Description Robb Gatica 2024-02-07 23:09:32 UTC 
CVE-2024-20328: Fixed a possible command injection vulnerability in the "VirusEvent" feature of ClamAV's ClamD service. To fix this issue, we disabled the '%f' format string parameter.  ClamD administrators may continue to use the `CLAM_VIRUSEVENT_FILENAME`  environment variable, instead of '%f'. But you should do so only from within  an executable, such as a Python script, and not directly in the clamd.conf "VirusEvent" command.

Affected versions:
0.104 (all patch versions)
0.105 (all patch versions)
1.0.0 through 1.0.4 (LTS)
1.1 (all patch versions)
1.2.0 and 1.2.1
