Severity ?
5.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
Summary
A vulnerability in the Object Linking and Embedding 2 (OLE2) decryption routine of ClamAV could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to an integer underflow in a bounds check that allows for a heap buffer overflow read. An attacker could exploit this vulnerability by submitting a crafted file containing OLE2 content to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to terminate the ClamAV scanning process, resulting in a DoS condition on the affected software. For a description of this vulnerability, see the . Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Esta vulnerabilidad se debe a un desbordamiento de enteros en una comprobación de los límites que permite una lectura de desbordamiento de búfer de montón. Un atacante podría aprovechar esta vulnerabilidad enviando un archivo manipulado con contenido OLE2 para que ClamAV lo escanee en un dispositivo afectado. Una explotación exitosa podría permitir al atacante terminar el proceso de escaneo de ClamAV, lo que provocaría una condición de denegación de servicio (DoS) en el software afectado.
