The git-cvsserver subcommand is reachable from the git-shell subcommand even if CVS support has not been configured (however, the git-cvs package needs to be installed).
In addition to fixing the actual bug, this update removes the cvsserver subcommand from git-shell by default. Refer to the updated documentation for instructions how to re-enable in case this CVS functionality is still needed.
For the oldstable distribution (jessie), this problem has been fixed in version 1:2.1.4-2.1+deb8u5.
For the stable distribution (stretch), this problem has been fixed in version 1:2.11.0-3+deb9u2.
For the unstable distribution (sid), this problem has been fixed in version 1:2.14.2-1.
We recommend that you upgrade your git packages.");
