## Description

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 in the message parsing function on an affected system.
An unauthenticated, remote attacker could exploit this vulnerability by
sending a crafted email to the affected device. This action could cause a
messageAddArgument (in message.c) buffer overflow condition when ClamAV
scans the malicious email, allowing the attacker to potentially cause a DoS
condition or execute arbitrary code on an affected device.
