Affected: Alpaquita:23: perl-dbi, Alpaquita:25: perl-dbi, Alpaquita:stream: perl-dbi

DBI versions before 1.651 for Perl do not enforce statement handle consistency with the row.

When the statement handle had no fields but the source row was non-empty, the internal row-buffer helper would read from a negative array index.

This could be triggered by a caller supplying inconsistent metadata and rows to the prepare method.

Affected: openEuler:22.03-LTS-SP4: perl-DBI, openEuler:24.03-LTS-SP1: perl-DBI, openEuler:24.03-LTS-SP3: perl-DBI, openEuler:24.03-LTS-SP4: perl-DBI, openEuler:20.03-LTS-SP4: perl-DBI

The DBI is the standard database interface module for Perl. It defines a set of methods, variables and conventions that provide a consistent database interface independent of the actual database being used. It is important to remember that the DBI is just an interface. The DBI is a layer of "glue" between an application and one or more database driver modules. It is the driver modules which do most of the real work. The DBI provides a standard interface and framework for the drivers to operate within. Security Fix(es):

DBI versions before 1.650 for Perl have a heap overflow when preparsing SQL statements with an extreme number of placeholders.

The fix for CVE-2026-10879 did not allocate enough memory to handle approximately 1.2-million placeholders.

DBI version 1.650 sets a hard limit of 99,999 placeholders.(CVE-2026-14739)

DBI::SQL::Nano versions from 1.42 before 1.651 for Perl have inverted <= and >= SQL operators on text.

DBI::SQL::Nano, DBI's built-in mini-SQL engine, evaluated WHERE predicates incorrectly in some cases. In the non-numeric string branch of the is_matched method, <= was evaluated using Perl's ge operator, and >= was evaluated using Perl's le operator.

SQL::Nano is the fallback query engine for DBI's file-backed drivers (DBD::File, DBD::DBM, CSV-style drivers) whenever SQL::Statement is not installed, and is forced whenever DBI_SQL_NANO=1. Queries over such tables use these predicates directly.
