Description TEJ RATHI 2023-02-17 08:24:01 UTC

CVE-2023-20052: Possible remote information leak vulnerability in the DMG file parser. 

Affects versions 1.0.0 and earlier, 0.105.1 and earlier, and 0.103.7 and earlier. 

This 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.
