https://notcve.org/view.php?id=CVE-2017-12379
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. 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) o ejecute código arbitrario en un sistema afectado. • http://blog.clamav.net/2018/01/clamav-0993-has-been-released.html https://bugzilla.clamav.net/show_bug.cgi?id=11944 https://lists.debian.org/debian-lts-announce/2018/01/msg00035.html https://usn.ubuntu.com/3550-1 https://usn.ubuntu.com/3550-2 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

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 mew packet files sent to an affected device. A successful exploit could cause a heap-based buffer over-read condition in mew.c when ClamAV scans the malicious file, allowing the attacker to cause a DoS condition or potentially execute arbitrary code on the affected device. 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) o ejecute código arbitrario en un sistema afectado. La vulnerabilidad se debe a errores en los mecanismos de comprobación de validación de entradas en archivos mew packet enviados a un dispositivo afectado. • http://blog.clamav.net/2018/01/clamav-0993-has-been-released.html https://bugzilla.clamav.net/show_bug.cgi?id=11943 https://lists.debian.org/debian-lts-announce/2018/01/msg00035.html https://usn.ubuntu.com/3550-1 https://usn.ubuntu.com/3550-2 • CWE-125: Out-of-bounds Read •

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.

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 •

The wwunpack function in libclamav/wwunpack.c in ClamAV 0.99.2 allows remote attackers to cause a denial of service (use-after-free) via a crafted PE file with WWPack compression. La función wwunpack en libclamav/wwunpack.c en ClamAV 0.99.2 permite que atacantes remotos provoquen una denegación de servicio (use-after-free) mediante un archivo PE manipulado con compresión WWPack. • https://bugzilla.clamav.net/show_bug.cgi?id=11798 https://github.com/varsleak/varsleak-vul/blob/master/clamav-vul/use-after-free/clamav-use-after-free-pe.md https://github.com/vrtadmin/clamav-devel/commit/dfc00cd3301a42b571454b51a6102eecf58407bc https://security.gentoo.org/glsa/201804-16 • CWE-416: Use After Free •
