| 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. |
