Critical
MetricsAV:N/AC:L/Au:N/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions ClamAV AntiVirus software versions 0.99.2 and prior
Description The issue is due to improper input validation checking mechanisms in the message parsing function, specifically the messageAddArgument function in message.c, which can lead to a buffer overflow condition. An unauthenticated, remote attacker could exploit this by sending a crafted email to the affected device, potentially causing a denial of service condition or executing arbitrary code.
Recommendations For ClamAV AntiVirus software versions 0.99.2 and prior, consider updating to a version that addresses the improper input validation in the message parsing function to prevent potential exploitation. As a temporary workaround, consider restricting the handling of emails by ClamAV to minimize the risk of exploitation until a patch is available.
