Descriptions

A vulnerability in the Portable Executable (PE) file scanning functionality of Clam AntiVirus (ClamAV) Software versions 0.101.1 and prior could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to a lack of proper input and validation checking mechanisms for PE files sent an affected device. An attacker could exploit this vulnerability by sending malformed PE files to the device running an affected version ClamAV Software. An 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 escaneado de archivos ejecutables portátiles (PE) del software Clam AntiVirus (ClamAV) versiones 0.101.1 y anteriores, podría permitir que un atacante remoto no autenticado cause una condición de denegación de servicio en un dispositivo afectado. La vulnerabilidad es debido a la falta de mecanismos de comprobación de entrada y validación apropiados para los archivos PE enviados al dispositivo afectado. Un atacante podría explotar esta vulnerabilidad enviando archivos PE malformados al dispositivo que ejecuta una versión afectada del software ClamAV. Una vulnerabilidad podría permitirle 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
