CVE-2006-10003 (2026-03-19)

XML::Parser versions through 2.47 for Perl has an off-by-one heap buffer overflow in st_serial_stack. In the case (stackptr == stacksize - 1), the stack will NOT be expanded. Then the new value will be written at location (++stackptr), which equals stacksize and therefore falls just outside the allocated buffer. The bug can be observed when parsing an XML file with very deep element nesting

NAME

XML::Parser::Style::Debug - Debug style for XML::Parser

SYNOPSIS

use XML::Parser;
my $p = XML::Parser->new(Style => 'Debug');
$p->parsefile('foo.xml');

DESCRIPTION

This just prints out the document in outline form to STDERR. Nothing special is returned by parse.
