Descriptions

ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition or potentially execute arbitrary code on an affected device. The vulnerability is due to improper input validation checking mechanisms when handling Portable Document Format (.pdf) files sent to an affected device. An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted .pdf file to an affected device. This action could cause a handle_pdfname (in pdf.c) buffer overflow when ClamAV scans the malicious file, allowing the attacker to cause a DoS condition or potentially execute arbitrary code.

ClamAV AntiVirus, en versiones 0.99.2 y anteriores, contiene una vulnerabilidad que podría permitir que un atacante remoto sin autenticar provoque una denegación de servicio (DoS) o ejecute código arbitrario en un sistema afectado. La vulnerabilidad se debe a errores en los mecanismos de comprobación de validación de entradas al gestionar los archivos Portable Document Format (.pdf) enviados a un dispositivo afectado. Un atacante remoto no autenticado podría explotar esta vulnerabilidad enviando un archivo .pdf manipulado a un dispositivo afectado. Esta acción podría provocar un desbordamiento de búfer en handle_pdfname (en pdf.c) cuando ClamAV escanea el archivo malicioso, permitiendo que el atacante cree una condición de DoS o ejecute código arbitrario.
