Hi,

The following vulnerabilities were published for clamav.

CVE-2023-20197[0]:
| A vulnerability in the filesystem image parser for Hierarchical File
| System Plus (HFS+) of ClamAV could allow an unauthenticated, remote
| attacker to cause a denial of service (DoS) condition on an affected
| device.    This vulnerability is due to an incorrect check for
| completion when a file is decompressed, which may result in a loop
| condition that could cause the affected software to stop responding.
| An attacker could exploit this vulnerability by submitting a crafted
| HFS+ filesystem image to be scanned by ClamAV on an affected device.
| A successful exploit could allow the attacker to cause the ClamAV
| scanning process to stop responding, resulting in a DoS condition on
| the affected software and consuming available system resources.
| For a description of this vulnerability, see the ClamAV blog .


CVE-2023-20212[1]:
| A vulnerability in the AutoIt module of ClamAV could allow an
| unauthenticated, remote attacker to cause a denial of service (DoS)
| condition on an affected device.     This vulnerability is due to a
| logic error in the memory management of an affected device. An
| attacker could exploit this vulnerability by submitting a crafted
| AutoIt file to be scanned by ClamAV on the affected device. A
| successful exploit could allow the attacker to cause the ClamAV
| scanning process to restart unexpectedly, resulting in a DoS
| condition.
