CVE-2022-38150:

In Varnish Cache 7.0.0, 7.0.1, 7.0.2, and 7.1.0, it is possible to cause the Varnish Server to assert and automatically restart through forged HTTP/1 backend responses. An attack uses a crafted reason phrase of the backend response status line. This is fixed in 7.0.3 and 7.1.1.

Pleaes bump to 7.1.1.

I just put 7.1.1 in the tree.  Preliminary test on amd64 suggests that its ready for rapid stabilization.  I'll open a bug now.

7.1.1 is fully stable and I've taken all vulnerable versions off the tree.

Thanks! Impact is very low since this requires a malicious backend, so no GLSA, all done!
