DBD::File versions before 1.651 for Perl do not ensure the table file
is not a symlink to an untrusted location

Description
-----------
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 directory can point to a table file at any path outside of the
configured f_dir and f_dir_search directories.

Callers of file-based drivers can read or write files outside of the
data directory.

Problem types
-------------
- CWE-22 Improper Limitation of a Pathname to a Restricted Directory
   ('Path Traversal')
- CWE-59 Improper Link Resolution Before File Access ('Link Following')

Solutions
---------
Upgrade to version 1.651 or later.
