DBI versions before 1.656 for Perl hang on a later open of a DBD::DBM table because a failed open_data does not release the table's lock. open_data creates the table's lock file and takes an exclusive flock on it for a CREATE, before the checks that can croak…

DBI versions before 1.656 for Perl crash via type confusion in dbi_profile when a database handle is destroyed under a Profile Path with an {attr} element. An {attr} element names a database handle attribute, which dbi_profile reads from the handle's inner ha…

DBI versions before 1.654 for Perl incorrectly treat numeric values as strings in FetchHashKeyName
DBI versions before 1.654 for Perl incorrectly treat numeric values as strings in FetchHashKeyName. fetchrow_hashref uses the string pointer of the FetchHashKeyName attribute as the key name without stringifying it first. When FetchHashKeyName has been set to…

DBI versions before 1.654 for Perl incorrectly treat numeric values as strings in sql_type_cast_svpv
DBI versions before 1.654 for Perl incorrectly treat numeric values as strings in sql_type_cast_svpv. When casting to SQL_NUMERIC, sql_type_cast_svpv passes the string pointer and length of the SV to grok_number without stringifying it first. An integer (IV) …

DBI versions before 1.653 for Perl load arbitrary modules via unvalidated dbm_type and dbm_mldbm attributes in DBD::DBM
DBI versions before 1.653 for Perl load arbitrary modules via unvalidated dbm_type and dbm_mldbm attributes in DBD::DBM. DBD::DBM passes the dbm_type and dbm_mldbm connect attributes to require without checking that the value names a module. require treats a …

DBI versions before 1.652 for Perl allow a heap out-of-bounds write via an unvalidated numeric placeholder that sets the binder counter in preparse
DBI versions before 1.652 for Perl allow a heap out-of-bounds write via an unvalidated numeric placeholder that sets the binder counter in preparse. preparse reserves seven output bytes per input byte, the width of the longest ':p99999' expansion. The ':N' br…

DBI versions before 1.652 for Perl allow a heap out-of-bounds write on 32-bit perl via an integer wraparound in the output buffer size computed by preparse
DBI versions before 1.652 for Perl allow a heap out-of-bounds write on 32-bit perl via an integer wraparound in the output buffer size computed by preparse. preparse reserves its output buffer with `newSV(strlen(statement) * 7 + 16)`, budgeting seven output b…

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

DBI::ProfileData versions before 1.651 for Perl do not limit the path index
DBI::ProfileData versions before 1.651 for Perl do not limit the path index. The path index column of profile dump files is used to allocate an array of data for the parser. An unbounded value allows an attacker to specify a large index and consume available …

DBD::File versions before 1.651 for Perl do not ensure the table file is not a symlink to an untrusted location
DBD::File versions before 1.651 for Perl do not ensure the table file is not a symlink to an untrusted location. The complete_table_name method builds the absolute table file path without checking whether the file is a symbolic link. A link inside the data di…

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 met…

DBI versions before 1.650 for Perl read one byte out-of-bounds in preparse when deleting an initial SQL comment
DBI versions before 1.650 for Perl read one byte out-of-bounds in preparse when deleting an initial SQL comment. The preparse method normalises SQL and removes comments. When the SQL starts with a comment line, the deletion of that line during normalisation l…

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…

DBI versions before 1.650 for Perl are vulnerable to code injection via caller-influenced Profile
DBI versions before 1.650 for Perl are vulnerable to code injection via caller-influenced Profile. When a string is assigned to a DBI handle's Profile attribute, DBI splits it into path, package and arguments, and interpolates the package part in a string eva…

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