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-2017-16803 in the wild and no public exploit code.\n\nAffected product: Libav Libav. 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-2017-16803/ (Markdown: https://insights.sbomify.com/CVE-2017-16803/index.md)","id":"CVE-2017-16803","markdown":"https://insights.sbomify.com/CVE-2017-16803/index.md","name":"CVE-2017-16803","record":{"aliases":["DEBIAN-CVE-2017-16803","DSA-4119-1","GHSA-j8rq-pgqm-7hx7","UBUNTU-CVE-2017-16803"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Libav multimedia library","requires_auth":"none","summary":"Remote attackers can cause a denial of service via a crafted Smacker stream due to improper tree recursion restrictions in Libav.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libav","vendor":"libav"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"In Libav through 11.11 and 12.x through 12.1, the smacker_decode_tree function in libavcodec/smacker.c does not properly restrict tree recursion, which allows remote attackers to cause a denial of service (bitstream.c:build_table() out-of-bounds read and application crash) via a crafted Smacker stream.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Denial of service in n/a","id":"CVE-2017-16803","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"libav:libav","products":["libav:libav"],"type":"denial_of_service","year":"2017"},"n_packages":0,"n_references":5,"next":{"headline":"Information disclosure in n/a","id":"CVE-2017-16804"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2017-16802"},"products":["n/a"],"published":"2017-11-13","related":[{"cvss_score":10,"headline":"Multiple unspecified vulnerabilities in Libav before 0.8.12 allow remote attackers to have unknown impact and vectors.","id":"CVE-2014-3984","kev_date_added":null,"published":"2014-06-06"},{"cvss_score":9.8,"headline":"Null dereference in n/a","id":"CVE-2017-9051","kev_date_added":null,"published":"2017-05-18"},{"cvss_score":8.8,"headline":"Integer overflow in n/a","id":"CVE-2014-4609","kev_date_added":null,"published":"2020-01-14"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2019-9719","kev_date_added":null,"published":"2019-09-19"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2018-5766","kev_date_added":null,"published":"2018-01-18"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2018-5684","kev_date_added":null,"published":"2018-01-14"},{"cvss_score":8.8,"headline":"Null dereference in n/a","id":"CVE-2017-17129","kev_date_added":null,"published":"2017-12-04"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Remote attackers can cause a denial of service via a crafted Smacker stream due to improper tree recursion restrictions in Libav.","url":"https://insights.sbomify.com/CVE-2017-16803/"}
