{"id":"CVE-2023-20197","details":"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. An attacker could exploit this vulnerability by submitting a crafted HFS+ filesystem image to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to cause the ClamAV scanning process to stop responding, resulting in a DoS condition on the affected software and consuming available system resources.\r\n\r For a description of this vulnerability, see the ClamAV blog .","modified":"2026-03-13T06:52:10.344497Z","published":"2023-08-16T22:15:10.510Z","related":["MGASA-2023-0257","SUSE-SU-2023:3435-1","SUSE-SU-2023:3456-1","SUSE-SU-2025:0325-1","SUSE-SU-2025:0327-1","SUSE-SU-2025:0328-1","openSUSE-SU-2024:13174-1"],"references":[{"type":"ADVISORY","url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-clamav-rNwNEEee"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"1.22.0"}]},{"events":[{"introduced":"0"},{"fixed":"1.22.0"}]},{"events":[{"introduced":"0"},{"fixed":"7.5.13.21586"}]},{"events":[{"introduced":"8.0.1.21160"},{"fixed":"8.1.7.21585"}]},{"events":[{"introduced":"0"},{"fixed":"3.8.0"}]},{"events":[{"introduced":"0"},{"last_affected":"38"}]}],"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-20197.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
