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-2020-27824 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-2020-27824/ (Markdown: https://insights.sbomify.com/CVE-2020-27824/index.md)","id":"CVE-2020-27824","markdown":"https://insights.sbomify.com/CVE-2020-27824/index.md","name":"CVE-2020-27824","record":{"aliases":["ALPINE-CVE-2020-27824","AZL-45282","DEBIAN-CVE-2020-27824","GHSA-4w56-x77j-f3vc","JLSEC-2026-537","UBUNTU-CVE-2020-27824"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OpenJPEG image library","requires_auth":"none","summary":"An attacker can cause a buffer overflow in OpenJPEG's encoder via crafted input, leading to a denial of service.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"enterprise_linux","vendor":"redhat"},{"product":"openjpeg","vendor":"uclouvain"}],"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-125","name":"Out-of-bounds Read"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A flaw was found in OpenJPEG’s encoder in the opj_dwt_calc_explicit_stepsizes() function.
