Description OSIDB Bzimport 2026-06-05 15:01:25 UTC 
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.
