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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.20%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
