This "No SA, no problem" pattern is reasonable for default case, and the vast majority of issues. This glibc issue, like heartbleed and others may be sufficiently high-profile to warrant special treatment, even if not in "SA" form. > However, a real problem *does* exist for Linux VMs and applications on > FreeBSD, so it could be addressed that way.

Yup, and let me make clear an out-there-in-the-world distinction between 'an advisory by freebsd security people ' and a FreeBSD "SA" the implementation format. ./koobs
