Details
It was discovered that ClamAV incorrectly handled memory when the
CL_SCAN_GENERAL_COLLECT_METADATA scan option was enabled. A remote attacker
could possibly use this issue to cause ClamAV to crash, resulting in a
denial of service.

The problem can be corrected by updating your system to the following package versions:
Ubuntu 21.10

This update uses a new upstream release, which includes additional bug
fixes. In general, a standard system update will make all the necessary
changes.
