What is CVE-2007-5116?

The vulnerability arises due to a buffer overflow in the polymorphic opcode support of the Regular Expression Engine found in Perl version 5.8. Attackers exploiting this flaw can manipulate regular expressions by switching between byte and Unicode (UTF) characters. This could ultimately enable the execution of arbitrary code within the context of the affected Perl application, leading to potential system compromise.
