CVE-2006-10003

Toddr Xml::parser buffer overflow

9.8 CRITICALEPSS 0.55%
  1. Published19 Mar 2026

Description

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
