An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2012-0947 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-2012-0947/ (Markdown: https://insights.sbomify.com/CVE-2012-0947/index.md)","id":"CVE-2012-0947","markdown":"https://insights.sbomify.com/CVE-2012-0947/index.md","name":"CVE-2012-0947","record":{"aliases":["DEBIAN-CVE-2012-0947","GHSA-mrcx-gg4f-hxqf"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Libav media library","requires_auth":"none","summary":"Remote attackers can execute arbitrary code or cause a crash via a crafted VQA media file due to a heap-based buffer overflow in Libav.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"canonical","cpe":[{"product":"libav","vendor":"libav"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Heap-based buffer overflow in the vqa_decode_chunk function in the VQA codec (vqavideo.c) in libavcodec in Libav 0.5.x before 0.5.9, 0.6.x before 0.6.6, 0.7.x before 0.7.6, and 0.8.x before 0.8.2 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted VQA media file in which the image size is not a multiple of the block size.","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":"Memory corruption in n/a","id":"CVE-2012-0947","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"libav:libav","products":["libav:libav"],"type":"memory_corruption","year":"2012"},"n_packages":0,"n_references":8,"next":{"headline":"Information disclosure in n/a","id":"CVE-2012-0948"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2012-0946"},"products":["n/a"],"published":"2012-08-20","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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code or cause a crash via a crafted VQA media file due to a heap-based buffer overflow in Libav.","url":"https://insights.sbomify.com/CVE-2012-0947/"}
