Echo: libdbi-perl: security update to 1.656-1

medium Tenable Cloud Security Plugin ID 477469

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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: a dbm_mldbm value that is not a module name, a failing
 tie, or a missing data file. The croak unwinds before the table object is blessed, so nothing releases the
 lock, and the meta data holding the open descriptor stays cached on the database handle. The dbm_mldbm and
 dbm_type values come from the DSN or the connect attributes, so a caller that chooses the serializer or
 the storage backend can trigger the failure. The flock has no timeout, so a later open of that table (even
 through a separate database handle) blocks for as long as the handle holding the stale lock lives, in the
 same process or any other. (CVE-2026-111879)

Solution

Update the libdbi-perl library and its related packages to version 1.656-1 or later.
