FreeBSD : clamav -- Possible crash in the HTML file parser that could cause a denial-of-service (DoS) condition (ecafc4af-fe8a-11ee-890c-08002784c58d)

high Nessus Plugin ID 193663



The remote FreeBSD host is missing one or more security-related updates.


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 ecafc4af-fe8a-11ee-890c-08002784c58d advisory.

- A vulnerability in the HTML parser of ClamAV could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to an issue in the C to Rust foreign function interface. An attacker could exploit this vulnerability by submitting a crafted file containing HTML content to be scanned by ClamAV on an affected device. An exploit could allow the attacker to cause the ClamAV scanning process to terminate, resulting in a DoS condition on the affected software.

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


Update the affected packages.
