Subject Summary: Programming Language
Subject Home: http://www.perl.com/
Subject Versions: 5.* <= 5.8.8

Vulnerability Id: CVE-2007-5116
Vulnerability Scope: global (not OpenPKG specific)

Attack Feasibility: run-time
Attack Vector: remote network
Attack Impact: arbitrary code execution

Description:
Will Drewry and Tavis Ormandy of the Google Security Team have
discovered a UTF-8 related heap overflow in the regular expression
compiler of the Perl [0] programming language, probably allowing
attackers to execute arbitrary code by compiling specially crafted
regular expressions. The bug manifests in a possible buffer overflow
in the polymorphic "opcode" support code, caused by ASCII regular
expressions that really are Unicode regular expressions.
