ClamAV 0.103.12 is a patch release with the following fixes:

  • CVE-2024-20506:
    Changed the logging module to disable following symlinks on Linux and Unix
    systems so as to prevent an attacker with existing access to the 'clamd' or
    'freshclam' services from using a symlink to corrupt system files.

    • 1.4.1
    • 1.3.2
    • 1.0.7
    • 0.103.12

    Thank you to Detlef for identifying this issue.
