An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-20197 and fix it if it is affected.\n\nWhat it is: CVE-2023-20197 is a high-severity denial of service vulnerability in Fedoraproject Fedora, published on 16 Aug 2023. 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-2023-20197 in the wild and no public exploit code.\n\nAffected product: Fedoraproject Fedora. 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-2023-20197/ (Markdown: https://insights.sbomify.com/CVE-2023-20197/index.md)","id":"CVE-2023-20197","markdown":"https://insights.sbomify.com/CVE-2023-20197/index.md","name":"CVE-2023-20197","record":{"aliases":["CLEANSTART-2026-MF37680","DEBIAN-CVE-2023-20197","DLA-3544-1","GHSA-r7mw-p665-4533","OESA-2023-1540","OESA-2023-1557","OESA-2023-1558","OESA-2023-1559","OESA-2023-1560","SUSE-SU-2023:3435-1","SUSE-SU-2023:3456-1","UBUNTU-CVE-2023-20197","USN-6303-1","USN-6303-2","openSUSE-SU-2024:13174-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"ClamAV antivirus engine","requires_auth":"none","summary":"An unauthenticated remote attacker can cause a denial of service in ClamAV by submitting a crafted HFS+ filesystem image that triggers an infinite loop during decompression.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"secure_endpoint","vendor":"cisco"},{"product":"secure_endpoint_private_cloud","vendor":"cisco"},{"product":"fedora","vendor":"fedoraproject"}],"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-835","name":"Loop with Unreachable Exit Condition"}],"description":"A vulnerability in the filesystem image parser for Hierarchical File System Plus (HFS+) of ClamAV could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.\r\n\r This vulnerability is due to an incorrect check for completion when a file is decompressed, which may result in a loop condition that could cause the affected software to stop responding.
