The MITRE CVE dictionary describes this issue as:

Statement
This issue does not affect Red Hat Enterprise Linux 3, 4, or 5.
This flaw can only lead to a denial of service if perl-HTML-Parser is used in conjunction with perl 5.10.1. If perl-HTML-Parser is used with earlier versions of perl, this flaw does not lead to a denial of service.
