F-Secure Linux Security (32-bit)  F-Secure Linux Security 64  F-Secure Atlant  F-Secure Cloud Protection for Salesforce, published on 7 Sep 2021. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-33599 in the wild and no public exploit code.\n\nAffected product: F-Secure endpoint protection products on Windows and Mac. F-Secure Linux Security (32-bit)  F-Secure Linux Security 64  F-Secure Atlant  F-Secure Cloud Protection for Salesforce. 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-2021-33599/ (Markdown: https://insights.sbomify.com/CVE-2021-33599/index.md)","id":"CVE-2021-33599","markdown":"https://insights.sbomify.com/CVE-2021-33599/index.md","name":"CVE-2021-33599","record":{"aliases":["GHSA-6f5f-78pr-p7q9"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"F-Secure Antivirus","requires_auth":"low_privilege","summary":"Remote attackers can cause a denial of service in F-Secure Antivirus engines by submitting malicious WIM archive files, leading to infinite loops and freezing the scanner.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"F-SecureUS","cpe":[{"product":"atlant","vendor":"f-secure"},{"product":"cloud_protection_for_salesforce","vendor":"f-secure"},{"product":"elements_endpoint_protection","vendor":"f-secure"},{"product":"linux_security","vendor":"f-secure"}],"cvss":{"score":4.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-835","name":"Loop with Unreachable Exit Condition"}],"description":"A vulnerability affecting F-Secure Antivirus engine was discovered whereby scanning WIM archive file can lead to denial-of-service (infinite loop and freezes AV engine scanner).
