1 Git v2.7.6 Release Notes
2 ========================
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).
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).
20 * In the same spirit, a repository name that begins with a dash "-"
21 is also forbidden now.
