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-2021-36081 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-36081/ (Markdown: https://insights.sbomify.com/CVE-2021-36081/index.md)","id":"CVE-2021-36081","markdown":"https://insights.sbomify.com/CVE-2021-36081/index.md","name":"CVE-2021-36081","record":{"aliases":["DEBIAN-CVE-2021-36081","GHSA-5x29-fwcc-jm29","UBUNTU-CVE-2021-36081"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Tesseract OCR library","requires_auth":"none","summary":"A use-after-free vulnerability in Tesseract OCR allows attackers to potentially execute arbitrary code or cause a denial of service via crafted input.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"tesseract_ocr","vendor":"tesseract-ocr"}],"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-416","name":"Use After Free"}],"description":"Tesseract OCR 5.0.0-alpha-20201231 has a one_ell_conflict use-after-free during a strpbrk call.","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":"Use after free in n/a","id":"CVE-2021-36081","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Memory corruption in n/a","id":"CVE-2021-36082"},"packages":[],"prev":{"headline":"Use after free in n/a","id":"CVE-2021-36080"},"products":["n/a"],"published":"2021-07-01","related":[{"cvss_score":8.6,"headline":"Tesseract: ReadNormProtos stack buffer overflow","id":"CVE-2026-88047","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":8.6,"headline":"Tesseract: Heap out-of-bounds write/read in FullyConnected::Forward via layer/weight-matrix dimension mismatch","id":"CVE-2026-88048","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":8.6,"headline":"Tesseract: Heap out-of-bounds write in LSTM::Forward via na_/gate-matrix dimension mismatch","id":"CVE-2026-88049","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":8.6,"headline":"Tesseract: Heap out-of-bounds write in GenericVector\u003cT\u003e::read due to independent reserved/size_used_ fields","id":"CVE-2026-88051","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":8.6,"headline":"Tesseract: Heap out-of-bounds write in Classify::ReadIntTemplates via unvalidated counts in crafted .traineddata","id":"CVE-2026-88053","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":7.8,"headline":"Tesseract: Heap out-of-bounds write in UNICHARSET::load_via_fgets via count/insert desynchronization","id":"CVE-2026-88052","kev_date_added":null,"published":"2026-09-10"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"A use-after-free vulnerability in Tesseract OCR allows attackers to potentially execute arbitrary code or cause a denial of service via crafted input.","url":"https://insights.sbomify.com/CVE-2021-36081/"}
