https://notcve.org/view.php?id=CVE-2017-12380
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 improper input validation checking mechanisms in mbox.c during certain mail parsing functions of the ClamAV software. An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted email to the affected device. An exploit could trigger a NULL pointer dereference condition when ClamAV scans the malicious email, which may result in a DoS condition. ClamAV AntiVirus, en versiones 0.99.2 y anteriores, contiene una vulnerabilidad que podría permitir que un atacante remoto sin autenticar provoque una denegación de servicio (DoS) en un sistema afectado. • http://blog.clamav.net/2018/01/clamav-0993-has-been-released.html https://bugzilla.clamav.net/show_bug.cgi?id=11945 https://lists.debian.org/debian-lts-announce/2018/01/msg00035.html https://usn.ubuntu.com/3550-1 https://usn.ubuntu.com/3550-2 • CWE-476: NULL Pointer Dereference •

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. ClamAV AntiVirus, en versiones 0.99.2 y anteriores, contiene una vulnerabilidad que podría permitir que un atacante remoto sin autenticar provoque una denegación de servicio (DoS) en un sistema afectado. La vulnerabilidad se debe a la falta de mecanismos de comprobación de validación de entradas durante ciertas operaciones de análisis de email (operaciones mbox.c en mensajes devueltos). • http://blog.clamav.net/2018/01/clamav-0993-has-been-released.html https://bugzilla.clamav.net/show_bug.cgi?id=11939 https://lists.debian.org/debian-lts-announce/2018/01/msg00035.html https://usn.ubuntu.com/3550-1 https://usn.ubuntu.com/3550-2 • CWE-416: Use After Free •
