Encode security issue?

Hello,

I notice that there is a new Encode release in CPAN and blead, including:

! Unicode/Unicode.xs
  Addressed the following:
    Date: Fri, 22 Jul 2011 13:58:43 +0200
    From: Robert Zacek <zacek <at> avast.com>
    To: perl5-security-report <at> perl.org
    Subject: Unicode.xs!decode_xs n-byte heap-overflow

Is there any more information available concerning the likely severity
or impact of this issue?

Thanks,
Dominic.
