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-2017-9051 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-2017-9051/ (Markdown: https://insights.sbomify.com/CVE-2017-9051/index.md)","id":"CVE-2017-9051","markdown":"https://insights.sbomify.com/CVE-2017-9051/index.md","name":"CVE-2017-9051","record":{"aliases":["DEBIAN-CVE-2017-9051","GHSA-93m5-m7h3-h2pm","UBUNTU-CVE-2017-9051"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"libav media library","requires_auth":"none","summary":"A NULL pointer dereference in libav allows attackers to cause a denial of service via crafted NSV files.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libav","vendor":"libav"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"libav before 12.1 is vulnerable to an invalid read of size 1 due to NULL pointer dereferencing in the nsv_read_chunk function in libavformat/nsvdec.c.","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":"Null dereference in n/a","id":"CVE-2017-9051","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"libav:libav","products":["libav:libav"],"type":"null_dereference","year":"2017"},"n_packages":0,"n_references":3,"next":{"headline":"Memory corruption in n/a","id":"CVE-2017-9052"},"packages":[],"prev":{"headline":"Out-of-bounds read in nokogiri","id":"CVE-2017-9050"},"products":["n/a"],"published":"2017-05-18","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":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":"A NULL pointer dereference in libav allows attackers to cause a denial of service via crafted NSV files.","url":"https://insights.sbomify.com/CVE-2017-9051/"}
