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-2021-3630 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-2021-3630/ (Markdown: https://insights.sbomify.com/CVE-2021-3630/index.md)","id":"CVE-2021-3630","markdown":"https://insights.sbomify.com/CVE-2021-3630/index.md","name":"CVE-2021-3630","record":{"aliases":["CLEANSTART-2023-SN97100","DEBIAN-CVE-2021-3630","DLA-2702-1","GHSA-mpc3-cw77-gc2f","OESA-2021-1266","SUSE-SU-2021:14761-1","SUSE-SU-2021:14773-1","SUSE-SU-2021:2619-1","SUSE-SU-2021:2621-1","SUSE-SU-2021:2796-1","UBUNTU-CVE-2021-3630","USN-5005-1","openSUSE-SU-2021:1112-1","openSUSE-SU-2021:2619-1","openSUSE-SU-2024:12946-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"DjVuLibre library","requires_auth":"none","summary":"An out-of-bounds write in DjVuLibre allows attackers to cause a crash via crafted DjVu files, impacting applications using the library.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fedora","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"djvulibre","vendor":"djvulibre_project"},{"product":"fedora","vendor":"fedoraproject"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"An out-of-bounds write vulnerability was found in DjVuLibre in DJVU::DjVuTXT::decode() in DjVuText.cpp via a crafted djvu file which may lead to crash and segmentation fault.
