An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-1404 in the wild and no public exploit code.\n\nAffected product: Clamav Clamav. 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-2021-1404/ (Markdown: https://insights.sbomify.com/CVE-2021-1404/index.md)","id":"CVE-2021-1404","markdown":"https://insights.sbomify.com/CVE-2021-1404/index.md","name":"CVE-2021-1404","record":{"aliases":["ALPINE-CVE-2021-1404","CLEANSTART-2026-GW53162","DEBIAN-CVE-2021-1404","GHSA-95rx-jp6p-3cmx","UBUNTU-CVE-2021-1404"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"ClamAV antivirus","requires_auth":"none","summary":"A remote attacker can cause a denial of service in ClamAV by sending a crafted PDF file that triggers a heap buffer over-read.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"clamav","vendor":"clamav"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/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 vulnerability in the PDF parsing module in Clam AntiVirus (ClamAV) Software versions 0.103.0 and 0.103.1 could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device.
