Details
It was discovered that Git incorrectly handled certain subcommands such as
cvsserver. A remote attacker could possibly use this issue via shell
metacharacters in modules names to execute arbitrary code.
This update also removes the cvsserver subcommand from git-shell by
default.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 17.04
Ubuntu 16.04
Ubuntu 14.04
In general, a standard system update will make all the necessary changes.
