Revision 820d7650cc670d3e4195aad3a5343158c316e8fa authored by Junio C Hamano on 26 July 2017, 17:24:20 UTC, committed by Junio C Hamano on 28 July 2017, 22:51:14 UTC
When commands like "git fetch" talk with ssh://$rest_of_URL/, the code splits $rest_of_URL into components like host, port, etc., and then spawns the underlying "ssh" program by formulating argv[] array that has: - the path to ssh command taken from GIT_SSH_COMMAND, etc. - dashed options like '-batch' (for Tortoise), '-p <port>' as needed. - ssh_host, which is supposed to be the hostname parsed out of $rest_of_URL. - then the command to be run on the other side, e.g. git upload-pack. If the ssh_host ends up getting '-<anything>', the argv[] that is used to spawn the command becomes something like: { "ssh", "-p", "22", "-<anything>", "command", "to", "run", NULL } which obviously is bogus, but depending on the actual value of "<anything>", will make "ssh" parse and use it as an option. Prevent this by forbidding ssh_host that begins with a "-".
