Subject: [PATCH] upstream: Sanitize scp filenames via snmprintf. To do this we
move
the progressmeter formatting outside of signal handler context and have the
atomicio callback called for EINTR too. bz#2434 with contributions from djm
and jjelen at redhat.com, ok djm@

Subject: [PATCH] upstream: check in scp client that filenames sent during
remote->local directory copies satisfy the wildcard specified by the user.
This checking provides some protection against a malicious server
sending unexpected filenames, but it comes at a risk of rejecting wanted
files due to differences between client and server wildcard expansion rules.
For this reason, this also adds a new -T flag to disable the check.

has been in snaps for ~1wk courtesy deraadt@
