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. (CVE-2020-3350)

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. (CVE-2020-3481)");
