Title

DBI versions before 1.648 for Perl have a heap overflow when preparsing SQL statements with more than 9 binders

Summary

DBI versions before 1.648 for Perl have a heap overflow when preparsing SQL statements with more than 9 binders. The preparse method expands SQL placeholder characters to numbered binders of the form :pN, but only allocates three characters per binder in the buffer. Placeholders 10-99 require four characters, 100-999 require five characters, et cetera.

Severity

9.8 (Critical)

Vulnerability from github – Published: 2026-06-05 15:32 – Updated: 2026-06-08 18:31

Details

DBI versions before 1.648 for Perl have a heap overflow when preparsing SQL statements with more than 9 binders.

The preparse method expands SQL placeholder characters to numbered binders of the form :pN, but only allocates three characters per binder in the buffer. Placeholders 10-99 require four characters, 100-999 require five characters, et cetera.

Severity

9.8 (Critical)
