CVE-2025-20128 (GCVE-0-2025-20128)

Vulnerability from cvelistv5 – Published: 2025-01-22 16:21 – Updated: 2025-11-03 18:08

Title

ClamAV OLE2 File Format Decryption Denial of Service Vulnerability

Summary

A vulnerability in the Object Linking and Embedding 2 (OLE2) decryption routine of ClamAV could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to an integer underflow in a bounds check that allows for a heap buffer overflow read. 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 . Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
