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-2021-25801 in the wild and no public exploit code.\n\nAffected product: Videolan Vlc Media Player. 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-2021-25801/ (Markdown: https://insights.sbomify.com/CVE-2021-25801/index.md)","id":"CVE-2021-25801","markdown":"https://insights.sbomify.com/CVE-2021-25801/index.md","name":"CVE-2021-25801","record":{"aliases":["DEBIAN-CVE-2021-25801","GHSA-vwcj-ffx4-g5rx","UBUNTU-CVE-2021-25801"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"VLC Media Player","requires_auth":"none","summary":"Attackers can cause an out-of-bounds read and potential crash in VLC Media Player by tricking users into opening a crafted AVI file.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"vlc_media_player","vendor":"videolan"}],"cvss":{"score":7.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"A buffer overflow vulnerability in the __Parse_indx component of VideoLAN VLC Media Player 3.0.11 allows attackers to cause an out-of-bounds read via a crafted .avi file.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2022-04-21","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2022-04-21T20:41:18Z","kind":"github_poc","ref":"https://github.com/DShankle/VLC_CVE-2021-25801_Analysis","stars":0,"title":null}],"tier":"poc_unverified"},"has_fix":true,"headline":"Memory corruption in n/a","id":"CVE-2021-25801","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"videolan:vlc_media_player","products":["videolan:vlc_media_player"],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2021-25802"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-25791"},"products":["n/a"],"published":"2021-07-26","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2008-0296","kev_date_added":null,"published":"2008-01-16"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-47359","kev_date_added":null,"published":"2023-11-07"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2019-12874","kev_date_added":null,"published":"2019-06-18"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-10699","kev_date_added":null,"published":"2017-06-30"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2013-1868","kev_date_added":null,"published":"2013-07-10"},{"cvss_score":9.3,"headline":"Use after free in n/a","id":"CVE-2012-0023","kev_date_added":null,"published":"2012-10-30"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2012-1775","kev_date_added":null,"published":"2012-03-19"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"Attackers can cause an out-of-bounds read and potential crash in VLC Media Player by tricking users into opening a crafted AVI file.","url":"https://insights.sbomify.com/CVE-2021-25801/"}
