The remote host is missing an update as announced via advisory SSA:2004-108-02.
CVS is a client/server version control system. As a server, it is used to host source code repositories. As a client, it is used to access such repositories. This advisory affects both uses of CVS. A security problem which could allow a server to create arbitrary files on a client machine, and another security problem which may allow a client to view files outside of the CVS repository have been fixed with the release of cvs-1.11.15. Any sites running CVS should upgrade to the new CVS package.
