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-2021-3504 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-2021-3504/ (Markdown: https://insights.sbomify.com/CVE-2021-3504/index.md)","id":"CVE-2021-3504","markdown":"https://insights.sbomify.com/CVE-2021-3504/index.md","name":"CVE-2021-3504","record":{"aliases":["AZL-6472","CLSA-2021-1624372464","DEBIAN-CVE-2021-3504","DLA-2656-1","DSA-4913-1","GHSA-5vp3-c6x6-5464","MGASA-2021-0320","OESA-2021-1200","RHSA-2021:2318","SUSE-SU-2021:1760-1","SUSE-SU-2021:1761-1","UBUNTU-CVE-2021-3504","USN-5148-1","USN-5148-2","openSUSE-SU-2021:0806-1","openSUSE-SU-2021:1761-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows registry parser","requires_auth":"none","summary":"A lack of bounds checking in the hivex library allows attackers to cause crashes or read out-of-bounds memory via crafted registry files.","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":"hivex","vendor":"redhat"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"A flaw was found in the hivex library in versions before 1.3.20.
