The remote Ubuntu 24.04 LTS / 24.10 host has packages installed that are affected by a vulnerability as referenced in the USN-7229-1 advisory.

    It was discovered that ClamAV incorrectly handled decrypting OLE2 content. A remote attacker could     possibly use this issue to cause ClamAV to crash, resulting in a denial of service.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 1e109b60-d92e-11ef-a661-08002784c58d advisory.

    The ClamAV project reports:

                A possible buffer overflow read bug is found in the OLE2                 file parser that could cause a denial-of-service (DoS)                 condition.

According to its self-reported version, Cisco Secure Endpoint Connector for ClamAV is affected by a vulnerability.

  - 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. (CVE-2025-20128)
