Descriptions

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.

Una vulnerabilidad en el analizador HTML de ClamAV podría permitir que un atacante remoto no autenticado provoque una condición de denegación de servicio (DoS) en un dispositivo afectado. La vulnerabilidad se debe a un problema en la interfaz de función externa de C a Rust. Un atacante podría aprovechar esta vulnerabilidad enviando un archivo manipulado que contenga contenido HTML para que ClamAV lo analice en un dispositivo afectado. Un exploit podría permitir al atacante provocar que finalice el proceso de escaneo de ClamAV, lo que resultaría en una condición DoS en el software afectado.
