What is CVE-2013-7491?

The DBI module for Perl, prior to version 1.628, contains a significant vulnerability that can lead to stack corruption. This issue arises when a user-defined function necessitates a substantial allocation of memory, resulting in an unsafe reallocation of the Perl stack. This could potentially allow attackers to exploit the memory handling processes, leading to unpredictable behavior or possible application crashes.
