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).
