An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-19857 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. 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-2018-19857/ (Markdown: https://insights.sbomify.com/CVE-2018-19857/index.md)","id":"CVE-2018-19857","markdown":"https://insights.sbomify.com/CVE-2018-19857/index.md","name":"CVE-2018-19857","record":{"aliases":["DEBIAN-CVE-2018-19857","DSA-4366-1","GHSA-7g6v-cgr9-2355","UBUNTU-CVE-2018-19857"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"VLC media player","requires_auth":"none","summary":"An attacker can cause a denial of service or information leak in VLC media player by tricking a user into opening a maliciously crafted CAF file.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"vlc_media_player","vendor":"videolan"}],"cvss":{"score":9.1,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-824","name":"Access of Uninitialized Pointer"}],"description":"The CAF demuxer in modules/demux/caf.c in VideoLAN VLC media player 3.0.4 may read memory from an uninitialized pointer when processing magic cookies in CAF files, because a ReadKukiChunk() cast converts a return value to an unsigned int even if that value is negative.
