   1 Git v2.7.6 Release Notes
   2 ========================
   3
   4 Fixes since v2.7.5
   5 ------------------
   6
   7  * A "ssh://..." URL can result in a "ssh" command line with a
   8    hostname that begins with a dash "-", which would cause the "ssh"
   9    command to instead (mis)treat it as an option.  This is now
  10    prevented by forbidding such a hostname (which will not be
  11    necessary in the real world).
  12
  13  * Similarly, when GIT_PROXY_COMMAND is configured, the command is
  14    run with host and port that are parsed out from "ssh://..." URL;
  15    a poorly written GIT_PROXY_COMMAND could be tricked into treating
  16    a string that begins with a dash "-".  This is now prevented by
  17    forbidding such a hostname and port number (again, which will not
  18    be necessary in the real world).
  19
  20  * In the same spirit, a repository name that begins with a dash "-"
  21    is also forbidden now.
