How to fix?

Upgrade clamav to version 0.97.8 or higher.

Overview

Affected versions of this package are vulnerable to Denial of Service (DoS). Integer underflow in the cli_scanpe function in pe.c in ClamAV before 0.97.8 allows remote attackers to cause a denial of service (crash) via a skewed offset larger than the size of the PE section in a UPX packed executable, which triggers an out-of-bounds read.
