CVE-2025-20128 · ClamAV OLE2 File Format Decryption Denial of Service Vulnerability

This page contains facts from public vulnerability sources. Check the original advisory before updating.

An attacker could exploit this vulnerability by submitting a crafted file containing OLE2 content to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to terminate the ClamAV scanning process, resulting in a DoS condition on the affected software. For a description of this vulnerability, see the .
