Description TEJ RATHI 2023-02-17 08:23:58 UTC

CVE-2023-20032: Ppossible remote code execution vulnerability in the HFS+ file parser. 

The issue affects versions 1.0.0 and earlier, 0.105.1 and earlier, and 0.103.7 and earlier. 

This vulnerability is due to a missing buffer size check that may result in a heap buffer overflow write. An attacker could exploit this vulnerability by submitting a crafted HFS+ partition file to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to execute arbitrary code with the privileges of the ClamAV scanning process, or else crash the process, resulting in a denial of service (DoS) condition.
