Details

Javier Fernández-Sanguino Peña from the Debian Security Audit Project
discovered that the module DBI::ProxyServer in Perl’s DBI library
created a PID file in an insecure manner. This could allow a symbolic
link attack to create or overwrite arbitrary files with the privileges
of the user invoking a program using this module (like ‘dbiproxy’).

Now the module does not create a such a PID file by default.
