A vulnerability in the ARJ archive parsing module in Clam AntiVirus (ClamAV) Software versions 0.102.2 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 (5.06%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
