The 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 on an affected device. The vulnerability is due to a lack of input validation checking mechanisms during certain mail parsing operations (mbox.c operations on bounce messages). If successfully exploited, the ClamAV software could allow a variable pointing to the mail body which could cause a used after being free (use-after-free) instance which may lead to a disruption of services on an affected device to include a denial of service condition.

Security readout for executives and security teams

ClamAV 0.99.2 and earlier can be disrupted when parsing certain email bounce messages. A remote unauthenticated attacker could cause denial of service, affecting systems that rely on ClamAV for mail or file scanning availability. Exposure is most likely where ClamAV 0.99.2 or older processes untrusted email, especially mbox or bounce-message content. Mail gateways, content filters, and servers using distribution ClamAV packages from the affected era should be checked. Treat as a patching priority for email security infrastructure. Business risk is service disruption in malware scanning or mail processing, not confirmed compromise. Aging ClamAV installations should be upgraded promptly. Mitigation focus: Upgrade ClamAV beyond 0.99.2 or apply vendor security updates.; Follow Ubuntu, Debian, or ClamAV advisory guidance for supported packages.; Prioritize mail-scanning systems that process untrusted messages..
