[ANNOUNCE] Git v2.12.3 and others

Maintenance releases Git v2.4.12, v2.5.6, v2.6.7, v2.7.5, v2.8.5, v2.9.4, v2.10.3, v2.11.2, and v2.12.3 have been tagged and are now available at the usual places.

These are primarily to fix a recently disclosed problem with "git shell", which may allow a user who comes over SSH to run an interactive pager by causing it to spawn "git upload-pack --help" (CVE-2017-8386). Some (like v2.12.3) have other fixes that have been accumulating included as well.

"git-shell" is a restricted login shell that can be used on a server to prevent SSH clients from running any programs except those needed for git fetches and pushes. If you are not running a server, or if your server has not been explicitly configured to use git-shell as a login shell, you are not affected. Also note that sites running "git shell" behind gitolite are NOT vulnerable.
