Descriptions

A vulnerability in the Data-Loss-Prevention (DLP) module in Clam AntiVirus (ClamAV) Software versions 0.102.1 and 0.102.0 could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to an out-of-bounds read affecting users that have enabled the optional DLP feature. An attacker could exploit this vulnerability by sending a crafted email file to an affected device. An exploit could allow the attacker to cause the ClamAV scanning process crash, resulting in a denial of service condition.

Una vulnerabilidad en el módulo Data-Loss-Prevention (DLP) en el software Clam AntiVirus (ClamAV) versiones 0.102.1 y 0.102.0, podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio sobre un dispositivo afectado. La vulnerabilidad es debido a una lectura fuera de límites afectando a usuarios que han habilitado la funcionalidad opcional DLP. Un atacante podría explotar esta vulnerabilidad mediante el envío de un archivo de correo electrónico diseñado hacia un dispositivo afectado. Una explotación podría permitir al atacante causar el bloqueo del proceso de escaneo de ClamAV, resultando en una condición de denegación de servicio.

USN-4280-1 fixed a vulnerability in ClamAV. This update provides the corresponding update for Ubuntu 12.04 ESM and Ubuntu 14.04 ESM. It was discovered that ClamAV incorrectly handled memory when the Data-Loss-Prevention feature was enabled. A remote attacker could possibly use this issue to cause ClamAV to crash, resulting in a denial of service. Various other issues were also addressed.
