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. (CVE-2012-1151 )
Run yum update perl-DBD-Pg to update your system.
