Descriptions

A vulnerability in the Portable Document Format (PDF) scanning functionality of Clam AntiVirus (ClamAV) Software versions 0.101.1 and 0.101.0 could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a lack of proper data handling mechanisms within the device buffer while indexing remaining file data on an affected device. An attacker could exploit this vulnerability by sending crafted PDF files to an affected device. A successful exploit could allow the attacker to cause an out-of-bounds read condition, resulting in a crash that could result in a denial of service condition on an affected device.

Una vulnerabilidad en la funcionalidad de escaneo del Formato de Documento Portátil (PDF) de las versiones 0.101.1 y 0.101.0 del software Clam AntiVirus (ClamAV), podría permitir que un atacante remoto no autenticado cause una condición de denegación de servicio (DoS) en un dispositivo afectado. La vulnerabilidad es debido a la falta de mecanismos apropiados de manejo de datos dentro del búfer del dispositivo cuando se indexan los datos de archivo restantes en un dispositivo afectado. Un atacante podría explotar esta vulnerabilidad mediante el envío archivos PDF creados a un dispositivo afectado. Una explotación con éxito podría permitir al atacante causar una condición de lectura fuera de límites, resultando en un bloqueo que podría generar una condición de denegación de servicio en un dispositivo afectado.
