CVE-2023-20052

Name of the Vulnerable Software and Affected Versions ClamAV versions 1.0.0 and earlier, 0.105.1 and earlier, and 0.103.7 and earlier

Description The vulnerability is due to enabling XML entity substitution that may result in XML external entity injection. An attacker could exploit this vulnerability by submitting a crafted DMG file to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to leak bytes from any file that may be read by the ClamAV scanning process.

Recommendations For ClamAV versions 1.0.0 and earlier, 0.105.1 and earlier, and 0.103.7 and earlier, consider disabling the DMG file parser until a patch is available. Restrict access to the ClamAV scanning process to minimize the risk of exploitation. Avoid using the XML entity substitution feature in the ClamAV scanning library until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
