The remote Fedora 41 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2024-0d7eb64d90 advisory.

    Update to 1.0.7

    * CVE-2024-20506: Changed the logging module to disable following symlinks on Linux and Unix systems so as     to prevent an attacker with existing access to the 'clamd' or 'freshclam' services from using a symlink to     corrupt system files.
    * CVE-2024-20505: Fixed a possible out-of-bounds read bug in the PDF file parser that could cause a     denial-of-service (DoS) condition.


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

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

The version of clamav installed on the remote host is prior to 0.103.12-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2024-2644 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)
