Ubuntu Security Notice 552-1 - It was discovered that Perl's regular expression library did not correctly handle certain UTF sequences. If a user or automated system were tricked into running a specially crafted regular expression, a remote attacker could crash the application or possibly execute arbitrary code with user privileges.

OpenPKG Security Advisory 2007.23
Posted Nov 8, 2007
Authored by OpenPKG Foundation | Site openpkg.com

OpenPKG Security Advisory - 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 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.
