Descriptions
clamscan in ClamAV before 0.99.4 contains a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition 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 an out-of-bounds read when ClamAV scans the malicious file, allowing the attacker to cause a DoS condition. This concerns pdf_parse_array and pdf_parse_string in libclamav/pdfng.c. Cisco Bug IDs: CSCvh91380, CSCvh91400.
clamscan en ClamAV, en versiones anteriores a la 0.99.4, contiene una vulnerabilidad que podría permitir que un atacante remoto sin autenticar provoque una denegación de servicio (DoS) 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 una lectura fuera de límites cuando ClamAV escanea el archivo malicioso, lo que permitiría que el atacante provocase un DoS. Esto afecta a pdf_parse_array y pdf_parse_string en libclamav/pdfng.c. Cisco Bug IDs: CSCvh91380, CSCvh91400.
