F5 Networks should have been branded a black sheep for its various TLS implementation screw ups (they are the prime reason TLSv1 is considered insecure), yet they came out mostly unscathed. We need to stop giving a free pass to horrid development practices that create massively vulnerable software.
Yes, and it also highlights that we need independent review of any code going into critical public infrastructure, no matter where it comes from.
I'm failing to find more information (googling for ssl issues on ssl termination equipment doesn't work well,) though it sounds like it'd be a good read - if you have any more details to share, please...
That said, most of the code coming out of telco vendors is complete crap, it is just endemic in the industry.
This is why I laugh when I see the CNCF talking about getting OpenNFV / MANO code into containers - they can barely deal with moving to VMs currently.
