An attacker could exploit this vulnerability if they replace the ClamD log file with a symlink to a critical system file and then find a way to restart the ClamD process. An exploit could allow the attacker to corrupt a critical system file by appending ClamD log messages after restart.","severity":{"version":"3.1","score":6.1,"vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-12","score":0.00318,"percentile":0.25049,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-754"],"published":"2024-09-04T21:28:54Z","modified":"2026-11-05T05:40:51Z","fixes":[{"ecosystem":"Alpine:v3.21","package":"clamav","fixed_in":["1.3.2-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.22","package":"clamav","fixed_in":["1.3.2-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.23","package":"clamav","fixed_in":["1.3.2-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.24","package":"clamav","fixed_in":["1.3.2-r0"],"sources":["osv"]},{"ecosystem":"Azure
