CVE-2006-10003 (GCVE-0-2006-10003)

Vulnerability from cvelistv5 – Published: 2026-03-19 11:08 – Updated: 2026-03-19 17:20

Title

XML::Parser versions through 2.47 for Perl has an off-by-one heap buffer overflow in st_serial_stack

Summary

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

Severity ?

9.8 (Critical)

Vulnerability from github – Published: 2026-03-19 12:30 – Updated: 2026-03-19 18:31

Details

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

Severity ?

9.8 (Critical)
