Description:
------------
We are doing "Runtime Behavior Analysis" on our Amazon EC2 instance and one of the rules for it is "Software Without Stack Cookies". The analysis said:

The following executable files on instance i-9bb14a8d do not support stack cookies: /usr/lib64/php/5.6/modules/mysqlnd_ms.so.
This rule detects the presence of third-party software that is compiled without support for stack cookies. Stack cookies increase system security by defending against stack-based buffer overflow and other memory corruption attacks.

Is it possible to do this build option? Preferably via PECL and not a self-compile as it will be easier to maintain than us building and keeping track of its updates.

We do not distribute binaries for Linux, so I'd recommend to contact the distro that the file came from.

I also got some recommendations like this, but with other PHP packages. Were you able to resolve the issue?

No we weren't able to. We also tried contacting the authors but it seemed like they disappeared off the face of the earth around 2 years ago. No social media account updates no nothing.
