https://notcve.org/view.php?id=CVE-2020-3481
A vulnerability in the EGG archive parsing module in Clam AntiVirus (ClamAV) Software versions 0.102.0 - 0.102.3 could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to a null pointer dereference. An attacker could exploit this vulnerability by sending a crafted EGG file to an affected device. An exploit could allow the attacker to cause the ClamAV scanning process crash, resulting in a denial of service condition. Una vulnerabilidad en el módulo de análisis de archivo EGG en Clam AntiVirus (ClamAV) Software versiones 0.102.0 - 0.102.3, podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio en un dispositivo afectado. • https://blog.clamav.net/2020/07/clamav-01024-security-patch-released.html https://lists.debian.org/debian-lts-announce/2020/08/msg00010.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/IJ67VH37NCG25PICGWFWZHSVG7PBT7MC https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/QM7EXJHDEZJLWM2NKH6TCDXOBP5NNYIN https://security.gentoo.org/glsa/202007-23 https://usn.ubuntu.com/4435-1 https://usn.ubuntu.com/4435-2 • CWE-476: NULL Pointer Dereference •

Mutt before 1.14.4 and NeoMutt before 2020-06-19 have a STARTTLS buffering issue that affects IMAP, SMTP, and POP3. When a server sends a "begin TLS" response, the client reads additional data (e.g., from a man-in-the-middle attacker) and evaluates it in a TLS context, aka "response injection."

CVSS: 6.3EPSS: 0%CPEs: 11EXPL: 0CVE-2020-3350 – Cisco AMP for Endpoints and ClamAV Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2020-3350
A vulnerability in the endpoint software of Cisco AMP for Endpoints and Clam AntiVirus could allow an authenticated, local attacker to cause the running software to delete arbitrary files on the system. The vulnerability is due to a race condition that could occur when scanning malicious files. An attacker with local shell access could exploit this vulnerability by executing a script that could trigger the race condition. A successful exploit could allow the attacker to delete arbitrary files on the system that the attacker would not normally have privileges to delete, producing system instability or causing the endpoint software to stop working.
