FreeBSD -- Remote code execution in ggatec(8)

Problem Description:
The ggatec(8) daemon does not validate the size of a response before writing
it to a fixed-sized buffer. This allows to overwrite the stack of ggatec(8).
Impact:
A malicious ggated(8) or an attacker in a priviledged network position can
overwrite the stack with crafted content and potentially execute arbitrary
code.
