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.
