Git v2.7.6 Release Notes
========================
Fixes since v2.7.5
------------------
* A "ssh://..." URL can result in a "ssh" command line with a
hostname that begins with a dash "-", which would cause the "ssh"
command to instead (mis)treat it as an option. This is now
prevented by forbidding such a hostname (which will not be
necessary in the real world).
* Similarly, when GIT_PROXY_COMMAND is configured, the command is
run with host and port that are parsed out from "ssh://..." URL;
a poorly written GIT_PROXY_COMMAND could be tricked into treating
a string that begins with a dash "-". This is now prevented by
forbidding such a hostname and port number (again, which will not
be necessary in the real world).
* In the same spirit, a repository name that begins with a dash "-"
is also forbidden now.
