Buffer Overflow Vulnerability in ClamAV Scanning Library Affecting Multiple Versions

CVE-2023-20032

Summary

On February 15, 2023, a vulnerability was disclosed in the HFS+ partition file parser of ClamAV, enabling potential malicious exploitation. The flaw arises from a lack of buffer size verification, leading to the possibility of a heap buffer overflow. An attacker can exploit this vulnerability by submitting a specifically crafted HFS+ partition file for scanning. A successful attack could result in arbitrary code execution with the same privileges as the ClamAV scanning process, or it could crash the process entirely, causing a denial of service (DoS) situation. For further details, please refer to the ClamAV blog.
