It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2024-737 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)

    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-2024-20506)

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

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