Red Hat: Security update for Perl DBI

Perl DBI is a database access Application Programming Interface (API) for the Perl language. perl-DBD-Pg allows Perl applications to access PostgreSQL database servers. Two format string flaws were found in perl-DBD-Pg. A specially-crafted database warning or error message from a server could cause an application using perl-DBD-Pg to crash or, potentially, execute arbitrary code with the privileges of the user running the application. Updated packages are available from ftp.redhat.com.
