE-2023-46426"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"GPAC multimedia library","requires_auth":"none","summary":"Remote attackers can execute arbitrary code or cause denial of service via a heap-based buffer overflow in the GPAC multimedia library.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"gpac","vendor":"gpac"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"Heap-based Buffer Overflow vulnerability in gpac version 2.3-DEV-rev588-g7edc40fee-master, allows remote attackers to execute arbitrary code and cause a denial of service (DoS) via gf_fwrite component in at utils/os_file.c.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Memory corruption in n/a","id":"CVE-2023-46426","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"gpac:gpac","products":["gpac:gpac"],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Null dereference in n/a","id":"CVE-2023-46427"},"packages":[],"prev":{"headline":"Command injection in n/a","id":"CVE-2023-46424"},"products":["n/a"],"published":"2024-03-09","related":[{"cvss_score":9.8,"headline":"Null dereference in n/a","id":"CVE-2023-46427","kev_date_added":null,"published":"2024-03-09"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-46932","kev_date_added":null,"published":"2023-12-09"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2022-36190","kev_date_added":null,"published":"2022-08-17"},{"cvss_score":9.8,"headline":"Null dereference in n/a","id":"CVE-2021-28300","kev_date_added":null,"published":"2021-04-14"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2020-11558","kev_date_added":null,"published":"2020-04-05"},{"cvss_score":9.1,"headline":"Memory corruption in n/a","id":"CVE-2020-19751","kev_date_added":null,"published":"2021-09-07"}],"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":"total"},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code or cause denial of service via a heap-based buffer overflow in the GPAC multimedia library.","url":"https://insights.sbomify.com/CVE-2023-46426/"}
