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-2019-19721 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-2019-19721/ (Markdown: https://insights.sbomify.com/CVE-2019-19721/index.md)","id":"CVE-2019-19721","markdown":"https://insights.sbomify.com/CVE-2019-19721/index.md","name":"CVE-2019-19721","record":{"aliases":["DEBIAN-CVE-2019-19721","GHSA-2wrf-hf7j-cx32","UBUNTU-CVE-2019-19721"],"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":"Remote attackers can cause denial of service via memory corruption in VLC media player by exploiting an off-by-one error with a crafted image 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":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-193","name":"Off-by-one Error"}],"description":"An off-by-one error in the DecodeBlock function in codec/sdl_image.c in VideoLAN VLC media player before 3.0.9 allows remote attackers to cause a denial of service (memory corruption) via a crafted image file.
