CVE-2023-20032

Disclosure Date: March 01, 2023
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

Description

On Feb 15, 2023, the following vulnerability in the ClamAV scanning library was disclosed:

A vulnerability in the HFS+ partition file parser of ClamAV versions 1.0.0 and earlier, 0.105.1 and earlier, and 0.103.7 and earlier could allow an unauthenticated, remote attacker to execute arbitrary code.

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.

For a description of this vulnerability, see the ClamAV blog [”https://blog.clamav.net/”].
