## Overview

A flaw was found in the perl-dbi package. A type confusion vulnerability in the profiling feature can lead to an invalid memory dereference, causing the application to crash and resulting in a Denial of Service (DoS). A user or attacker capable of supplying profiling configuration, such as through environment variables, can trigger this flaw during database handle destruction under specific profile path settings.
