An issue in
git-shell could allow remote users to run an interactive pager. From the update announcement:
... 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).
The announcement also notes:
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.
Further details can be found in the commit message which fixed the issue (3ec804490).
