The version of clamav installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-20505 advisory.

  - A vulnerability in the PDF parsing module of Clam AntiVirus (ClamAV) versions 1.4.0, 1.3.2 and prior     versions, all 1.2.x versions, 1.0.6 and prior versions, all 0.105.x versions, all 0.104.x versions, and     0.103.11 and all prior versions could allow an unauthenticated, remote attacker to cause a denial of     service (DoS) condition on an affected device. The vulnerability is due to an out of bounds read. An     attacker could exploit this vulnerability by submitting a crafted PDF file to be scanned by ClamAV on an     affected device. An exploit could allow the attacker to terminate the scanning process. (CVE-2024-20505)

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0012 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2024-20506:
    A vulnerability in the ClamD service module of Clam AntiVirus (ClamAV) versions 1.4.0, 1.3.2 and prior     versions, all 1.2.x versions, 1.0.6 and prior versions, all 0.105.x versions, all 0.104.x versions, and     0.103.11 and all prior versions could allow an authenticated, local attacker to corrupt critical system     files.

    The vulnerability is due to allowing the ClamD process to write to its log file while privileged without     checking if the logfile has been replaced with a symbolic link. 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.

    CVE-2024-20505:
    A vulnerability in the PDF parsing module of Clam AntiVirus (ClamAV) versions 1.4.0, 1.3.2 and prior     versions, all 1.2.x versions, 1.0.6 and prior versions, all 0.105.x versions, all 0.104.x versions, and     0.103.11 and all prior versions could allow an unauthenticated, remote attacker to cause a denial of     service (DoS) condition on an affected device.

    The vulnerability is due to an out of bounds read. An attacker could exploit this vulnerability by     submitting a crafted PDF file to be scanned by ClamAV on an affected device. An exploit could allow the     attacker to terminate the scanning process.
