A buffer overflow vulnerability in prepared statements that could be possibly triggered by user supplied data was found in perl DBI driver for MySQL. Vulnerability is present in all releases at least back to versions 3.0 of the driver released in 2005.

Comment 8 Dhiru Kholia 2016-10-14 04:54:08 UTC 
On RHEL / Fedora, the FORTIFY_SOURCE compilation option catches this stack-based buffer overflow, and it turns a flaw which could result in arbitrary code execution into a mere crash. Our CVSS score reflects this fact.
