OpenCVS

OpenCVS is a FREE implementation of the Concurrent Versions System, the most popular open source revision control software. It can be used as both client and server for repositories and provides granular access control over data stored in the repository. It aims to be as compatible as possible with other CVS implementations, except when particular features reduce the overall security of the system.

The OpenCVS project was started after discussions regarding the latest GNU CVS vulnerabilities that came out. Although CVS is widely used, its development has been mostly stagnant in the last years and many security issues have popped up, both in the implementation and in the mechanisms.
