On Feb 15, 2023, the following vulnerability in the ClamAV scanning library
was disclosed: A vulnerability in the DMG 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 access sensitive information on an
affected device. 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.
