Summary

The updated packages fix a security vulnerability:
A vulnerability in the Data-Loss-Prevention (DLP) module in Clam AntiVirus (ClamAV) Software versions 0.102.1 and 0.102.0 could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to an out-of-bounds read affecting users that have enabled the optional DLP feature. An attacker could exploit this vulnerability by sending a crafted email 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-2020-3123)
